The INA159 is a high slew rate, G = 1/5 difference amplifierconsisTIng of a precision op amp with a precision resistornetwork. The gain of 1/5 makes the INA159 useful tocouple ±10V signals to single-supply analog-to-digitalconverters (ADCs), parTIcularly those operaTIng on a single+5V supply. The on-chip resistors are laser-trimmed foraccurate gain and high common-mode rejecTIon. Excellenttemperature coefficient of resistance (TCR) tracking of theresistors maintains gain accuracy and common-moderejection over temperature. The input common-modevoltage range extends beyond the positive and negativesupply rails. It operates on a total of +1.8V to +5.5V singleor split supplies. The INA159 reference input uses tworesistors for easy mid-supply or reference biasing.The difference amplifier is the foundation of manycommonly-used circuits. The INA159 provides this circuitfunction without using an expensive external precisionresistor network. The INA159 is available in an MSOP-8surface-mount package and is specified for operation overthe extended industrial temperature range, −40°C to+125°C.
