Conditions: V_CC = 4.5V, 8kHz sampling frequency and T_A = 25°C, unless otherwise stated.
LED output during Record operation.
V_CCA, V_CCD and V_CCP are connected together. V_SSA, V_SSP and V_SSD are connected together.
REC , PLAYE and PLAYL must be at V_CCD.
REC , PLAYE and PLAYL are forced to specified condition.
Balanced input signal applied between MIC and MIC REF as shown in the applications example. Single-
ended MIC or MIC REF recommended to be less than 100 mV peak to peak.
