MCP4921 12 Bit Voltage Output Digital to Analog Converter (DAC) with SPI Interface IC DIP-8 Package

The MCP4921 devices are single channel 8-bit, 10-bit and 12-bit buffered voltage output Digital-to-Analog Converters (DACs), respectively. The devices operate from a single 2.7V to 5.5V supply with an SPI compatible Serial Peripheral Interface. The user can configure the full-scale range of the device to be VREF or 2*VREF by setting the gain selection option bit (gain of 1 of 2). The user can shut down the device by setting the Configuration Register bit. In Shutdown mode, most of the internal circuits are turned off for power savings, and the output amplifier is configured to present a known high resistance output load.The devices include double-buffered registers, allowing synchronous updates of the DAC output using the LDAC pin. These devices also incorporate a Power-on Reset (POR) circuit to ensure reliable powerup. The devices utilize a resistive string architecture, with its inherent advantages of low Differential Non-Linearity (DNL) error and fast settling time. These devices are specified over the extended temperature range ( 125°C). The devices provide high accuracy and low noise performance for consumer and industrial applications where calibration or compensation of signals (such as temperature, pressure and humidity) are required. The MCP4921 devices is available in the PDIP, SOIC, MSOP and DFN packages.Features:-MCP4921: 12-Bit Voltage Output DACRail-to-Rail OutputSPI Interface with 20 MHz Clock SupportSimultaneous Latching of the DAC Output with LDAC PinFast Settling Time of 4.5 µsSelectable Unity or 2x Gain OutputExternal Voltage Reference InputExternal Multiplier Mode2.7V to 5.5V Single-Supply OperationExtended Temperature Range: -40°C to 125°CSpecifications:- ParametersSpecificationVDD6.5VAll Inputs and Outputs w.r.t.
