The Texas Instruments OPA189ID is a single-channel, CMOS precision operational amplifier designed for high-performance applications. It features a zero-drift architecture, providing ultra-low offset voltage of 3 µV maximum and an offset drift of 0.005 µV/°C typical. With a gain bandwidth of 14 MHz and a slew rate of 20 V/µs, it delivers excellent dynamic performance.
The OPA189ID boasts low noise characteristics, with a voltage noise density of 5.2 nV/√Hz at 1 kHz, and a 0.1-Hz to 10-Hz noise of 0.1 µV PP. It offers high DC precision with a CMRR of 168 dB and an open-loop gain of 170 dB. The amplifier operates over a wide supply voltage range from 4.5 V to 36 V and features rail-to-rail input and output.
Key features include EMI hardening, high Cload drive capability, and MUX-friendly design. The device is available in VSSOP, SOT-23, and SOIC packages, suitable for surface-mount applications. Its precision and low noise make it ideal for various analog signal processing tasks where accuracy is critical.
