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.
