I1964SYI is part of MLS ChipCorder® family that provides multiple-message record/playback with dual operating modes (address trigger and direct trigger) and wider operating voltage ranging from 2.4V to 5.5V. The sampling frequency can be selected from 4 to 12 kHz via an external resistor. The device is designed for standalone application, as well as controlled by microcontroller.
The analog input of I1964SYI can be selected as differential microphone input with AGC feature or single-ended analog input under feed-through mode.
The audio output can be selected as the differential Class-D PWM direct-drive or a single-ended voltage output (AUX out), depending on design needs.
