INA271AIDR Description

Short technical summary and product information.

The Texas Instruments INA271AIDR is an analog current sense amplifier designed for precise current monitoring. It features a wide common-mode voltage range from -16V to +80V, independent of the supply voltage. This device offers a gain of 20 V/V and a bandwidth of up to 130 kHz, making it suitable for applications requiring accurate current measurements.

 

The INA271AIDR has a low input offset voltage of ±2500 µV (max) and a low input offset drift of ±2.5 µV/°C (typ). Its gain error is ±1% (max) with a gain drift of 50 ppm/°C (max). The amplifier operates over an industrial temperature range of -40°C to 125°C.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) surface mount package, the INA271AIDR is designed for ease of integration into printed circuit boards. It requires a power supply voltage between +2.7V and +18V and has a quiescent current of 700 µA (typ). The device also provides a provision for filtering, enhancing its versatility in different circuit designs.
