3 Description

The INA600 is a voltage-sensing difference amplifier with precision matched resistors that offer attenuating gain options. The precision matched integrated resistors saves BOM costs and board space by removing the need for precise and low tolerance external resistors.

The INA600 offers high input impedance of >1MΩ and low quiescent current of 65µA. The device can handle up to –40V to +85V of input voltage, attenuate the voltage down with great accuracy, and interface the voltage to the low voltage ADC while rejecting any common-mode errors such as ground bounce, switching ripples, AC mains and so forth. The device achieves a maximum gain error of ±0.05%, and a maximum gain drift of 5ppm/°C along with 89dB of minimum common-mode rejection ratio (G = 1/5).

This combination of specifications makes the INA600 a great choice for a variety of level translation, differential to single-ended applications, including any voltage monitoring of batteries or power rails. The INA600 interfaces directly to low-speed, analog-to-digital converters (ADC) and therefore is an excellent choice for replacing discrete implementation of difference amplifiers built with commodity amplifiers and discrete resistors. The INA600 is offered in standard 6-pin SOT-23 and SC70 packages.
