MAX1021
Overview
The MAX1021/MAX1043 integrate a multichannel, 10-bit, analog-to-digital converter (ADC) and a 10-bit, digital-toanalog converter (DAC) in a single IC. The devices also include a temperature sensor and configurable generalpurpose I/O ports (GPIOs) with a 25MHz SPI™-/QSPI™-/ MICROWIRE™-compatible serial interface.
- s) and low digital feedthrough (0.5nV
- s) of the integrated DACs make these devices ideal for digital control of fast-response closed-loop systems. The devices are guaranteed to operate with a supply voltage from +2.7V to +5.25V. They consume 2.5mA at 225ksps throughput, only 22µA at 1ksps throughput, and under 0.2µA in the shutdown mode. The MAX1021/ MAX1043 offer four GPIOs that can be configured as inputs or outputs. The MAX1021/MAX1043 are available in 36-pin thin QFN packages. These devices are specified over the -40°C to +85°C temperature range. Features
