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 VDD.
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
VDD 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(VDD = +2.7V to +3.6V (MAX1102), VDD = +4.5V to +5.5V (MAX1103), VDD = +2.7V to +5.5V (MAX1104), fSCLK = 6.0MHz (50% duty
cycle), ROUT = 10k, COUT = 100pF, TA = TMIN to TMAX. Typical values are at TA = +25°C, unless otherwise noted.)
