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).
♦ 1.0 Million Pixels/sec Conversion Rate
♦ Built-In Clamp Circuitry for Black-Level
Correction or Correlated Double Sampling
♦ 64-Step PGA, Programmable from Gain = -2 to -10
♦ Auxiliary Mux Inputs for Added Versatility
♦ Compatible with a Large Range of CCDs
♦ 8-Bit ADC Included
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.
♦ Space-Saving, 24-Pin SO Package
Packaged in a 24-pin SO, the MAX1101 is available in
the commercial (0°C to +70°C) temperature range.
