MAX1346BETX General Description

The MAX1340/MAX1342/MAX1346/MAX1348 integrate a multichannel, 12-bit, analog-to-digital converter (ADC) and a quad, 12-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 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 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 voltage from +4.75V to +5.25V The devices consume 2.5mA at 225ksps throughput, only 22μA at 1kspsthroughput, and under 0.2μA in the shutdown mode. The MAX1342/MAX1348 offer four GPIOs that can be configured as inputs or outputs.The MAX1340/MAX1342/MAX1346/MAX1348 are available in 36-pin thin QFN packages. All devices are specified over the -40°C to +85°C temperature range.
