DS20005405A-page 1 MCP47FVBXX Features • Operating Voltage Range: - 2.7V to 5.5V – Full Specifications - 1.8V to 2.7V – Reduced Device Specifications • Output Voltage Resolutions: - 8-bit: MCP47FVB0X (256 Steps) - 10-bit: MCP47FVB1X (1024 Steps) - 12-bit: MCP47FVB2X (4096 Steps) • Rail-to-Rail Output • Fast Settling Time of 6 µs (typical) • DAC Voltage Reference Source Options: - Device VDD -External VREF pin (buffered or unbuffered) - Internal Band Gap (1.22V typical) • Output Gain Options: -(1x) Unity - 2x (when not using internal VDD as voltage source) • Power-on/Brown-out Reset Protection • Power-Down Modes: - Disconnects output buffer (High Impedance) - Selection of VOUT pull-down resistors (100 k or 1 k) • Low Power Consumption: - Normal operation: <180 µA (Single), 380 µA (Dual) - Power-down operation: 650 nA typical •I2C™ Interface: - Slave address options: four predefined addresses - Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) modes - High Voltage Command Support (MCP47FEBXX compatibility) • Package Types: 8-lead TSSOP • Extended Temperature Range: -40°C to +125°C Package Types General Description The MCP47FVBXX are Single- and Dual-channel 8-bit, 10-bit, and 12-bit buffered voltage output Digital-to- Analog Converters (DAC) with volatile memory and an I2C serial interface. 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 a two-wire I2C-compatible serial interface for Standard (100 kHz), Fast (400 kHz) or High-Speed (1.7 MHz and 3.4 MHz) modes. Applications • Set Point or Offset Trimming • Sensor Calibration • Low-Power Portable Instrumentation • PC Peripherals • Data Acquisition Systems • Motor Control MCP47FVBX1 TSSOP Single VOUT0 VREF0 NC SCL LAT0/HVC 1 2 3 4 8 7 6 5 VSS SDA VDD MCP47FVBX2 TSSOP Dual VOUT0 VREF(1) VOUT1 SCL LAT(1)/HVC 1 2 3 4 8 7 6 5 VSS SDA VDD Note 1: This pin’s signal can be connected to DAC0 and/or DAC1. 8- /10- /12-Bit Single/Dual Voltage Output Volatile Digital-to-Analog Converters with I ²C™ Interface |
