LH0084C Datasheet | National Semiconductor

Description The LH0084/LH0084C is a self-contained, high speed, high accuracy, digitally-programmable-gain instrumentation amplifier. It consists of paired FET-input variable-gain voltage-follower input stages followed by a differential-tosingle-ended output stage. The input stage is programmable in accurate gain stepsof1,2,5,or10controlled by the logic levels of a 2-bit TTL-patible digital input word. For additional flexibility, the output stage is pin-strappable to fixed gains of 1, 4, or 10 for an overall gain range of 1 to 100. Applications include increased dynamic range A-to-O converters, test systems, and post multiplexer amplifier for data acquisition systems. The device exhibits high input impedance, low offset voltage, high CMRR and PSRR, high speed, and excellent gain accuracy and gain non-linearity. The LH0084 is...
