PCM1802DBR

ADCs/DACs - Special Purpose Overview

The PCM1802DBR is a stereo audio analog-to-digital converter manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 96 kHz. The device utilizes a sigma-delta architecture with single-ended inputs and communicates via a serial interface. It operates on dual power supplies, accepting analog voltages between 2.7 V and 3.6 V, and digital voltages between 4.5 V and 5.5 V. The component is housed in a 20-lead SSOP package with a width of 5.30 mm and is rated for operation within a temperature range of -40°C to 85°C.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 96 kHz maximum sampling rate
• Stereo configuration with two independent ADC channels
• Dual supply operation: 2.7V–3.6V analog and 4.5V–5.5V digital
• Serial data interface compatible with standard audio protocols

ADCs/DACs - Special Purpose Applications

• Professional audio recording equipment
• High-fidelity music players
• Audio processing systems requiring low noise performance

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging options such as tape and reel or cut tape. Confirm that the voltage requirements align with the system design, as the PCM1802 requires separate analog and digital supply rails. Check for any recent product change notices regarding assembly sites or marking updates before finalizing procurement plans.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a stereo audio ADC with 24-bit resolution and 96 kHz bandwidth is required. Ensure the design accommodates the distinct analog (2.7V–3.6V) and digital (4.5V–5.5V) power supply requirements. The 20-SSOP package must be considered for PCB layout constraints. Verify compatibility with the host processor's serial interface timing specifications.

ADCs/DACs - Special Purpose Part Context

The PCM1802 belongs to the PCM18xx series of audio analog-to-digital converters from Texas Instruments. This family focuses on high-performance audio conversion using sigma-delta modulation. The DBR suffix indicates the device is packaged in a 20-SSOP format and supplied in tape-and-reel packaging for automated surface-mount assembly processes.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1802DBRG4 is a lead-free variant of the same functional device. Other members of the PCM18xx family may offer different pin counts or sampling rates but require verification of electrical compatibility and pin mapping before substitution.
