Codec General Purpose 1-CH 8bit 3.3V 8-Pin uMAX

The MAX1102 CODECs provide both an 8-bit analog-to-digital converter (ADC) and an 8-bit digital-to-analog converter (DAC) with a 4-wire logic interface. The MAX1102 include an onboard +2V reference, providing a well-regulated, low noise reference for both the ADC and DAC. The MAX1102 are low-cost, low power CODECs for use with microcontrollers (µCs). They allow for greater flexibility when selecting a 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 MAX1102 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 to cycle in and out of shutdown even during short-duration idle times. The MAX1102 is available in a space-saving 8-pin µMAX package.
