The AD5681RBCPZ-1RL7 is a 12-bit digital-to-analog converter (DAC) that accurately converts digital code inputs into analog signals. Designed for low power consumption and optimized for low noise and high-resolution applications, the AD5681RBCPZ-1RL7 is an ideal choice for precision data conversion. It is available in an 8-lead SOIC package with an operating temperature range of −40°C to +105°C.

Application Field

The AD5681RBCPZ-1RL7 is well suited for applications requiring performance and accuracy, such as industrial, consumer, instrumentation, medical, test and measurement, communications, and multimedia. Typical applications include remote controls, smart meters, sensors and actuators, interactive displays, medical imaging, touch screens, digital audio systems, programmable voltage and current sources, and video systems. In industrial control applications, the AD5681RBCPZ-1RL7 can generate variable voltage signals for industrial high-voltage power supplies, variable current signals for welding, variable resistance signals for gas pressure and flow controlling, variable speed signals for speed controlling of grinders and motors, and variable temperature signals for temperature controlling of ovens. It can also be used in energy-saving light control systems and electro-acoustic systems for real-time timing and volume control.

Working Principle

The AD5681RBCPZ-1RL7 is based on the R-2R resistor ladder topology, which is a widely used type of DAC circuit. It uses a series of weighted resistors along the ladder and produces an analog voltage output as a function of the digital code input. This can be expressed mathematically as VOUT = k∑i=0nDi2i, where k is a scaling factor and Di is the ith bit of the digital code. The AD5681RBCPZ-1RL7 offers a low nonlinearity of only ±1.25 LSB max over the full-scale range and fast settling time of 15 μs.

The AD5681RBCPZ-1RL7 is powered by a single 3.0 V to 3.6 V power supply and is available in a space-saving 8-lead SOIC package. Features include a fast 12-bit settling time of 15 μs, a low power consumption of 33 mW, and a low nonlinearity of ±1.25 LSB max over the full scale range. Its high-accuracy conversion and fast settling time make it ideal for applications requiring fast and accurate data conversion.
