Low 1/f noise: 2 µV_PP(0.1 Hz to 10 Hz)

Low supply voltage operation: 1.7 V to 5.5 V

Low quiescent current: 1.22 mA

Fast settling: 0.75 µs (1 V to 0.1%)

Fast slew rate: 4.5 V/µs

High output current: +65/–55-mA short circuit

Gain bandwidth: 13 MHz

Rail-to-rail input and output

Specified temperature range: –40°C to +125°C

EMI and RFI filtered inputs

The OPAx392 family of operational amplifiers

(OPA392, OPA2392, and OPA4392) features ultra-low

offset, offset drift, and input bias current with rail-to-rail

input and output operation. In addition to precision

dc accuracy, the ac performance is optimized for

low noise and fast-settling transient response. These

features make the OPAx392 an excellent choice

for driving high-precision analog-to-digital converters

(ADCs) or buffering the output of high-resolution,

digital-to-analog converters (DACs).

The OPAx392 feature TI's e-trim^™operational

amplifier technology to achieve ultra-low offset

voltage and offset voltage drift without any input

chopping or auto-zero techniques. This technique

enables ultra-low input bias current for sensor inputs

or photodiode current-to-voltage measurements,

creating high-performance transimpedance stages for

optical modules or medical instrumentation.
