The MAX5316 is a high-accuracy, 16-bit, serial SPI input, buffered voltage output digital-to-analog converter (DAC) in a 4mm x 5mm, 24-lead TQFN package. The device features ±1 LSB INL (max) accuracy and a ±0.25 LSB DNL (typ) accuracy over the temperature range of -40°C to +105°C.The DAC voltage output is buffered with a fast settling time of 3µs and a low offset and gain drift of ±0.6ppm/°C of FSR (typ). The force-sense output (OUT) maintains accuracy while driving loads with long lead lengths. A separate AVSS supply is provided to permit the output amplifier to go to 0V (GND) to maintain full linearity performance near ground.At power-up, the device resets its outputs to zero or midscale.The wide 2.7V to 5.5V supply voltage range and integrated low-drift, low-noise reference buffer make for ease of use. The MAX5316 features a 50MHz 3-wire SPI interface. For an I²C interface, use the MAX5317.The MAX5316 is available in a 24-lead TQFN-EP package and operates over the -40°C to +105°C temperature range.ApplicationsAutomatic CalibrationAutomatic Test EquipmentCommunication SystemsData-Acquisition SystemsGain and Offset AdjustmentMedical EquipmentProcess Control and Servo LoopsProgrammable Voltage and Current SourcesTest and Measurement

The MAX533 serial-input, voltage-output, 8-bit quad digital-to-analog converter (DAC) operates from a sin-gle +2.7V to +3.6V supply. Internal precision buffers swing rail to rail, and the reference input range includes both ground and the positive rail. The MAX533 features a 1µA shutdown mode.The serial interface is double buffered: a 12-bit input shift register is followed by four 8-bit buffer registers and four 8-bit DAC registers. The 12-bit serial word consists of eight data bits and four control bits (for DAC selection and special programming commands). Both the input and DAC registers can be updated indepen-dently or simultaneously with a single software com-mand. Two additional asynchronous control pins, active-low LDAC and active-low CLR, provide simultaneous updating or clearing of the input and DAC registers.The interface is compatible with SPI™, QSPI™ (CPOL = CPHA = 0 or CPOL = CPHA = 1), and Microwire™. A buffered data output allows daisy chaining of serial devices.In addition to 16-pin DIP and CERDIP packages, the MAX533 is available in a 16-pin QSOP that occupies the same area as an 8-pin SO.ApplicationsDigital Gain and Offset ControlPortable InstrumentationProgrammable AttenuatorsProgrammable Current Sources

The MAX534 serial-input, voltage-output, 8-bit quad digital-to-analog converter (DAC) operates from a single +4.5V to +5.5V supply. Internal precision buffers swing rail to rail, and the reference input range includes both ground and the positive rail. The MAX534 features a 2.5µA shutdown mode.The serial interface is double buffered: a 12-bit input shift register is followed by four 8-bit buffer registers and four 8-bit DAC registers. The 12-bit serial word consists of eight data bits and four control bits (for DAC selection and special programming commands). Both the input and DAC registers can be updated independently or simultaneously with a single software command. Two additional asynchronous control pins, active-low LDAC and active-low CLR, provide simultaneous updating or clearing of the input and DAC registers.The interface is compatible with SPI™, QSPI™ (CPOL = CPHA = 0 or CPOL = CPHA = 1), and MICROWIRE™. A buffered data output allows daisy chaining of serial devices.In addition to 16-pin DIP and CERDIP packages, the MAX534 is available in a 16-pin QSOP that occupies the same area as an 8-pin SO.For operation guaranteed to 2.7V, see the MAX533 data sheet.ApplicationsDigital Gain and Offset ControlPortable InstrumentationProgrammable AttenuatorsProgrammable Current Sources
