Maxim Integrated MAX1109

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 monitoring 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 ranging from 1V to VDD.

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 interface. The MAX1108 is specified from +2.7V to +3.6V and consumes only 105µA. The MAX1108/MAX1109 also feature a software power-down mode that reduces power consumption 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.
