AK5392

ASAHI KASEI [AK5392] AK5392 Enhanced Dual Bit ∆Σ 24Bit ADC General Description The AK5392 is a 24bit, 128x oversampling 2ch A/D Converterfor professional digital audio systems. The modulator in the AK5392 uses the new developed Enhanced Dual Bit architecture. This new architecture achieves the wider dynamic range, while keeping much the same superior distortion characteristics as conventional Single Bit way. The AK5392 performs 116dB dynamic range, so the device is suitable for professional studio equipments such as digital mixer, digital VTR etc. Features † † † † † † † † † † † † Enhanced Dual Bit ADC Sampling Rate: 1kHz∼ 54kHz Full Differential Inputs S/(N+D): 105dB DR: 116dB S/N: 116dB High Performance Linear Phase Digital Anti-Alias filter Passband: 0∼ 21.768kHz(@fs=48kHz) Ripple: 0.001dB Stopband: 110dB Digital HPF & Offset Calibration for Offset Cancel Master Clock: 256/384fs Power Supply: 5V±5%(Analog), 3∼ 5.25V(Digital) Power Dissipation: 470mW Package: 28pin SOP 0188-E-01 -1- 1997/11 ASAHI KASEI [AK5392] „ Ordering Guide AK5392-VS AKD5392 -10∼ +70° C 28pin SOP AK5392 Evaluation Board „ Pin Layout „ Compatibility with AK5391 1.
