In precision data acquisition applications, the OPA211 series of op amps provides 700-ns settling time to 16-bit
accuracy throughout 10-V output swings. This ac performance, combined with only 125-μV of offset and 0.35-
μV/°C of drift over temperature, makes the OPA211 ideal for driving high-precision 16-bit analog-to-digital
converters (ADCs) or buffering the output of high-resolution digital-to-analog converters (DACs).
The OPA211 series is specified over a wide dual-power supply range of ±2.25 V to ±18 V, or for single-supply
operation from 4.5 V to 36 V.
This series of op amps is specified from T_A = –55°C to 210°C.

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.
