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.
