The MCP4801-E/P is a low cost, low power, 8-bit digital-to-analog converter (DAC) that is well suited for use in data acquisition and control applications. It is available in single and dual channel versions, making it ideal for multi-channel systems. The device features a typical 8-bit (256 step) resolution and a broad operating range of 5 V to 15 V. It is designed to operate from either a single 5 V supply or dual ±5 V supplies.

The MCP4801-E/P has two DAC outputs, an analog output (OUTA) and a buffered DAC output (OUTB). The analog output has a low output impedance and is capable of sourcing more than 5 mA of current while the buffered output is capable of sourcing more than 10 mA of current. The outputs have a typical full-scale output of 2.5 V, when powered from a 5 V supply, but can swing up to 15 V when powered from dual ±5 V supplies. The bipolar voltage reference input (VREF) provides a buffered reference voltage to the device and can be used to trim the full-scale output voltage.

The device also includes a power-down feature which allows the device to be powered down without disconnecting power from the VDD, VR and VSS pins. This allows for efficient use of power and also removes any residual noise from the output when the device is not in use.

In addition to the DAC outputs, the device also features a temperature sensor output which measures the temperature of the device. This is useful for monitoring the temperature of the device, avoiding any potential performance degradation due to over-heating. The device can be programmed to operate in either normal mode or shutdown mode. In normal mode, the device operates with a nominal voltage over the specified range and can source up to 10 mA of current and sink up to 5 mA of current. In shutdown mode, the device reduces its power consumption and output impedance by 0.3 % of the specified voltage range, making it suitable for low-power and low-noise applications.

The MCP4801-E/P can be used in a variety of data acquisition and control applications, where accurate voltage control is required. Its high power output, low power consumption and small size make it ideal for applications such as motor control, automated test equipment, process control and position control systems, as well as communications and power systems.

The device’s versatile input voltage range, low power consumption and buffered reference voltage make it well suited for applications where precise control of the output voltage is critical. It can be used to accurately control the voltage output of a system and can be used to provide precise voltage control over temperature, power and load variations.

The MCP4801-E/P is a low cost, low power, 8-bit Digital-to-Analog Converter that is ideal for use in data acquisition and control applications. It is designed to operate over a wide voltage range, providing excellent accuracy and linearity even at high resolution values. Its low power consumption, wide dynamic range and temperature output make it a great choice for applications requiring precise voltage control.
