Product Descriptions

The MCP4901/4911/4921 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 (500 k ohm typical). 

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 power up. 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 MCP4901/4911/4921 devices are 

available in the PDIP, SOIC, MSOP and DFN packages.
