OPA2189IDGKR Description

Short technical summary and product information.

The Texas Instruments OPA2189IDGKR is a dual-channel, precision operational amplifier designed for high-performance applications. It features a 14-MHz gain bandwidth product and a low offset voltage of 0.005 mV at 25°C, with an offset drift of 0.006 µV/°C. This zero-drift amplifier provides excellent accuracy and stability over temperature variations.

 

With a total supply voltage range of 4.5V to 36V, the OPA2189IDGKR is suitable for a wide array of power requirements. It boasts a high Common Mode Rejection Ratio (CMRR) of 168 dB and a low noise voltage spectral density of 5.2 nV/√Hz at 1 kHz, making it ideal for sensitive signal processing tasks. The amplifier also features rail-to-rail input and output swing, allowing for maximum dynamic range.

 

Designed with EMI hardening and high Cload drive capabilities, this CMOS operational amplifier operates within a temperature range of -40°C to 125°C. It is available in VSSOP (DGK) and SOIC (D) packages, offering flexibility for different PCB layouts and space constraints. The low THD+N of 0.00006% at 1 kHz ensures high signal fidelity.

 

This precision op amp is well-suited for applications requiring high accuracy, low noise, and stable performance, such as sensor signal conditioning, active filters, and high-precision analog circuits.
