MAX14979EETX+ - Brand New Maxim Integrated Analog Switches / Multiplexers
-
Description
The MAX1497/MAX1499 are low-power, 3.5- and 4.5-digit, analog-to-digital converters (ADCs) with an integrated light-emitting diode(LED) driver for digital panel meters, handheld meters, digital voltmeters, and digital multimeters. The devices are operated on a single 2.7V to 5.25V power supply, with an internal reference, a high-accuracy on-chip oscillator, and a multiplexed LED display driver. The ADC is configurable for either a ±2V or ±200mV input range, and it outputs its conversion results to an LED and/or to a microcontroller.
