MAX542BCSD+

The MAX542BCSD+ is a +5V, serial input, voltage output 16bit digital to analogue converter (DAC) in 14 pin NSOIC package. The device operates from single +5V supply and provides 16bit performance (±2LSB INL and ±1LSB DNL) over temperature without any adjustments. The unbuffered output of DAC results in low supply current of 0.3mA and low offset error of 1LSB. The DAC output range is 0V to VREF and 16bit serial word is used to load data into DAC latch. The 10MHz, 3-wire serial interface is compatible with SPI/QSPI/MICROWIRE and it interfaces directly with optocouplers for applications requiring isolation. For bipolar operation, matched scaling resistors are provided in MAX542B for use with an external precision op amp (such as the MAX400) which generates a ±VREF output swing. It is used in high resolution offset and gain adjustment, industrial process control, automated test equipments and data acquisition systems.

• Supply voltage range from 4.75V to 5.25V, operating temperature range from 0°C to 70°C
• A power-on reset circuit clears DAC output to 0V (unipolar mode) when power is initially applied
• Low power of 1.5mW, gain error of ±5LSB and zero code offset error of ±1lSB at TA = +25°C
• Output settling time of 1μs, positive supply current of 0.3mA
• Voltage output slew rate of 25V/μs at CL = 10pF
• Reference -3dB bandwidth of 1MHz
• Power supply rejection (PSR) of ±1LSB at 4.75V ≤ VDD ≤ 5.25V
• Unbuffered voltage output directly drives 60Kohm loads
• Schmitt trigger inputs for direct optocoupler interface
• Kelvin sense connections for reference and analogue ground pins to reduce layout sensitivity
