Description
The PCM4204PAPR is a high-performance, 4-channel 24-bit, 216kHz delta-sigma ADC (Analog-to-Digital Converter) from Texas Instruments. It features ultra-low THD+N (Total Harmonic Distortion + Noise) and high dynamic range (123dB), making it ideal for professional audio applications like mixing consoles, digital recorders, and broadcast equipment.
Key features:
- 4-channel simultaneous sampling
- 24-bit resolution with 216kHz max sample rate
- 123dB dynamic range, -110dB THD+N
- Serial audio interface (I²S, left-justified)
- Single +5V supply operation
- TSSOP-28 package
The PCM4204PAPR supports master/slave clocking and includes digital high-pass filters for DC offset removal. Its robust performance and multi-channel capability suit high-end audio systems requiring precision and low noise.
For detailed specs, refer to the datasheet on TI’s website.
