AK4309B - 16BIT SCF DAC FOR MULTIMEDIA

General Description

The AK4309B is a 1bit stereo DAC for multimedia audio systems.

A 1bit DAC can achieve monotonicity and low distortion with no adjustment and is superior to traditional R-2R ladder based DACs.

Key Features

  • † Sampling Rate Ranging from 8kHz to 50kHz † On chip Perfect filtering.
  • 8 times FIR Interpolator.
  • 2nd order SCF and CTF.
  • Total Response: ±0.5dB at 20kHz † On chip Buffer with Single End Output † Master Clock: 256fs or 384fs † High Tolerance to Clock Jitter † TTL Level Digital Interface † THD+N: -84dB † Dynamic Range: 90dB † Output Level: 3.4Vpp † Power Supply: 5V±10% † Low Power Dissipation: 80mW at 5V † Small Package: 20pin SSOP † Pin Compatible with AK4310/4309A 01.

ASAHI KASEI [AK4309B] AK4309B 16Bit SCF DAC for Multimedia General Description The AK4309B is a 1bit stereo DAC for multimedia audio systems. A 1bit DAC can achieve monotonicity and low distortion with no adjustment and is superior to traditional R-2R ladder based DACs. In the AK4309B, the loss of accuracy from clock jitter is also improved by using SCF techniques for on-chip post filter. The AK4309B includes continuous time filter with single end output and does not need any external parts. The master clock can be either 256fs or 384fs, supporting various audio environment. Features † Sampling Rate Ranging from 8kHz to 50kHz † On chip Perfect filtering • 8 times FIR Interpolator • 2nd order SCF and CTF • Total Response: ±0.
