Description

The MAX1340MAX1343/MAX1346MAX1349 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 inputchannel version. The four DAC outputs settle within 2.0µs, and the ADC has a 300ksps conversion rate.

The MAX1340MAX1343/MAX1346MAX1349 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 fastresponse closed-loop systems.

The devices are guaranteed to operate with a supply voltage from +2.7V to +3.6V (MAX1341/MAX1343/MAX1347/ MAX1349) and from +4.5V to +5.5V (MAX1340/MAX1342/ MAX1346/MAX1348). The devices consume 2.5mA at 300ksps throughput, only 22µA at 1ksps throughput, and under 0.2µA in the shutdown mode. The MAX1342/ MAX1343/MAX1348/MAX1349 offer four GPIOs that can be configured as inputs or outputs.

The MAX1340MAX1343/MAX1346MAX1349 are available in 36-pin thin QFN packages. All devices are specified over the -40°C to +85°C temperature range.
