General 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-compatible 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.
