DUAL DIFFERENTIAL COMPARATOR
DESCRIPTION
The UTC LM393 consists of two independent voltage
comparators, designed specifically to operate from a single power
supply over a wide voltage range.
FEATURES
* Single or dual supply operation.
* Wide operating supply range
(VCC=2V ~ 36V or ±1 ~ ±18V)
* Input common-mode voltage includes ground.
* Low supply current drain ICC=0.8mA (Typical).
* Low input bias current IBIAS=25nA (Typical).
* Output compatible with TTL, DTL, and CMOS logic system.
PROGRAMMABLE PRECISION REFERENCEDESCRIPTIONThe UTC TL431L is a three-terminal adjustable regulator with aguaranteed thermal stability over applicable temperature ranges.The output voltage may be set to any value between VREF(approximately 2.5V) and 20V with two external resistors. It providesvery wide applications, including shunt regulator, series regulator,switching regulator, voltage reference and others.FEATURES*Programmable output Voltage to 20V.*Low dynamic output impedance 0.2Ω.*Sink current capability of 1.0 ~ 100mA.*Equivalent full-range temperature coefficient of 50ppm/ °C typicalfor operation over full rated operating temperature range
