When V is selected, V is connected Power-on/Brown-out Reset Protection DD DD internally to the DAC reference circuit. When the V REF Power-Down Modes: pin is used, the user can select the output buffers gain - Disconnects output buffer (High Impedance) to be 1 or 2. When the gain is 2, the V pin voltage REF - Selection of V pull-down resistors OUT should be limited to a maximum of V /2. DD (100 k or 1 k) These devices have an SPI-compatible serial interface. Low Power Consumption: Write commands are supported up to 20 MHz while - Normal operation: <180 A (Single), read commands are supported up to 10 MHz. 380 A (Dual) - Power-down operation: 650 nA typical Applications - EEPROM write cycle (1.9 mA maximum) Set Point or Offset Trimming SPI Interface: Sensor Calibration - Supports 00 and 11 modes Low-Power Portable Instrumentation - Up to 20 MHz writes and 10 MHz reads PC Peripherals - Input buffers support interfacing to Data Acquisition Systems low-voltage digital devices Motor Control Package Types: 10-lead MSOP Extended Temperature Range: -40C to +125C 2015 Microchip Technology Inc.
