_______________General Description

The MAX1101 is a highly integrated IC designed pri-

marily for digitizing the output of a linear CCD array. It

provides the components required for all necessary

analog functions, including clamp circuitry for black-

level correction or correlated double sampling (CDS), a

three-input multiplexer (mux), and an 8-bit analog-to-

digital converter (ADC).

The MAX1101 operates with a sample rate up to 1MHz

and with a wide range of linear CCDs. The logic inter-

face is serial, and a single input sets the bidirectional

data line as either data in or data out, thus minimizing

the I/O pins required for communication.

Packaged in a 24-pin SO, the MAX1101 is available in

the commercial (0°C to +70°C) temperature range.
