19-1399; Rev 0; 10/98
Single-Supply, Low-Power,
2-Channel, Serial 8-Bit ADCs
General Description
The MAX1108/MAX1109 low-power, 8-bit, dual-channel,
analog-to-digital converters (ADCs) feature an internal
track/hold (T/H) voltage reference, clock, and serial inter-
face. The MAX1108 is specified from +2.7V to +3.6V and
consumes only 105µA. The MAX1109 is specified from
+4.5V to +5.5V and consumes only 130µA. The analog
inputs are software configurable, allowing unipolar/bipolar
and single-ended/differential operation; battery monitor-
ing capability is also included.
The full-scale analog input range is determined by the
internal reference of +2.048V (MAX1108) or +4.096V
(MAX1109), or by an externally applied reference rang-
ing from 1V to VDD. The MAX1108/MAX1109 also feature
a software power-down mode that reduces power con-
sumption to 0.5µA when the device is not in use. The
4-wire serial interface directly connects to SPI™, QSPI™,
and MICROWIRE™ devices without external logic.
Conversions up to 50ksps are performed using either the
internal clock or an external serial-interface clock.
The MAX1108 and MAX1109 are available in a 10-pin
µMAX package with a footprint that is just 20% of an
8-pin plastic DIP.

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.
