Description
The MAX1102/MAX1103/MAX1104 are low-cost, low-power CODECs for use with microcontrollers (µCs). They allow for greater flexibility when selecting µC. Less expensive µCs without onboard converters can be used while maintaining overall system performance.
The MAX1102 operates from a single +2.7V to +3.6V supply, the MAX1103 operates from a +4.5V to +5.5V supply, and the MAX1104 operates from a +2.7V to +5.5V supply. The MAX1102/MAX1103 incorporate a VDD monitor in addition to AIN for power supply monitoring. All devices feature a low 18µA standby mode, where both data converters are disabled while the reference remains active, and three shutdown modes: ADC disabled, DAC disabled, and complete shutdown (1µA). A quick 10µs wake-up time allows the MAX1102/MAX1103/MAX1104 to cycle in and out of shutdown even during short-duration idle times.
The MAX1102/MAX1103/MAX1104 are available in a space-saving 8-pin µMAX® package.
