PRODUCT HIGHLIGHTS

1. On-Chip Input Clamp and CDS

PRODUCT DESCRIPTION

The AD9801 is a complete CCD signal processor developed for

electronic cameras. It is well suited for both video conferencing

and consumer level still camera applications.

Clamp circuitry and high speed correlated double sampler

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

18 MSPS conversion rate.

The signal processing chain is comprised of a high speed CDS,

variable gain PGA and 10-bit ADC. Required clamping

circuitry and an onboard voltage reference are also provided.

The AD9801 operates from a single +3 V supply with a typical

power consumption of 185 mW.

2. On-Chip PGA

The AD9801 includes a low noise, wideband amplifier with

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

3. 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. (Typical DNL is ±0.5 LSB

and no missing code performance is guaranteed.)

The AD9801 is packaged in a space saving 48-pin thin-quad

flatpack (TQFP) and is specified over an operating temperature

range of 0°C to +70°C.

4. Low Power

At 185 mW, the AD9801 consumes a fraction of the power of

presently available multichip solutions. The part’s power-

down mode (15 mW) further enhances its desirability in low

power, battery operated applications.

5. Digital I/O Functionality

The AD9801 offers three-state digital output control.

6. Small Package

Packaged in a 48-pin, surface-mount thin-quad flatpack, the

AD9801 is well suited to very tight, low headroom designs.
