TIPCM1807PWR
Overview
The PCM1807PWR is a high-performance, single-chip, stereo analog-to-digital converter (ADC) featuring a 24-bit delta-sigma architecture. It supports sampling rates up to 96kHz and includes an integrated analog antialiasing filter, making it a compact solution for digitizing high-quality audio signals. The device operates on dual power supplies (3.3V for digital and 5.0V for analog) and interfaces via standard I2S or SPI protocols.
Why Choose This Part
This ADC provides a high dynamic range of 99dB and a signal-to-noise ratio of 99dB, ensuring minimal signal degradation during conversion. It simplifies board design by integrating an analog low-pass antialiasing filter and offering a digital high-pass filter to remove DC offsets. The 14-TSSOP package and low power consumption of approximately 10.2mA at 96kHz make it ideal for space-constrained consumer electronics.
Applications
Key Specifications
Getting Started
Integration requires a system clock (SCKI), typically 256, 384, or 512 times the sampling frequency. Configure the device mode (Master/Slave and data format) via the MD0 and MD1 pins before powering up. Ensure clean decoupling for the 5V analog supply (VCC) and 3.3V digital supply (VDD) to maintain the specified -93dB noise floor.
