LM1971M

The LM1971M is one member of the LM1971 family which is designed as the digitally controlled 62 dB audio attenuator with/mute that can be used in (1)communication systems; (2)cellular phones and pagers; (3)personal computer audio control; (4)electronic music (MIDI); (5)sound reinforcement systems; (6)audio mixing automation. Also this device is controlled by a TTL/CMOS compatible 3-wire serial digital interface.

Features of the LM1971M are:(1)3-wire serial interface; (2)mute function; (3)click and pop free attenuation changes; (4)8-pin plastic DIP and SO packages available. And the key specifications of this device are:(1)total harmonic distortion 0.0008% (typ); (2)frequency response > 200 kHz (.3 dB) (typ); (3)attenuation range (excluding mute) 62 dB (typ); (4)dynamic range 115 dB (typ); (5)mute attenuation 102 dB (typ).

The absolute maximum ratings of the LM1971M can be summarized as:(1)supply voltage, VDD:15 V;(2)voltage at any pin:(GND-0.2V) to (VDD+0.2V);(3)ESD susceptibility:3000 V;(4)soldering information N package (10s):260°C;(5)power dissipation:150 mW;(6)junction temperature:150°C;(7)storage temperature:-65°C to +150°C.
