PCM1803DB

ADCs/DACs - Special Purpose Overview

The PCM1803DB is a stereo audio analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a delta-sigma architecture to provide 24-bit resolution with a maximum sampling rate of 96 kSPS. The device features single-ended voltage inputs and communicates via a serial digital interface. It operates on a typical single supply voltage of 5 V and is housed in a 20-pin SSOP package. The component supports an operating temperature range from -25 °C to 85 °C, designed for surface-mount installation.

• Serial digital interface compatibility
• 20-pin SSOP surface-mount package

ADCs/DACs - Special Purpose Applications

• Audio recording systems
• Digital audio players
• Consumer audio equipment

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DB' corresponds to the SSOP-20 package and commercial temperature grade when sourcing. Confirm that the single-ended input requirement matches the system design, as other variants may support differential inputs. Ensure the 5V supply voltage aligns with the target application's power rails before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select the PCM1803DB when single-ended inputs are required for stereo audio conversion at 24-bit resolution. This model is suitable for applications operating within the -25 °C to 85 °C range. For differential input requirements or higher sampling rates, consider alternative models within the PCM180x family such as the PCM1804.

ADCs/DACs - Special Purpose Part Context

The PCM1803DB belongs to the PCM180x series of audio ADCs from Texas Instruments. This series focuses on high-performance audio conversion using delta-sigma modulation. The DB suffix specifically denotes the 20-lead Shrink Small Outline Package (SSOP), distinguishing it from tape-and-reel variants like the PCM1803DBR.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1803ADBR serves as a functional replacement with identical electrical specifications but differs in packaging format (tape and reel vs. tube). Verify pinout compatibility and thermal characteristics when substituting.
