PCM6480QRTVRQ1

ADCs/DACs - Special Purpose Overview

The PCM6480QRTVRQ1 is an automotive-grade analog-to-digital converter (ADC) from Texas Instruments, housed in a WQFN-32 package. It integrates four differential analog inputs and four digital audio serial interface (ASI) channels. The device operates on a supply voltage ranging from 3 V to 3.6 V with a typical operating current of 162.5 mA. It supports sampling rates up to 768 kHz and delivers a signal-to-noise ratio (SNR) of 110 dB and total harmonic distortion plus noise (THD+N) of -95 dB. Designed for harsh environments, it functions within a temperature range of -40°C to +125°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm pin compatibility and functional specifications. Ensure that any packaging variations do not alter the electrical characteristics or thermal performance required for the target application design.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a high-channel-count ADC with integrated digital interfaces is required for automotive audio. Verify that the system power budget accommodates the 162.5 mA operating current and that the PCB layout supports the WQFN-32 package thermal requirements.

ADCs/DACs - Special Purpose Part Context

This part belongs to the PCM6xxx-Q1 family of automotive audio ADCs. It shares the WQFN-32 footprint and general interface protocols with other members like the PCM6360QRTVRQ1, but differs in channel count and specific input configurations.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements include the PCM6360QRTVRQ1 for six-channel applications or the PCM6260QRTVRQ1 for mixed DAS/ADC/DAC needs. Verify register compatibility if migrating between different models in the same series.
