AD9823 is a correlated double sampler (CDS) supporting 40MHz sampling frequency, fixed gain of 3.5dB, internal voltage reference supply, supporting SHP and SHD sampling clocks.
The AD9823 is a correlated double sampler designed for digital camera applications. It features a 40 MHz CDS amplifier with a fixed 3.5 dB gain, operates from a single 3 V supply, and includes internal reference and timing control for SHP and SHD sampling clocks. Output buffers provide drive strength for PCB traces and direct connection to image signal processors such as the AD9821.
The datasheet provides comprehensive specifications, including general, analog, digital, and timing parameters, absolute maximum ratings, thermal characteristics, pin configurations, and ordering information for the 14‑lead TSSOP (RU‑14) package.
