3 Description

The INA500 is a difference amplifier with integrated

op-amp and matched resistors that offers three gain

options. The INA500A version offers gain option of 1,

while the INA500B and INA500C versions offer gain

options of 0.50 and 0.25 respectively.

These are voltage sensing INAs in difference amplifier

configuration with high input impedance of >1MΩ and

low quiescent current of 13.5μA. The device achieves

75dB of minimum CMRR and an accurate ±0.05 of

maximum gain error, along with 3.5mV of maximum

offset (referred to output) in G = 1 configuration. The

device can handle up to 27.5V (±13.75V) of input

common-mode voltage in G = 0.25 with 5.5V (±2.75V)

of supply voltage. The combination of specifications

noted above are designed for a variety of level

translation and battery monitoring applications.

The precision matched integrated resistors of the

INA500 saves BOM costs and board space by

removing the need for precise and low tolerance

external resistors. The INA500 can interface directly

to low-speed, 8-bit to 12-bit, analog-to-digital

converters (ADC) and is an excellent choice

for replacing discrete implementation of difference

amplifiers built with commodity amplifiers and discrete

resistors. The INA500 is offered in standard 6-pin

packages such as SOT-23 and SC70 as well as the

space saving, X2SON package.
