– PSRR:106dB
– AOL: 134dB
• GAIN-BANDWIDTH PRODUCT: 12kHz
• SUPPLY VOLTAGE: 1.8V to 5.5V
• microSIZE PACKAGES:
– SC70-5, SOT23-5, MSOP-8
The OPA369 and OPA2369 are ultra-low-power,
low-voltage operational amplifiers from Texas
Instruments designed especially for battery-powered
applications.
2
The OPAx369 operates on a supply voltage as low as
1.8V and has true rail-to-rail operation that makes it
useful for a wide range of applications. The
zerø-crossover feature resolves the problem of input
crossover distortion that becomes very prominent in
low voltage (< 3V), rail-to-rail input applications.
In addition to microsize packages and very low
quiescent current, the OPAx369 features 12kHz
bandwidth, low offset drift (1.75µV/°C, max), and low
noise 3.6µVPP (0.1Hz to 10Hz).
The OPA369 (single version) is offered in an SC70-5
package. The OPA2369 (dual version) comes in both
MSOP-8 and SOT23-8 packages.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

APPLICATION INFORMATION
The OPA369 family of operational amplifiers
minimizes power consumption and operates on
supply voltages as low as 1.8V. Power-supply
rejection ratio (PSRR), common-mode rejection ratio
(CMRR), and open-loop gain (AOL) typical values are
in the range of 100dB or better.
When designing for ultralow power, choose system
components
carefully.
To
minimize
current
consumption, select large-value resistors. Any
resistors will react with stray capacitance in the circuit
and the input capacitance of the operational amplifier.
These parasitic RC combinations can affect the
stability of the overall system. A feedback capacitor
may be required to assure stability and limit
overshoot or gain peaking.
Good layout practice mandates the use of a 0.1µF
bypass capacitor placed closely across the supply
pins.
OPERATING VOLTAGE
OPA369 series op amps are fully specified and tested
from +1.8V to +5.5V (±0.9V to ±2.75V). Parameters
that vary significantly with supply voltage are shown
in the Typical Characteristic curves.
The input common-mode voltage range of the
OPA369 family typically extends to each supply rail.
CMRR is specified from the negative rail to the
positive rail. See Figure 4, Normalized Offset Voltage
vs Common-Mode Voltage.
PROTECTING INPUTS FROM
OVER-VOLTAGE
Input currents are typically 10pA. However, large
inputs (greater than 500mV beyond the supply rails)
can cause excessive current to flow in or out of the
input pins. Therefore, in addition to keeping the input
voltage between the supply rails, it is also important
to limit the input current to less than 10mA. This
limiting is easily accomplished with an input resistor,
as shown in Figure 24.

INPUT COMMON-MODE VOLTAGE RANGE
The OPA369 family is designed to eliminate the input
offset transition region typically present in most
rail-to-rail
complementary
stage
operational
amplifiers, which allows the OPA369 family of
amplifiers to provide superior common-mode
performance over the entire input range.

BATTERY MONITORING
The low operating voltage and quiescent current of
the OPA369 series make it an excellent choice for
battery monitoring applications, as shown in
Figure 25. In this circuit, VSTATUS is high as long as
the battery voltage remains above 2V. A low-power
reference is used to set the trip point. Resistor values
are selected as follows:
1. Selecting RF: Select RF such that the current
through RF is approximately 1000x larger than
the maximum bias current over temperature:
VREF
RF =
1000(IBMAX)
1.2V
1000(50pA)
= 24MW » 20MW
2. Choose the hysteresis voltage,

adequate.
3. Calculate R1 as follows:

6. Calculate RBIAS: The minimum supply voltage for
this circuit is 1.8V. The REF1112 has a current
requirement of 1.2µA (max). Providing the
REF1112 with 2µA of supply current assures
proper operation. Therefore:

WINDOW COMPARATOR
If VIN falls below VL, the output of A2 is high, current
flows through D2, and VOUT is low. Likewise, if VIN
rises above VH, the output of A1 is high, current flows
through D1, and VOUT is low. The window comparator
threshold voltages are set as follows:
R2
VH =
´ VS
R 1 + R2
(5)
Figure 26 shows the OPA2369 used as a window
comparator. The threshold limits are set by VH and
VL, with VH > VL. When VIN < VH, the output of A1 is
low. When VIN > VL, the output of A2 is low.
Therefore, both op amp outputs are at 0V as long as
VIN is between VH and VL. This architecture results in
no current flowing through either diode, Q1 in cutoff,
with the base voltage at 0V, and VOUT forced high.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
