8-Bit CODECs
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-regulat-
ed, low noise reference for both the ADC and DAC.
The MAX1104 offers ratiometric conversion, with the
reference internally connected to V
DD
.
The MAX1102/MAX1103/MAX1104 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 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
V
DD
monitor in addition to AIN for power supply moni-
toring. All devices feature a low 18µA standby mode,
where both data converters are disabled while the ref-
erence 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.
