The MAX5713/MAX5714/MAX5715 4-channel, low-power, 8-/10-/12-bit, voltage-output digital-to-analog converters (DACs) include output buffers and an internal reference that is selectable to be 2.048V, 2.500V, or 4.096V. The MAX5713/MAX5714/MAX5715 accept a wide supply voltage range of 2.7V to 5.5V with extremely low power (3mW) consumption to accommodate most low-voltage applications. A precision external reference input allows rail-to-rail operation and presents a 100kΩ (typ) load to an external reference.The MAX5713/MAX5714/MAX5715 have a 50MHz 3-wire SPI/QSPI™/MICROWIRE®/DSP-compatible serial interface that also includes an active-low RDY output for daisy-chain applications. The DAC output is buffered and has a low supply current of less than 250µA per channel and a low offset error of ±0.5mV (typ). On power-up, the MAX5713/MAX5714/MAX5715 reset the DAC outputs to zero, providing additional safety for applications that drive valves or other transducers which need to be off on power-up. The internal reference is initially powered down to allow use of an external reference. The MAX5713/MAX5714/MAX5715 allow simultaneous output updates using software LOAD commands or the hardware load DAC logic input (active-low LDAC).A clear logic input (active-low CLR) allows the contents of the CODE and the DAC registers to be cleared asynchronously and sets the DAC outputs to zero. The MAX5713/MAX5714/MAX5715 are available in a 14-pin TSSOP and an ultra-small, 12-bump WLP package and are specified over the -40°C to +125°C temperature range.ApplicationsAutomatic TuningCommunication SystemsData AcquisitionGain and Offset AdjustmentsPortable InstrumentationPower Amplifier ControlsProcess Control and Servo LoopsProgrammable Voltage and Current Sources

The MAX5717 and MAX5719 are serial-input, unbuffered 16 and 20-bit voltage-output unipolar digital-to-analog converters (DACs) with integrated feedback resistors that allow bipolar operation when used with an external operational amplifier. These DACs provide low glitch energy, low noise, tight bipolar resistor matching, and high accuracy. The DACs feature 1LSB INL (max, MAX5717A) over the temperature range of -40°C to +105°C. Integrated precision setting resistors make the DACs easy to use. The MAX5717 and MAX5719 feature a 50MHz, 3-wire SPI™, QSPI™, MICROWIRE™, and DSP-compatible serial interface.On power-up, the output resets to zero-scale, providing additional safety for applications which drive valves or other transducers that need to be off on power-up. The DAC output settles in 750ns and has a low offset and gain drift of ±0.1 ppm/°C of FSR.The MAX5717 is functionally similar to the MAX542, but with significantly faster settling time. The MAX5719 provides a similar speed improvement as well as an increase in resolution to 20 bits.ApplicationsAutomatic Test EquipmentAutomatic TuningCommunication SystemsData-Acquisition SystemsGain and Offset AdjustmentPortable InstrumentationProcess Control and Servo LoopsProgrammable Voltage and Current SourcesTest and Measurement Equipment
