AK4591

[AK4591] AK4591 24bit 4ch ADC with Input selector + 24bit 6ch DAC 1.General Description The AK4591 is a unique CODEC that combines both high performance and integration in a single chip. The uniqueness begins with the ADC input selector that can select 2 sets of stereo data from 9 sets of available stereo inputs. The 4ch ADC and 6 ch DAC offer high qualityanalog performance with 97dB (48 kHz) dynamic range on the ADC and 107dB (48 kHz) dynamic range on the DAC. This CODEC supports sampling frequencies from 8 kHz to 96 kHz and is suitable for rear seat entertainment to select and distribute 2 different sources in an automotive environment. The AK4591 is packaged in a 64-lead LQFP package offering an operational temperature range of -40°C to 85°C. 2.
