LM193N Dual Differential Comparator Wide 2V-36V Range Low 2mA Current Open-Collector Outputs Fast 1.3μs Response TO-5/DIP Packages - Ideal for Industrial/Auto Control Systems

Features

■ Wide single supply voltage range or dual supplies : +2V to +36V or ±1V to ±18V

■ Very low supply current (0.4mA) independent of supply voltage (1mW/ comparator at +5V)

■ Low input bias current: 25nA typ.

■ Low input offset current: ±5nA typ.

■ Low input offset voltage: ±1mV typ.

■ Input common-mode voltage range includes ground

■ Low output saturation voltage: 250mV typ. (Io = 4mA)

■ Differential input voltage range equal to the supply voltage

■ TTL, DTL, ECL, MOS, CMOS compatible outputs

Application

Industrial Control Systems

Overvoltage/undervoltage protection circuits

Threshold detection and monitoring

Position/speed sensing in motor control

Automotive Electronics

Battery management systems (overcharge/discharge protection)

Headlight/wiper control
Sensor signal processing (e.g., temperature/pressure threshold judgment)

Power Management

Feedback control for DC-DC converters

Power failure detection (e.g., voltage drop monitoring)

Consumer Electronics & Instrumentation

Level detection (e.g., battery level indication)

Waveform shaping (square wave generation)

Analog-to-digital signal interface circuits

Communication Equipment

Pulse-width modulation (PwM) signal processing

Signal edge triggering detection

Description

These devices consist of two independent low voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible.

These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.
