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.
