Conditions: V_CC = 4.5V, 8 kHz 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_SSP1, V_SSP2 and V_SSD are connected together.
REC , PLAY , FT , FWD , ERASE , VOL and RESET must be at V_CCD.
Balanced input signal applied between MIC+ and MIC- as shown in the applications example. Single-ended MIC+ or
MIC- input is recommended to be less than 100 mV p-p.
