GENERAL DESCRIPTION
The DAC outputs settle within 2.0µs, and the ADC has a 225ksps conversion rate. All devices include an internal reference (2.5V) to provide a well-regulated, low-noise reference for both the ADC and DAC. Programmable reference modes for the ADC and DAC allow the use of an internal reference, an external reference, or a combination of both. FEATURES
such as an internal ±1°C accurate temperature sensor, FIFO, scan modes, programmable internal or external clock modes, data averaging, and AutoShutdown™ allow users to minimize both power consumption and processor requirements. The low glitch energy (4nV●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.
