Features
Description
•
•
•
The TPA186x is a series of the newest high-supplyvoltage amplifiers with 30-μV low offset, low noise, and
stable high-frequency response. The TPA186x series
incorporates 3PEAK’s proprietary and patented design
techniques to achieve excellent AC performance with 6MHz bandwidth, 5-V/μs slew rate, and low distortion, while
drawing only 1.4-mA quiescent current per amplifier. The
common-mode input voltage range extends to V−, and the
outputs swing rail-to-rail.

Supply Voltage: 4.5 V to 40 V or ±2.25 V to ±20 V
Offset Voltage: ±30 μV Maximum
Differential Input Voltage Range to Supply Rail, can
Work as Comparator
Input Rail to −VS, Rail-to-Rail Output
Drive Any Capacitive Load
Bandwidth: 6 MHz, Slew Rate: 5 V/μs
Excellent EMI Suppress Performance: 85 dB at 1 GHz
The TPA186x series has an over-temperature protection
feature to guarantee chip safety. The output of
the TPA186x enters high impendence when the die
temperature reaches around 170°C, and recovers
the function when the die temperature is down to
around 150°C. The TPA186x series has a very small
power temperature coefficient, which is beneficial for
temperature-sensitive applications.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure
to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.
(2) The inputs are protected by ESD protection diodes to the negative power supply. If the input extends to more than 300
mV beyond the negative power supply, the input current should be limited to less than 10 mA.
(3) A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power
supply voltage and how many amplifiers are shorted. Thermal resistance varies with the amount of PC board metal
connected to the package. The specified values are for short traces connected to the leads.

TPA1861/TPA1862/TPA1864
40-V, 6-MHz, Zero-Drift Op Amps
Detailed Description
Overview
The TPA186x is a series of the newest high-supply-voltage amplifiers. The TPA186x series can operate on a single-supply
voltage (4.5 V to 40 V), or a split-supply voltage (±2.25 V to ±20 V), making them highly versatile and easy to use.
The power-supply pins should have local bypass ceramic capacitors (typically 0.01 μF to 0.1 μF). Parameters that exhibit
variance with regard to the operating voltage or temperature are presented in the Typical Performance Characteristics.

Application Information
Low-Side Current Sensing Application
Figure 18 shows the device configured in a low-side current sensing application. The low-side current sensing method is
to place a sense resistor between the load and the circuit ground. The voltage dropping across the resistor is amplified by
different amplifier circuits with the device. VREF can be used to add bias voltage to the output voltage. Particular attention
must be paid to the matching and precision of R1, R2, R3, and R4, to maximize the accuracy of the measurement.

Power Supply Recommendations
Place 0.1-μF bypass capacitors close to the power supply pins to reduce coupling errors from the noisy or high-impedance
power supplies.
