MCP4921-E/P – 1 Channel12 Bit DAC With SPI Interface IC -DIP-8 Package
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 V REF or 2*V REF 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 (500K 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. Tags, MCP4921 E/P, MCP4921-E/P, 579-MCP4921-E/P.
