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, analogto-
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.
