INA2133UA Description

Short technical summary and product information.

The Texas Instruments INA2133UA is a precision difference amplifier designed for cost-optimized applications. It features a dual-channel configuration and operates over a wide supply voltage range of ±2.25V to ±18V (or +4.5V to +36V single supply).

 

Key electrical characteristics include a low input offset voltage of ±450µV maximum, a low offset voltage drift of ±5µV/°C maximum, and a low gain error of 0.05% maximum. The amplifier provides a wide small-signal bandwidth of 1.5 MHz and a high slew rate of 5V/µs (CSO: SHE) or 20V/µs (CSO: RFB). It also boasts a fast settling time of 5.5µs to 0.01% and a low quiescent current of 950µA.

 

The on-chip resistors are laser-trimmed for accurate gain and high common-mode rejection, with excellent tracking over temperature. The input common-mode voltage range extends beyond the supply rails.

 

This device is available in a 14-pin SOIC surface mount package, measuring 8.65 mm × 6 mm with an area of 51.9 mm². It is specified for operation across a wide temperature range of -55°C to 125°C.
