The OPA189IDGKR is a precision amplifier designed by Texas Instruments. It is a single, low-noise, MUX-friendly, zero-drift, rail-to-rail (RRO), CMOS precision operational amplifier with a frequency response of 14MHz. This 8-VSSOP device operates over a temperature range of -40 to 125°C and features a supply voltage range from 2.7V to 16V. It has rail-to-rail input and output stages, low offset voltage, low offset voltage temperature drift, and low noise. It also includes frequency compensation circuitry and an output short-circuit protection with precise current-limit and auto-restart functions. This device is ideal for applications that require low input/output bias currents, low noise conditions, and precision amplifying performance.
