MAX1042BETX+T

The MAX1040–MAX1043/MAX1046–MAX1049 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™-compatible serial interface.
The ADC is available in a 4 or an 8 input-channel version.
The four 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 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 quad DACs make these devices ideal for digital control of fast response closed-loop systems.
