MAX1042 Datasheet | Maxim Integrated

Description The MAX1040/MAX1042/MAX1046/MAX1048 integrate a multichannel, 10-bit, analog-to-digital converter (ADC) and a quad, 10-bit, digital-to-analog converter (DAC) in a single IC. The devices also include a temperature sensor and configurable general-purpose I/O ports (GPIOs) with a 25MHz SPI™-/QSPI™-/MICROWIRE™-patible serial interface. The ADC is available in a four or an eight input-channel version. The four DAC outputs settle within 2.0µs, and the ADC has a 225ksps conversion rate. All devices include an internal reference (4.096V) providing 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 bination of both. Features such as an internal ±1°C accurate temperature sensor, FIFO, scan modes, programmable internal or external clock modes, data averaging, and Auto Shutdown™ allow users to minimize both power consumption and processor requirements. The low glitch energy (4n V- s) and low digital feedthrough (0.5n V- s) of the integrated quad DACs make these devices ideal for digital control of fastresponse closed-loop systems. The devices are guaranteed to operate with a supply voltage from +4.75V to +5.25V. These devices consume 2.5m A at 225ksps throughput, only 22µA at 1ksps throughput, and under 0.2µA in the shutdown mode. The MAX1042/MAX1048 offer four GPIOs that can be configured as inputs or outputs. The MAX1040/MAX1042/MAX1046/MAX1048 are available in 36-pin thin QFN packages. All devices are specified over the -40°C to +85°C temperature range.
