The MAX1106/MAX1107 low-power, 8-bit, single-channel, analog-to-digital converters (ADCs) feature an internal track/hold (T/H), voltage reference, clock, and serial interface. The MAX1106 is specified from +2.7V to +3.6V and consumes only 96μA. The MAX1107 is specified from +4.5V to +5.5V and consumes only 107μA. The analog inputs are pin-configurable, allowing unipolar and single-ended or differential operation.

The full-scale analog input range is determined by the internal reference of +2.048V (MAX1106) or +4.096V (MAX1107), or by an externally applied reference ranging from 1V to V_DD. The MAX1106/MAX1107 also feature a pin-selectable power-down mode that reduces power consumption to 0.5μA when the device is not in use. The 3-wire serial interface directly connects to SPI?, QSPI?, and MICROWIRE? devices without external logic. Conversions up to 25ksps are performed using the internal clock.

The MAX1106/MAX1107 are available in a 10-pin μMAX? package with a footprint that is just 20% of an 8-pin plastic DIP.
