AD80066
FEATURES
GENERAL DESCRIPTION
16-bit, 24 MSPS analog-to-digital converter (ADC)
The AD80066 is a complete analog signal processor for imaging
4-channel operation up to 24 MHz (6 MHz/channel)
applications. It features a 4-channel architecture designed to sample
3-channel operation up to 24 MHz (8 MHz/channel)
and condition the outputs of linear charged coupled device (CCD)
Selectable input range: 3 V or 1.5 V peak-to-peak
or contact image sensor (CIS) arrays. Each channel consists of
Input clamp circuitry
an input clamp, correlated double sampler (CDS), offset digital-
Correlated double sampling
to-analog converter (DAC), and programmable gain amplifier
1×~6× programmable gain
(PGA), multiplexed to a high performance 16-bit ADC. For
±300 mV programmable offset
maximum flexibility, the AD80066 can be configured as a
Internal voltage reference Multiplexed byte-wide output Optional single-byte output mode 3-w.
