MAX1102

The MAX1102/MAX1103/MAX1104 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/MAX1103 include an onboard +2V/+4V reference, providing a well-regulated, low noise reference for both the ADC and DAC.

The MAX1104 offers ratiometric conversion, with the reference internally connected to VDD.

The MAX1102/MAX1103/MAX1104 are low-cost, lowpower CODECs for use with microcontrollers (Cs). They allow for greater flexibility when selecting a C. Less expensive Cs without onboard converters can be used while maintaining overall system performance.

The MAX1102 operates from a single +2.7V to +3.6Vsupply, 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 18A standby mode, where both data converters are disabled while the reference remains active, and three shutdown modes: ADC disabled, DAC disabled, and complete shutdown (1A). A quick 10s wake-up time allows all the devices to cycle in and out of shutdown even during short-duration idle times.

They are available in a space-saving 8-pin MAX package.
