5-Digit, Single-Chip ADCs with LCD Drivers 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.
The ADCs are configurable for either a ±2V or ±200mV input range and outputs its conversion results to an LCD and/or to a microcontroller (µC).
