The VREF pin, the device VDD or the internal band gap voltage can be selected as the DAC’s reference voltage. When VDD is selected, VDD is connected internally to the DAC reference circuit. When the VREF pin is used, the user can select the output buffer’s gain to be 1 or 2. When the gain is 2, the VREF pin voltage should be limited to a maximum of VDD/2. These devices have an SPI-compatible serial interface. Write commands are supported up to 20 MHz while read commands are supported up to 10 MHz. Applications • Set Point or Offset Trimming • Sensor Calibration • Low-Power Portable Instrumentation • PC Peripherals • Data Acquisition Systems • Motor Control Note 1: Associated with both DAC0 and DAC1 Dual Single MCP48FEBx2 MSOP MCP48FEBx1 1 2 3 4 7 8 9 10 VSS VOUT0 VREF0 CS VDD SCK SDI SDO 56 LAT0/HVC NC MSOP 1 2 3 4 7 8 9 10 VSS VOUT0 VREF (1) CS VDD SCK SDI SDO 5 6 LAT0/HVC (1) VOUT1 8-/10-/12-Bit Single/Dual Voltage Output Nonvolatile Digital-to-Analog Converters with SPI Interface |
