The AK2304A is a kind of integrated monolithic quad PCM CODEC for PBX/KTS applications which integrates band limiting filters, ADCs, DACs and A-law/-law compressor/expander. The device can be set to either A-law or -law companding by pin selection.
There is some information about the AK2304A: (1)compliant to AT&T and ITU recommendations; (2)monolithic 4-channel CODEC/filter; (3)suitable for PBX/KTS applications; (4)A-law or -law pin selectable; (5)integrated op-amps for input gain adjustment; (6)integrated anti-alias filter; (7)2.048 Mb/s PCM data output; (8)individual channel mute function; (9)power down mode; (10)single 5 V operation; (11)44 pin QFP package.
The following is about the absolute maximum ratings of AK2304A: (1)DVDD (digital power supply): -0.3 to 6.5 V; (2)AVDD (analog power supply): -0.3 to 6.5 V; (3)VIND (digital input voltage): -0.3 to AVDD+0.3 V; (4)VINA (analog input voltage): -0.3 to AVDD+0.3 V; (5)Tstg (storage temperature): -55 to 125.
