PCM1802DB

ADCs/DACs - Special Purpose Overview

The PCM1802DB is a stereo audio analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 96 kSPS. The device utilizes a delta-sigma architecture with a serial digital interface, suitable for consumer audio applications. It operates on dual power supplies: an analog supply ranging from 2.7V to 3.6V or 4.5V to 5.5V, and a digital supply of 2.7V to 3.6V. The component is housed in a 20-lead SSOP package and functions within a temperature range of -40°C to 85°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm pinout and electrical characteristics. Ensure the procurement source provides valid traceability documentation. Confirm that the delivered components match the 20-SSOP package specification and meet the required industrial temperature grade for the intended application environment.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a stereo audio ADC with 24-bit resolution and 96 kHz sampling is required. It is appropriate for designs needing single-ended analog inputs and a serial interface. Verify that the system power rails support the specified analog voltage range of 2.7V to 5.5V and the digital range of 2.7V to 3.6V. Consider the 20-SSOP package dimensions for PCB layout constraints.

ADCs/DACs - Special Purpose Part Context

The PCM1802DB belongs to the PCM1802 family of audio ADCs from Texas Instruments. This series is designed for cost-sensitive consumer applications demanding good audio performance. The 'DB' suffix indicates the 20-SSOP package variant. Other variants in the family may offer different packaging options or slight electrical parameter variations, but share the core delta-sigma conversion architecture.
