19-3053; Rev 2; 5/04 EVAALVUAAILTAIOBNLEKIT 3.5- and 4.5-Digit, Single-Chip ADCs with LCD Drivers MAX1491/MAX1493/MAX1495 General Description The MAX1491/MAX1493/MAX1495 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 nee.

19-3053; Rev 2; 5/04 EVAALVUAAILTAIOBNLEKIT 3.5- and 4.5-Digit, Single-Chip ADCs with LCD Drivers MAX1491/MAX1493/MAX1495 General Description The MAX1491/MAX1493/MAX1495 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. The ADC is configurable for either a ±2V or ±200mV input range and it outputs its conversion results to an LCD. The MAX1491 is a 3.5-digit (±1999 count) device, and the MAX1493/ MAX1495 are 4.5-digit (±19,999 count) devices. The MAX1491/MAX1493/MAX1495 do not require external-precision integrating or auto-zero capacitors, crystal oscillators, charge pumps, or other circuitry required with dual slope ADCs (commonly used in .
