UT53108

The UT53108 is a voice record playback ic. It is a mixed signal segment speech recorder.The chip integrates microphone amplifier,D/A converter, and static SRAM.Recordings are stored in static SRAM,providing low power consumption.It greatly reduces the number of external components needed for application such as toys,greeting card and voice memo.Features of the UT53108 are:(1)operating voltage 2.6 to 5.5V; (2)builtin-in 256K bits SRAM; (3)modified ADM algorithm; (4)recording length:12sec; (5)built-in automatic gain control for microphone input ; (6)auto playback functional enable; (7)direct driver speaker ; (8)builtin-in oscillator; (9)on chip low pass filter; (10)input trigger pins:RECb,PLAYb,ERASEb; (11)SINGLE,MULTI segment mode ; (12)MULTI segment play all ; (13)sequential segment erase in MULTI segment mode.

The absolute maximum ratings of the UT53108 can be summarized as:(1)dc supply voltage:7.0V; (2)input voltage range:-0.5V to V+ +0.5V; (3)operating temperature:-10~70; (4)storage temperature:-50~150.

The electrical characteristics(Ta=25) of the UT53108 can be summarized as:(1)operating voltage:2.6~5.5V; (2)operating current:10mA; (3)standby current:5A; (4)audio output current:-1.5mA; (5)input high level:2.8V; (6)input low level:0.2V; (7)output high |(busy pin):-10mA; (8)output sink|(busy pin):4.0mA; (9)input resister:50 KOHM.If you want to know more information such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
