DP7340 — 192 kHz 24-bit Dual-Channel Audio ADC

The DP7340 is a complete stereo analog-to-digital converter with built-in anti-aliasing filtering. It supports sampling rates up to 200 kHz per channel and delivers 24-bit resolution in standard serial audio formats.

Based on a fifth-order multi-bit ΔΣ modulator with a linear analog low-pass filter, the DP7340 automatically detects input signal and master clock frequencies, dynamically adjusting the sampling rate between 2 kHz and 200 kHz.

Ideal for high-dynamic-range, low-distortion, low-noise audio systems. Operates from 3.3 V or 5 V analog supply and supports 1.8–5 V digital logic levels. Package: TSSOP-16.
