TDA8787AHL/C3,118

ADCs/DACs - Special Purpose Overview

The TDA8787AHL/C3,118 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 an ADC with a reference regulator. The device supports sampling frequencies up to 18 MHz and operates on a 3.0 V supply, with digital outputs compatible with 2.5 to 3.6 V. Key electrical parameters include a maximum pixel frequency of 18 MHz, a PGA dynamic range of 36 dB, and total power consumption of 190 mW at 3.0 V or 170 mW at 2.7 V. It features TTL-compatible inputs and CMOS-compatible outputs.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix /C3,118 against current NXP documentation to confirm package type and compliance status. Check product status as older specifications may indicate end-of-life or obsolescence. Ensure compatibility with existing PCB footprints for the LQFP48 package before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high-speed digitization of CCD signals with integrated noise reduction. The 10-bit resolution and 18 MHz speed suit most consumer imaging needs. Consider the 3.0 V operating voltage and ensure the system design accommodates the separate analog and digital supply requirements for optimal noise performance.

ADCs/DACs - Special Purpose Part Context

The TDA8787A is part of NXP's (formerly Philips Semiconductors) line of specialized consumer ICs for video signal processing. It serves as a dedicated front-end interface for CCD sensors, combining analog conditioning and digital conversion in a single package to simplify camera system design.
