PRODUCT DESCRIPTION

The AD9823 is a correlated double sampler for digital camera

applications. It features a 40 MHz CDS amplifier with 3.5 dB of

fixed gain, an internal voltage reference supply, and timing

control for the SHP and SHD sampling clocks. Output buffers

are also included, providing drive strength for PCB traces and

direct connection to an image signal processor such as the

AD9821.

The AD9823 is ideal for applications that need to place the CDS

and VGA/ADC circuits on separate PC boards. The “pseudo

differential” outputs of the AD9823 provide good signal

integrity when interfaced with the differential input AD9821.

The AD9823 operates from a single 3 V power supply, typically

dissipates 50 mW, and is packaged in a 14-lead TSSOP package.
