General Description

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.
