3 Description
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.
