PS9604

Stereo, 24-Bit, 192kHz PCM-to-PWM Converter

for Full Digital Power Amplifier

Features

Description

ꢀ Sampling Frequency: 32kHz to 192kHz

ꢀ 8X Oversampling at 96kHz

ꢀ 4X Oversampling at 192kHz

ꢀ Input Audio Data Word: 20-, 24-Bit

ꢀ 130 dB Dynamic Range

The PS9604 is a high performance, stereo, 24-bit,

192kHz PCM-to-PWM converter IC.

The PS9604 uses a state-of-the-art digital signal-

processing algorithm to convert input PCM signal to

PWM format without sacrificing the quality of audio

signal.

ꢀ 120 dB SNR (typical)

ꢀ Variable Modulation Index: 0.5 to 0.875

ꢀ PWM Switching Frequency: 256~384kHz

ꢀ Variable PWM Mapping Method: Both Class

AD, BD amplifications are supported

ꢀ Automatic Sample Rate Detection

ꢀ System Clock:

2048fs at 48kHz, 1024fs at 96kHz,

512fs at 192kHz

ꢀ Single 3.3 V Power Supply

ꢀ 28-Lead SOIC Package

The PS9604 can be used with various 8X

oversampling digital filters, for example, DF1704,

SM5847, and PMD200. It can be set up to use

different modulation indices and PWM mapping

methods.

The PS9604’s excellent SNR and ultra-low

distortion makes it suitable for a size-sensitive

consumer power amplifier application where high

performance is required, such as high-quality AV

receiver, digital TV, and hi-fi amplifiers. A high-end

quality full-digital amplifier can be built using the

PS9604, with minimal cost.
