Texas Instruments TLV2186 Precision Zero-Drift Operational Amplifier

Texas Instruments TLV2186 Precision Zero-Drift Operational Amplifier is a low-power, 24V, rail-to-rail input and output zero-drift operational amplifier (op amp). The TLV2186 features only 10µV of offset voltage (typ.) and 0.1µV/°C of offset voltage drift over temperature (typ.). This device is great for precision instrumentation, signal measurement, and active filtering applications. Low quiescent current consumption (90µA) makes the Texas Instruments TLV2186 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 also provides robust ESD protection during shipment, handling, and assembly.
