MAX1109 - Single-Supply / Low-Power / 2-Channel / Serial 8-Bit ADCs

Download the MAX1109 datasheet PDF. This datasheet also covers the MAX1108 variant, as both devices belong to the same single-supply / low-power / 2-channel / serial 8-bit adcs family and are provided as variant models within a single manufacturer datasheet.

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.

Key Features

  • o Single Supply: +2.7V to +3.6V (MAX1108) +4.5V to +5.5V (MAX1109) o Low Power: 105µA at +3V and 50ksps 0.5µA in Power-Down Mode o Software-Configurable Unipolar or Bipolar Inputs o Input Voltage Range: 0 to VDD o Internal Track/Hold o Internal Reference: +2.048V (MAX1108) +4.096V (MAX1109) o Reference Input Range: 1V to VDD o SPI/QSPI/.

19-1399; Rev 1; 6/03 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.
