High Speed Portable Devices
Multiplexing Applications (LMH6647)
Current Sense Buffer
High Speed Transducer Amp
The LMH6645 (single) and LMH6646 (dual), rail-torail input and output voltage feedback amplifiers, offer
high speed (55 MHz), and low voltage operation (2.7
V) in addition to micro-power shutdown capability
(LMH6647, single).
Input common mode voltage range exceeds either
supply by 0.3 V, enhancing ease of use in multitude
of applications where previously only inferior devices
could be used. Output voltage range extends to
within 20 mV of either supply rails, allowing wide
dynamic range especially in low voltage applications.
Even with low supply current of 650 μA/amplifier,
output current capability is kept at a respectable ±20
mA for driving heavier loads. Important device
parameters such as BW, Slew Rate and output
current are kept relatively independent of the
operating supply voltage by a combination of process
enhancements and design architecture.

5 Description (continued)
In portable applications, the LMH6647 provides shutdown capability while keeping the turn-off current to less
than 50 μA. Both turn-on and turn-off characteristics are well behaved with minimal output fluctuations during
transitions. This allows the part to be used in power saving mode, as well as multiplexing applications. Miniature
packages (SOT-23, VSSOP-8, and SOIC-8) are further means to ease the adoption of these low power high
speed devices in applications where board area is at a premium.

conditions, see the Electrical Characteristics.
If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in
exceeding the maximum allowed junction temperature of 150°C.
Output short circuit duration is infinite for VS < 6 V at room temperature and below. For VS > 6 V, allowable short circuit duration is 1.5
ms.
The maximum power dissipation is a function of TJ(MAX), RθJA, and TA. The maximum allowable power dissipation at any ambient
temperature is PD = (TJ(MAX) - TA)/ RθJA. All numbers apply for packages soldered directly onto a PC board.

Typical values represent the most likely parametric norm.
Slew rate is the average of the rising and falling slew rates.
Positive current corresponds to current flowing into the device.
Offset voltage average drift determined by dividing the change in VOS at temperature extremes into the total temperature change.

8 Detailed Description
8.1 Overview
The LMH664x family is based on proprietary VIP10 dielectrically isolated bipolar process.
This device family architecture features the following:
• Complimentary bipolar devices with exceptionally high ft (∼8 GHz) even under low supply voltage (2.7 V) and
low Collector bias current.
• Rail-to-Rail input which allows the input common mode voltage to go beyond either rail by about 0.5 V
typically.
• A class A-B “turn-around” stage with improved noise, offset, and reduced power dissipation compared to
similar speed devices (patent pending).
• Common Emitter push-pull output stage capable of 20 mA output current (at 0.5 V from the supply rails) while
consuming only ∼700 μA of total supply current per channel. This architecture allows output to reach within
mV of either supply rail at light loads.
• Consistent performance from any supply voltage (2.7 V to 10 V) with little variation with supply voltage for the
most important specifications (BW, SR, IOUT, for example)

switch (transistor) could be used to shunt the output to ground. Figure 43 shows a circuit where a NPN bipolar is
used to keep the output near ground (∼ 80 mV):

