AD9823:  Correlated Double Sampler (CDS)

Product Details


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.
