LMV1099

The LMV1099 is an uplink and downlink voice intelligibility enhancing analog IC, ideally suited for mobile handsets. Uplink voice intelligibility is improved by rejecting far-field noise through a unique two-microphone solution.

Features of the LMV1099 are:(1)noise reduction without DSP-type artifacts;(2)adapting AGC (automatic gain control) on ambient noise level & downlink signal strength;(3)downlink adjustable noise-reducing high pass filter;(4)separate uplink & downlink enable functions;(5)no added process delays;(6)low power consumption;(7)shutdown function;(8)maximum AGC Limiter;(9)differential inputs & outputs for noise immunity;(10)earpiece amplifier;(11)available in a 25-bump micro SMD.

The absolute maximum ratings of the LMV1099 can be summarized as:(1):the parameter is supply voltage,the rating is 6.0,the unit is V;(2):the parameter is storage temperature,the rating is -85 to +150,the unit is ;(3):the parameter is ESD rating,the rating is 2000,200,750,the unit is V;(4):the parameter is junction temperature,the rating is 150,the unit is ;(5):the parameter is mounting temperature infrared or convection (20 sec.),the rating is 235,the unit is ;(6):the parameter is thermal resistance,the rating is 70,the unit is /W;(7):the parameter is supply voltage,the rating is 2.7 to 5.5,the unit is V;(8):the parameter is I2CVDD,the rating is 1.7 to 5.5,the unit is V;(9):the parameter is temperature range,the rating is 40 to +85,the unit is .
