PCM9211PT

Audio Special Purpose Overview

The PCM9211PT is a digital audio interface transceiver manufactured by Texas Instruments, designed for high-performance audio applications. It integrates stereo analog-to-digital converters (ADCs) and routing capabilities within a single package. The device supports sampling rates up to 216 kS/s with a resolution of 24 bits. It operates on dual power supplies ranging from 2.9 V to 3.6 V and 4.5 V to 5.5 V, consuming approximately 10 mA of operating current. Communication with the host system is facilitated through I2C and SPI interfaces. The component is housed in a 48-pin LQFP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Audio Special Purpose Procurement Notes

Verify the specific suffix 'PT' corresponds to the tray packaging variant when ordering. Confirm that the required supply voltages align with the specified 2.9–3.6 V and 4.5–5.5 V ranges. Ensure the design accommodates the LQFP-48 footprint and thermal requirements for the -40°C to +85°C operating range. Cross-reference the datasheet for pinout compatibility with existing PCB layouts.

Audio Special Purpose Selection Notes

Select the PCM9211PT when a combined transmitter and receiver solution with integrated stereo ADCs is required. This component is suitable for designs needing 24-bit resolution at sample rates up to 216 kHz. Consider the LQFP-48 package size and the need for dual power rails during the schematic phase. Verify that the I2C/SPI interface constraints meet the system's control architecture requirements.
