T he AD9802 is a complete CCD signal processor developed

for electronic cameras. It is suitable for both camcorder and

consumer-level still camera applications.

1. On-Chip Input Clamp and CDS

Clamp circuitry and high speed correlated double sampler

allow for simple ac-coupling to interface a CCD sensor at full

18 MSPS conversion rate.

T he signal processing chain is comprised of a high speed CDS,

variable gain PGA and 10-bit ADC. Required clamping cir-

cuitry and an onboard voltage reference are provided as well as a

direct ADC input. T he AD9802 operates from a single +3 V

supply with a typical power consumption of 185 mW.

2. On-Chip PGA

The AD9802 includes a low-noise, wideband amplifier with

analog variable gain from 0 dB to 31.5 dB (linear in dB).

3. Direct ADC Input

T he AD9802 is packaged in a space saving 48-terminal thin

quad flatpack (T QFP) and is specified over an operating tem-

perature range of 0°C to +70°C.

A direct input to the 10-bit A/D converter is provided for

digitizing video signals.

4. 10-Bit, High Speed A/D Converter

A linear 10-bit ADC is capable of digitizing CCD signals at

the full 18 MSPS conversion rate. T ypical DNL is ±0.5 LSB

and no missing code performance is guaranteed.

5. Low Power

At 185 mW, and 15 mW in power-down, the AD9802 con-

sumes a fraction of the power of presently available multichip

solutions.

6. Digital I/O Functionality

T he AD9802 offers three-state digital output control.

7. Small Package

Packaged in a 48-terminal, surface-mount thin quad flatpack,

the AD9802 is well suited to very compact, low headroom

designs.
