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 V

. 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.
