MAXIM MAX1040 MAX1043/MAX1046 MAX1049 handbook(1)
The MAX1040-MAX1049 is an integrated multichannel 10-bit analog-to-digital converter (ADC) and a quad, 10-bit digital-to-analog converter (DAC) in a single IC. The device also includes 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. The devices are guaranteed to operate with a supply volt- age from +2.7V to +3.6V (MAX1041/MAX1043/MAX1047/ MAX1049) and from +4.75V to +5.25V (MAX1040/ MAX1042/MAX1046/MAX1048). These devices consume 2.5mA at 300ksps throughput, only 22µA at 1ksps throughput, and under 0.2µA in the shutdown mode.
