SA577D

The SA577D is a kind of unity gain level programmable low power compandor. SA577D is internally configured as an expandor and a compressor to minimize external component count. The typical applications include high performance portable communications, cellular radio, cordless telephone, consumer audio, wireless microphones, modems, electric organs, hearing aids and automatic level control (ALC).

There are some features of SA577D as follows: (1) operating voltage range: 1.8 to 7 V; (2) low power consumption (1.4 mA @ 3.6 V); (3) 0 dB level programmable (10mVRMS to 1.0 VRMS); (4) over 90 dB of dynamic range; (5) wide input/output swing capability (rail-to-rail); (6) low external component count; (7) ESD hardened.

What comes next is about the absolute maximum ratings of SA577D. (1): VCC (supply voltage) is 8 V;  (2): RthJA (thermal impedance) is 125/W; (3): Tstg (storage temperature range) is from -65 to +150; (4): TA (operating ambient temperature range) is from -40 to +85.
