LM393 datasheet

 

Description :

The LM393 series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages.

Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteris tic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.

Features :

1. Low input biasing current : 25 nA

2. Low input offset current : ±5 nA

3. Maximum offset voltage : ±3 mV

4. Input common-mode voltage range includes ground

5. Differential input voltage range equal to the power supply voltage

6. Low output saturation voltage : 250 mV at 4 mA

MAX992 Datasheet – Rail-to-Rail I/O Comparator

Part Number : MAX992

Function : Low-Voltage, Rail-to-Rail I/O Comparators / 120ns Propagation Delay

Package : SOIC-8 Type

Manufacturers : Maxim Integrated

Pinouts :

MAX992 datasheet

 

Description :

The MAX987 / MAX988 / MAX991 / MAX992 / MAX995 / MAX996 single / dual / quad micropower comparators feature low-voltage operation and rail-to-rail inputs and outputs. Their operating voltage ranges from +2.5V to +5.5V, making them ideal for both 3V and 5V systems.

These comparators also operate with ±1.25V to ±2.75V dual supplies. They consume only 48µA per comparator while achieving a 120ns propagation delay. Input bias current is typically 1.0pA, and input offset voltage is typically 0.5mV. Internal hysteresis ensures clean output switching, even with slow-moving input signals.

Features :

1. 120ns Propagation Delay

2. 48μA Quiescent Supply Current

3. +2.5V to +5.5V Single-Supply Operation

4. Common-Mode Input Voltage Range Extends 250mV Beyond the Rails
