General Description

The MAX1497/MAX1499 low-power, 3.5- and 4.5-digit, analog-to-digital converters (ADCs) with integrated lightemitting diode (LED) 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 multiplexed LED display driver.

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