MAX1108/MAX1109
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 interface.
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 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.
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 ...
