The MAX1020/MAX1022/MAX1057/MAX1058 integrate a multichannel, 10-bit, analog-to-digital converter (ADC) and an octal, 10-bit, digital-to-analog converter (DAC) in a single IC. These devices also include a temperature sensor and configurable general-purpose I/O ports (GPIOs) with a 25MHz SPI-/QSPI™-/MICROWIRE®-compatible serial interface. The ADC is available in 8/12/16 input-channel versions. The octal DAC outputs settle within 2.0µs, and the ADC has a 225ksps conversion rate.
All devices include an internal reference (2.5V or 4.096V) providing a well-regulated, low-noise reference for both the ADC and DAC. Programmable reference modes for the ADC and the 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 octal 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 +3.6V (MAX1057) and from +4.75V to +5.25V (MAX1020/MAX1022/MAX1058). The devices consume 2.5mA at 225ksps throughput, only 22µA at 1ksps throughput, and under 0.2µA in the shutdown mode. The MAX1057/MAX1058 feature 12 GPIOs, while the MAX1020 offers four GPIOs that can be configured as inputs or outputs.
The MAX1057/MAX1058 are available in 48-pin thin QFN packages. The MAX1020/MAX1022 are available in 36- pin thin QFN packages. All devices are specified over the -40°C to +85°C temperature range.
