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 105A. The MAX1109 is specified from
+4.5V to +5.5V and consumes only 130A. 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 0.5A 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
MAX package with a footprint that is just 20% of an
8-pin plastic DIP.
