TLC320AD77CDB Description

The TLC320AD77CDB is a high-performance 24-bit stereo audio CODEC from Texas Instruments, designed for precision audio signal processing. Operating within a 3V to 3.6V supply range (both analog and digital), it integrates a single ADC and DAC with 100dB dynamic range and 100dB signal-to-noise ratio (SNR), ensuring high-fidelity audio conversion. The device employs sigma-delta modulation for superior noise performance and supports serial data interface for seamless integration with DSPs or microcontrollers. Packaged in a 28-pin SSOP tube, it is RoHS3 compliant and suitable for surface-mount applications, though it is now classified as obsolete.

TLC320AD77CDB Features

• 24-bit resolution for ultra-high precision audio processing.
• Stereo audio support with 100dB dynamic range (ADC/DAC) and 100dB SNR, ideal for professional-grade audio systems.
• Low-voltage operation (3V–3.6V) reduces power consumption in portable and embedded designs.
• Sigma-delta architecture minimizes noise and distortion.
• Serial interface simplifies connectivity with host processors.
• Surface-mount 28-SSOP package ensures compact PCB integration.
• Wide operating temperature range (0°C to 70°C) for robust performance in varied environments.

TLC320AD77CDB Applications

This CODEC excels in applications demanding high-resolution audio conversion, such as:

• Professional audio equipment: Mixers, recorders, and studio interfaces.
• Consumer electronics: High-end headphones, portable audio players, and home theater systems.
• Telecommunications: VoIP devices, conference systems, and digital handsets.
• Embedded systems: Medical audio devices, automotive infotainment, and industrial audio processing.

Conclusion of TLC320AD77CDB

The TLC320AD77CDB stands out for its exceptional audio clarity, low-power operation, and compact form factor, making it a strong choice for high-fidelity audio systems. While now obsolete, its 24-bit resolution and sigma-delta technology remain competitive for legacy designs. Engineers seeking reliable, high-performance audio CODECs for professional or embedded applications may still find this device valuable in specific use cases.
