10-Bit, Multichannel ADCs/DACs with FIFO, Temperature Sensing, and GPIO Ports
General Description
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 inputchannel 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.
