TIPCM1807PW
Overview
The PCM1807PW is a high-performance, single-chip, stereo analog-to-digital converter designed for consumer audio applications. It features a 24-bit delta-sigma modulator and supports sampling rates up to 96kHz while maintaining low power consumption. The device includes an integrated analog antialiasing low-pass filter and supports both SPI and I2S interfaces for flexible system integration.
Why Choose This Part
The PCM1807PW offers a high dynamic range of 99dB and a signal-to-noise ratio of 99dB, ensuring clean audio capture. Its dual-supply architecture (3.3V and 5V) allows for optimized analog performance while staying compatible with low-voltage digital logic. Engineers benefit from the integrated fade-in/fade-out functions and polarity control which simplify system-level audio management.
Applications
Key Specifications
Getting Started
To evaluate this part, use a breakout board for the 14-TSSOP package and interface it with a microcontroller via the I2S bus for data and SPI for control. Ensure that the analog and digital power supplies are properly decoupled with low-ESR capacitors as close to the pins as possible. Review the system clock (SCKI) requirements in the datasheet to match your desired sampling rate of 48kHz or 96kHz.
