TDA8783HL/C5,118

ADCs/DACs - Special Purpose Overview

The TDA8783HL/C5,118 is a 10-bit analog-to-digital interface designed for CCD cameras. It integrates a correlated double sampling (CDS) circuit, an automatic gain control (AGC) amplifier, and a low-power 10-bit ADC with a reference regulator. The device supports sampling frequencies up to 40 MHz and features fully programmable bandwidths via a 3-wire serial interface. Key electrical parameters include a typical total power consumption of 483 mW, an AGC dynamic range of 30 dB, and operation with VCCA/VCCD at 5 V and VCCO between 2.5 V and 5.25 V.

ADCs/DACs - Special Purpose Feature Summary

• Integrated Correlated Double Sampling (CDS), AGC, and 10-bit ADC with adjustable bandwidths.
• Fully programmable via a 3-wire serial interface for gain, cutoff frequency, and standby modes.
• Includes an additional 8-bit DAC for analog system controls and a 10-bit DAC for ADC clamp level adjustment.
• Supports TTL compatible inputs and TTL/CMOS compatible digital outputs.

• CCD camera systems
• PC cameras
• Surveillance cameras
• Camcorders
• Digital still cameras

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix C5,118 against manufacturer documentation to confirm package variant and tape/reel specifications. Confirm RoHS compliance status as per the latest product change notification. Ensure the source document matches the exact part number to avoid discrepancies in pinout or electrical characteristics.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high-speed digitization of CCD signals with integrated signal conditioning. Ensure the design accommodates separate analog and digital supply decoupling to minimize noise. Verify that the serial interface timing requirements align with the host controller's capabilities for programming the internal DACs and standby modes.

ADCs/DACs - Special Purpose Part Context

The TDA8783 belongs to the TDA878 series of integrated circuits developed by Philips Semiconductors, now NXP. It serves as a specialized front-end interface for converting analog video signals from CCD sensors into digital data. The device consolidates multiple analog processing stages into a single LQFP48 package to simplify PCB layout and reduce component count in camera designs.

ADCs/DACs - Special Purpose Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternatives based on matching 10-bit resolution, 40 Msps sampling rate, and LQFP48 packaging constraints.
