19-3280; Rev 2; 8/04 KIT ATION EVALU E L B AVAILA 10-Bit, Multichannel ADCs/DACs with FIFO, Temperature Sensing, and GPIO Ports General Description The MAX1020–MAX1023/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 inputchannel versions. The octal DAC outputs settle within 2.0µs, and the ADC has a 300ksps 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 (MAX1021/MAX1023/MAX1057) and from +4.75V to +5.25V (MAX1020/MAX1022/ MAX1058). The devices consume 2.5mA at 300ksps throughput, only 22µA at 1ksps throughput, and under 0.2µA in the shutdown mode. The MAX1057/MAX1058 feature 12 GPIOs, while the MAX1020/MAX1021 offer 4 GPIOs that can be configured as inputs or outputs. The MAX1057/MAX1058 are available in 48-pin thin QFN packages. The MAX1020–MAX1023 are available in 36pin thin QFN packages. All devices are specified over the -40°C to +85°C temperature range.
