Texas Instruments INA500 1.7V to 5.5V Difference Amplifiers include an integrated op-amp and matched resistors offering three gain options. The INA500A amplifiers offer a gain option of 1, while the INA500B and INA500C versions offer gain options of 0.50 and 0.25, respectively. The precision-matched integrated resistors of the INA500 save BOM costs and board space by removing the need for precise and low-tolerance external resistors. These amplifiers can interface directly to low-speed, 8-bit, and 12-bit ADC. The INA500 amplifiers are an excellent choice for replacing the discrete implementation of difference amplifiers built with commodity amplifiers and discrete resistors. These amplifiers are offered in standard 6-pin packages such as SOT-23 and SC70 and a space-saving X2SON package.
