Maxim MAX1491/MAX1493/MAX1495 3.5- and 4.5-Digit ADC Datasheet
The MAX1491/MAX1493/MAX1495 family consists of low-power, 3.5- and 4.5-digit analog-to-digital converters (ADCs) featuring integrated liquid crystal display (LCD) drivers. These devices operate from a single 2.7V to 5.25V power supply and include an internal reference, a high-accuracy on-chip oscillator, and a triplexed LCD driver.
Key features of the MAX1491/MAX1493/MAX1495 family include >100dB rejection of 50Hz and 60Hz line noise, selectable input ranges of +2V or +200mV, and continuous internal offset calibration. The devices do not require external precision integrating or auto-zero capacitors, making them suitable for digital panel meters and hand-held multimeters.
