ABSTRACT:
An output circuit for use with an array of high dynamic range analog sensor produces a digital output signal from the array prior to multiplexing, so as to avoid analog multiplexing noise. The analog signals are converted to digital form using a simple, parallel analog-to-digital conversion process at the outputs of low noise array amplifiers. By latching the converted digital output signals into shift registers, the analog multiplex function is obviated and the full dynamic range capability of the detector-amplifier combination is made available.
