MAX1499 - Single-Chip ADCs

Download the MAX1499 datasheet PDF. This datasheet also covers the MAX1497 variant, as both devices belong to the same single-chip adcs family and are provided as variant models within a single manufacturer datasheet.

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.

MAX1497/MAX1499 19-3054; Rev 0; 11/03 3.5- and 4.5-Digit, Single-Chip ADCs with LED Drivers and µC Interface 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. 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 (µC). µC communication is possible through an SPI™-/QSPI™-/MICROWIRE™compatible serial interface.
