Texas Instruments OPAx186 Precision Operational Amplifier

Texas Instruments OPAx186 Precision Operational Amplifier (Op Amp) is a low-power, 24V, rail-to-rail input and output zero-drift op amp. This amp features only 10µV of offset voltage (max) and 0.04µV/°C of offset voltage drift over temperature (max). This device is excellent for precision instrumentation, signal measurement, and active filtering applications.

The low quiescent current consumption of 90µA makes the Texas Instruments OPAx186 an excellent option for power-sensitive applications, such as battery-powered instrumentation and portable systems. Moreover, the high common-mode architecture and low offset voltage allow for high-side current shunt monitoring at the positive rail. This device provides robust ESD protection during shipment, handling, and assembly.
