Wolfson microelectronics release one silicon microphone use for, bring clear recording with many piece such as portable consumer’s apparatus of Mobile, portable media player, still life projection machine of figure, gamma camera, sail apparatus and noise cancel earphone.

The apparatus of first developed is that one pair is close, high SNR simulation microphone (and some figure WM7110 and WM7120) Consumer’s application, need low power using and high prominent quality. Two microphones use CMOS/MEMS membrane technology had a monopoly in of the company famous for AudioPlus true megaphone, this and use standard CMOS to cast the factory on the basis of its memorandum converter IP.

Small-scale WM7110 (4.72 millimetres x 3.76 millimetres x 1.25 millimetres) And ultracompact WM7120 (3.76 millimetres x 2.95 millimetres x 1.1 millimetres) The apparatus usually consumes 160µA. Two product offer improved 62 SNR (aggravate) Performance, reduced the floor of noise to meet and save the cost, clear sound transduction in the microphone. Apparatus too with 100 sound pressure rank, a high one linear and dull response of stage have percent 0.5 a large number of low quantity in harmony distorted wave the most.

Wolfson offers improved WM7110E and WM7120E edition of two pieces of apparatus too, is this giving? The first memorandum silicon microphone of the sensitiveness tolerance of dB.
