Abstract
An analog multiplexer connected to a plurality of input terminals selectively samples the input terminals in response to signals from a controller. The multiplexer includes a sample and ramp amplifier circuit for supplying the selected analog input to desired subsequent circuitry, for example, an analog-to-digital converter. The analog multiplexer is particularly useful in applications wherein a microprocessor periodically senses selected analog sensors and applies signals to control devices to regulate the conditions being sensed.
