OPA2189IDR Texas Instruments Zero-Drift Operational Amplifier SOIC-8 | JTDZ Tech
OPA2189IDR — Overview
OPA2189IDR by Texas Instruments is a component in the Operational Amplifiers (Op Amps) - Zero-Drift Precision CMOS category, supplied by Shenzhen Jinteng Electronics Technology Co., Ltd. (JTDZ Tech) — an independent distributor serving OEMs, ODMs and EMS providers worldwide.
The OPA2189 is a dual-channel, ultra-low-noise, zero-drift, 36-V precision operational amplifier from Texas Instruments. It offers a 5-uV (max) offset voltage, 14-MHz gain bandwidth, 168-dB CMRR and a MUX-friendly, EMI-filtered input architecture with rail-to-rail output. Supplied as the IDR variant in an SOIC-8 (D) package and rated from -40C to +125C, it targets precision instrumentation, signal measurement and active-filtering applications.