8.4 Device Functional Modes
The LMH6647 can be shutdown to save power and reduce its supply current to less than 50 μA ensured, by
applying a voltage to the SD pin. The SD pin is “active high” and needs to be tied to V− for normal operation. This
input is low current (< 20 μA, 4 pF equivalent capacitance) and a resistor to V− (≤ 20 kΩ) will result in normal
operation. Shutdown is ensured when SD pin is 0.4V or less from V+ at any operating supply voltage and
temperature.
In the shutdown mode, essentially all internal device biasing is turned off in order to minimize supply current flow
and the output goes into Hi-Z (high impedance) mode. Complete device Turn-on and Turn-off times vary
considerably relative to the output loading conditions, output voltage, and input impedance, but is generally
limited to less than 1μs (see tables for actual data).
As seen in Figure 42 in shutdown, there may be current flow through the internal diodes shown, caused by input
potential, if present. This current may flow through the external feedback resistor and result in an apparent output
signal. In most shutdown applications the presence of this output is inconsequential. However, if the output is
“forced” by another device such as in a multiplexer, the other device will need to conduct the current described in
order to maintain the output potential.
The total input common mode voltage range, which extends from below V− to beyond V+, is covered by both an
NPN and a PNP stage. The NPN stage is switched on whenever the input is less than 1.2 V from V+ and the
PNP stage covers the rest of the range. In terms of the input voltage, there is an overlapping region where both
stages are processing the input signal. This region is about 0.5 V from beginning to the end. As far as the device
application is concerned, this transition is a transparent operation. However, keep in mind that the input bias
current value and direction will depend on which input stage is operating (see Figure 29). For low distortion
applications, it is best to keep the input common mode voltage from crossing this transition point. Low gain
settling applications, which generally encounter larger peak-to-peak input voltages, could be configured as
inverting stages to eliminate common mode voltage fluctuations.
In terms of the output, when the output swing approaches either supply rail, the output transistor will enter a
quasi-saturated state. A subtle effect of this operational region is that there is an increase in supply current in this
state (up to 1 mA). The onset of Quasi-saturation region is a function of output loading (current) and varies from
100 mV at no load to about 1 V when output is delivering 20 mA, as measured from supplies. Both input
common mode voltage and output voltage level affect the supply current (see Figure 32).
With 2.7V supplies and a common mode input voltage range that extends beyond either supply rail, the
LMH664x family is well suited to many low voltage/low power applications. Even with 2.7 V supplies, the -3dB
BW (@ AV = +1) is typically 55 MHz with a tested limit of 45 MHz. Production testing guarantees that process
variations will not compromise speed.
This device family is designed to avoid output phase reversal. With input over-drive, the output is kept near the
supply rail (or as close to it as mandated by the closed loop gain setting and the input voltage). Figure 45, below,
shows the input and output voltage when the input voltage significantly exceeds the supply voltages.
The output does not exhibit any phase reversal as some op amps do. However, if the input voltage range is
exceeded by more than a diode drop beyond either rail, the internal ESD protection diodes will start to conduct.
The current flow in these ESD diodes should be externally limited.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The LMH664x family is well suited to many low voltage/low power applications and is designed to avoid output
phase reversal. Figure 45, for example, depicts the Input/Output Shown with Exceeded Input CMVR and
functions as a 2:1 MUX operating on a single 2.7-V power supply by utilizing the shutdown feature of the
LMH6647.

9.2.1 Design Requirements
This application requires fast, glitch-less transition between selected channels. The LMH6647 turn on and turn off
times are 250 ns and 560 ns respectively. Transition between channels is devoid of any excessive glitches.
9.2.2 Detailed Design Procedure
In this application, the LMH6647 output pins are directly tied to each other. The shutdown pin of each LMH6647
is driven in-opposite sense of the other (that is, “Low” on 1st LMH6647 with “High” on the 2nd LMH6647, and
vice versa). When shutdown is invoked, the device output enters Hi-Z state, while the alternate LMH6647 is
being powered on simultaneously. This way, the shutdown function serves the dual purpose of allowing only the
input associated with device which is not in shutdown to be selected and to appear at the output.

10 Power Supply Recommendations
The LMH664x device family can operate off a single supply or with dual supplies. The input CM capability of the
parts (CMVR) extends covers the entire supply voltage range for maximum flexibility. Supplies should be
decoupled with low inductance, often ceramic, capacitors to ground less than 0.5 inches from the device pins.
The use of ground plane is recommended, and as in most high speed devices, it is advisable to remove ground
plane close to device sensitive pins such as the inputs.

11 Layout
11.1 Layout Guidelines
Generally, a good high-frequency layout will keep power supply and ground traces away from the inverting input
and output pins. Parasitic capacitances on these nodes to ground will cause frequency response peaking and
possible circuit oscillations. For more information, see Application Note OA-15, Frequent Faux Pas in Applying
Wideband Current Feedback Amplifiers (SNOA367).
Another important parameter in working with high speed/high performance amplifiers is the component values
selection. Choosing large valued external resistors will affect the closed loop behavior of the stage because of
the interaction of these resistors with parasitic capacitances. These capacitors could be inherent to the device or
a by-product of the board layout and component placement. Either way, keeping the resistor values lower will
diminish this interaction. On the other hand, choosing very low value resistors could load down nodes and will
contribute to higher overall power dissipation.
