MCP4706/4716/4726 8-/10-/12-Bit Voltage Output Digital-to-Analog Converter 2 with EEPROM and I C Interface Features: Package Types Output Voltage Resolutions: MCP4706/16/26 2x2 DFN-6* - 12-bit: MCP4726 SOT-23-6 - 10-bit: MCP4716 V 1 V REF 6 OUT V 6 V 1 OUT REF -8-bit: MCP4706 EP SCL V 2 5 7 SS Rail-to-Rail Output V 2 5 SCL SS Fast Settling Time of 6 s (typical) SDA 3 4 V DD 4 SDA V 3 DD DAC Voltage Reference Options: -V DD * Includes Exposed Thermal Pad (EP) see Table 3-1. -V Pin REF Output Gain Options: Description: - Unity (1x) The MCP4706/4716/4726 are single channel 8-bit, - 2x, only when V pin is used as voltage REF 10-bit, and 12-bit buffered voltage output Digital-to- source Analog Converters (DAC) with nonvolatile memory and 2 Nonvolatile Memory (EEPROM): an I C serial interface. This family will also be referred to as MCP47X6. - Auto Recall of Saved DAC register setting - Auto Recall of Saved Device Configuration The V pin or the device V can be selected as the REF DD (Voltage Reference, Gain, Power-Down) DACs reference voltage. When V is selected, V is DD DD connected internally to the DAC reference circuit. Power-Down modes: When the V pin is used, the user can select the REF - Disconnects output buffer output buffers gain to 1 or 2. When the gain is 2, the - Selection of V pull-down resistors OUT V pin voltage should be limited to a maximum of REF (640 k, 125 k, or 1 k) V /2. DD Low-Power Consumption: The DAC register value and Configuration bits can be - Normal Operation: 210 A typical programmed to nonvolatile memory (EEPROM). The - Power-Down Operation: 60 nA typical nonvolatile memory holds the DAC register and (PD1:PD0 = 11) Configuration bit values when the device is powered Single-Supply Operation: 2.7V to 5.5V off. A device Reset (such as a Power-on Reset) latches 2 I C Interface: these stored values into the volatile memory. - Eight Available Addresses Power-Down modes enable system current reduction - Standard (100 kbps), Fast (400 kbps), and when the DAC output voltage is not required. The V OUT High-Speed (3.4 Mbps) modes pin can be configured to present a low, medium, or high resistance load. Small 6-lead SOT-23 and DFN (2x2) Packages 2 Extended Temperature Range: -40C to +125C These devices have a two-wire I C compatible serial interface for standard (100kHz), fast (400kHz), or High-Speed (3.4 MHz) mode. Applications: These devices are available in small 6-pin SOT-23 and Set Point or Offset Trimming DFN 2x2 mm packages.
