NE5044

The NE5044 is a programmable parallel input,serial output pulse width encoder.A multiplexed dual linear ramp technique is used to allow up to 7 inputs to be converted to a serial pulse width modulated signal with excellent linearity and minimal crosstalk.

Features of the NE5044 are:(1)3 to 7 channels,extemally selectable; (2)constant-current dual linear ramp for linearity better than 0.3%; (3)internal voltage reguator for low drift wide supply range 4.5 -12V; (4)fixed or variable frame rate set by extermal RC; (5)extermal control for channel gain or range; (6)versatile applications:exponential rates,mixing,dual tate,reversing, etc.; (7)compatible with all transmission mediums.

The absolute maximum ratings of the NE5044 can be summarized as:(1)VCC:13V; (2)IOUT:-25mA; (3)serial output peak current:30mA; (4)constant-current generator:-1mA; (5)parallel inputs,range input:0-VREG V; (6)one-shot input,frame generator input:0-VREG V; (7)TA:0 to 70; (8)TSTG:-65 to 150.

The electrical characteristics(Ta=25) of the NE5044 can be summarized as:(1)VCC:4.5~12V; (2)ICC:15mA 11 typ.If you want to know more information about NE5044 such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
