NE577

The NE577 is a kind of unity gain level programmable compandor designed for low power applications. NE577 is internally configured as an expandor and a compressor to minimize external component count. It is available in a 14-pin plastic DIP and SO packages. The NE577 applications include: (1)cordless telephones; (2)consumer audio; (3)wireless microphones; (4)modems; (5)electric organs; (6)hearing aids; (7)automatic level control; (8)high performance portable communication; (9)cellular radio.

There are some features of NE577 as follows: (1)operating voltage range: 1.8 to 7 V; (2)low power consumption (1.4 mA @ 3.6 V); (3)over 90 dB of dynamic range; (4)wide input/output swing capability (rail-to-rail); (5)low external component count; (6)ESD hardened; (7)0 dB level programmable (10 mVRMS to 1.0 VRMS).

The following is about the absolute maximum ratings of NE577: (1)VCC, supply voltage: 8 V; (2)TA, operating ambient temperature range: 0 to +70; (3)TSTG, storage temperature range: -65 to +150; (4)JA, thermal impedance: 90/W for DIP package and 125/W for SO package.
