PIN CONFIGURATIONS AND FUNCTION DESCRIPTIONS
3 GND SELECT 4 2 CLK DATA 5 1 VDD
Figure 3. Pin Configuration (Top View, Terminal Side Down)
TABLE 9. PIN FUNCTION DESCRIPTIONS PIN NAME FUNCTION
1 DATA Digital Output Signal (DATA1 or DATA2) Left Channel or Right Channel Select: DATA 1 (right): SELECT tied to GND 2 SELECT DATA 2 (left): SELECT tied to VDD. In this setting, SELECT should be tied to the same voltage source as the VDD pin. 3 GND Ground 4 CLK Clock Input to Microphone Power Supply. For best performance and to avoid potential parasitic artifacts, place a 0.1 µF 5 VDD (100 nF) ceramic type X7R capacitor between Pin 5 (VDD) and ground. Place the capacitor as close to Pin 5 as possible. Page 10 of 22 Document Number: DS‐000357 Revision: 1.0
