TDA8787AHL/C3,157

ADCs/DACs - Special Purpose Overview

The TDA8787AHL/C3,157 is a 10-bit analog-to-digital interface designed for CCD cameras. It integrates a correlated double sampling (CDS) circuit, a programmable gain amplifier (PGA), and a low-power ADC with an internal reference regulator. The device supports sampling frequencies up to 18 MHz and operates on a 3.0 V supply, consuming 170 mW at 2.7 V. It features a 3-wire serial interface for full programmability, including PGA gain control and pulse polarity selection. An additional 8-bit DAC provides system control outputs. The component is housed in a 48-lead LQFP package.
