MAX1492 Datasheet Single-chip Adcs

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX1492/MAX1494 19-2959; Rev 4; 7/10 EVAALVUAAILTAIOBNLEKIT 3.5- and 4.

General Description

The MAX1492/MAX1494 low-power, 3.5- and 4.5-digit, analog-to-digital converters (ADCs) with integrated liquid crystal display (LCD) drivers operate from a single 2.7V to 5.25V power supply.

They include an internal reference, a high-accuracy on-chip oscillator, and a triplexed LCD driver.

An internal charge pump generates the negative supply needed to power the integrated input buffer for single-supply operation.

Key Features

  • include data hold and peak hold, overrange and underrange detection, and a lowbattery monitor. The MAX1494 comes in a 32-pin, 7mm x 7mm LQFP package, and the MAX1492 comes in 28-pin SSOP and 28-pin PDIP packages. All devices in this family operate over the 0°C to +70°C commercial temperature range. Digital Panel Meters Hand-Held Meters Digital Voltmeters Digital Multimeters.
