MCP47FEB02A0-E/ST

MCP47FEB02A0-E/ST is an 8bit dual voltage output nonvolatile digital-to-analog converter with I²C™ interface and nonvolatile memory. The VREF pin, the device VDD, or the internal bandgap 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. The application includes set point or offset trimming, sensor calibration, low-power portable instrumentation, PC peripherals, data acquisition systems, and motor control.

• Supply voltage range from 2.7 to 5.5V (VDD = 5.5V, TA = +25°C)
• I2C control interface, 7Fh DAC output POR/BOR setting
• 1 number of VREF input, internal band gap, EEPROM memory
• Device VDD, external VREF pin (buffered or unbuffered), internal band gap
• Unity (1x), 2x (when not using internal VDD as voltage source)
• User-programmed Power-on Reset/Brown-out Reset output setting recall and device configuration bits
• Auto recall of saved DAC register setting
• Power-on/brown-out reset protection
• Nonvolatile memory write protect (active-low WP) bit
• 8 pin TSSOP package, extended operating temperature range from -40 to 125°C
