PCM1604PT

ADCs/DACs - Special Purpose Overview

The PCM1604PT is a six-channel, 24-bit audio digital-to-analog converter utilizing enhanced multi-level delta-sigma architecture. It supports sampling rates from 10kHz to 200kHz with an 8x oversampling interpolation filter. The device features dual supply operation (+5V analog, +3.3V digital) and accepts standard, I2S, and Left-Justified data formats via a 5-wire serial interface. Key performance metrics include a typical dynamic range of 105dB, SNR of 104dB, and THD+N of 0.0018%. It operates within a temperature range of -25°C to +85°C in a QFP-48 package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix for the PCM1604PT against official documentation to confirm package type and tape/reel specifications. Confirm that the component meets required environmental operating temperatures and power supply voltage ranges for the target application design.

ADCs/DACs - Special Purpose Selection Notes

Select this component for multi-channel high-fidelity audio applications requiring low jitter tolerance and programmable digital filtering. Ensure the host system provides the necessary dual power supplies (+5V and +3.3V) and compatible serial clock interfaces for proper synchronization.

ADCs/DACs - Special Purpose Part Context

The PCM1604 is part of the Burr-Brown audio DAC family, sharing electrical characteristics and die with the PCM1605. It is designed as a pin-compatible replacement for earlier models like the PCM1600 and PCM1601, facilitating upgrades in existing multi-channel audio designs.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1605 is electrically identical and pin-compatible. Verify package availability (LQFP-48 vs MQFP-48) when substituting.
