6 / 16 page ADMP441 Data Sheet Rev. B | Page 6 of 16 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS 4 L/R 6 GND 3 WS 7 VDD 2 SD 8 CHIPEN 1 SCK 9 GND BOTTOM VIEW (Not to Scale) ADMP441 Figure 5. Pin Configuration Table 6. Pin Function Descriptions Pin No. Mnemonic Type Description 1 SCK Input Serial Data Clock for I²S Interface. 2 SD Output Serial Data Output for I²S Interface. This pin tristates when not actively driving the appropriate output channel. The SD trace should have a 100 kΩ pull-down resistor to discharge the line during the time that all microphones on the bus have tristated their outputs. 3 WS Input Serial Data-Word Select for I²S Interface. 4 L/R Input Left/Right Channel Select. When set low, the microphone outputs its signal in the left channel of the I²S frame; when set high, the microphone outputs its signal in the right channel. 5 GND Ground Ground. Connect to ground on the PCB. 6 GND Ground Ground. Connect to ground on the PCB. 7 V DD Power Power, 1.8 to 3.3 V. This pin should be decoupled to Pin 6 with a 0.1 μF capacitor. 8 CHIPEN Input Microphone Enable. When set low (ground), the microphone is disabled and put in power-down mode. When set high (V DD), the microphone is enabled. 9 GND Ground Ground. Connect to ground on the PCB. |
