The MCP47FEB01A1-E/ST is a monolithic CMOS voltage output Digital to Analog Converter (DAC). It offers precision, flexibility, and excellent ac and dc performance. This device is available in five different packages, giving users the flexibility to choose the best size and type of output for their application.

MCP47FEB01A1-E/ST’s application field includes powering pre-amps, controlling motor current or positioning, adjusting sound levels, setting current limit in battery chargers, providing references for LCD displays, calibrating SAR ADCs, voltage-controlled audio devices, and more. With its high resolution, low offset voltage and low noise, these devices guarantee precise operations.

The DACs are ideal for applications that require high-precision current or voltage control, especially for those requiring very precise calibrations. The devices deliver smooth and precise output independent of its load or temperature. Besides, these devices allow for precise set-point settings without needing an external power supply.

The core of the MCP47FEB01A1-E/ST is a highly-accurate, low-step (1 LSB) 8-bit DAC with a differential nonlinearity of 1/2 LSB. The on-chip conversion time is also very short: its input latch captures data at 6 nanoseconds and its output conversion time is 25 nanoseconds.

This device operates in combination with the powering MCU, but can also be programmed by other sources, such as an I2C or SPI master. The MCP47FEB01A1-E/ST is controlled via a 3-wire or 2-wire serial interface. With a reset pin, the outputs can be initialized in a known state upon powering up or resetting the device. Upon powering up, the outputs can be optimized for low-current consumption or for low-output noise.

The MCP47FEB01A1-E/ST functions as an 8-bit DAC, which means it takes 8 bits of digital input and converts them into an analog voltage output. Eight data pins are connected to the MCU by means of three-wire or two-wire serial interface, while an additional reset pin is connected to the MCU. When the device is powered up, it sets the output voltage to its smallest level, then sequentially increases it until all 8 bits have been read in. This process of converting digital output to an analog voltage is done by way of a R-2R network that sequentially adds or removes current from the output pins. In the case of the MCP47FEB01A1-E/ST, the current at each output pin is 1 mA.

The MCP47FEB01A1-E/ST provides superior accuracy with low-noise performance and low-offset voltage. It also operates over a wide temperature range, from -40°C to +85°C. This makes it suitable for both laboratory and industrial applications.

The MCP47FEB01A1-E/ST is an ideal solution for applications that demand precise control of voltage or current, offering superior accuracy and precision. Its features along with its simple and fast programming make it the perfect solution for powering pre-amps, controlling motor current or positioning, setting current limit in battery chargers, providing references for LCD displays, calibrating SAR ADCs, and many other applications.
