MAXIM MAX1040 MAX1043/MAX1046 MAX1049 handbook
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, also including 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 proces- sor 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.
