Working Principle of DAC7512N/250

The DAC7512N/250 is based on Voltage-Output Digital-to-Analog Converter (VOTDAC) technology, which is designed to be highly accurate and tolerant to noise. The chip contains a high-performance, low-power CMOS DAC circuit that can convert 8-bit digital information into an analog voltage.

The key to this device’s low-power operation is the precision voltage-output DAC architecture. In addition to providing high-accuracy output voltage, this architecture also reduces power consumption by using a form of pulse-width modulation (PWM) to reduce static power consumption. The PWM utilizes an internal clock signal to reduce the static current to only 25 μA.

The DAC7512N/250 can be used as both a unipolar or bipolar output depending on the input data format. In unipolar mode, the chip produces a 0-5 V output. When used in bipolar mode, the output can range from -2.5 to +2.5 V.

The DAC7512N/250 is ideal for applications requiring the accurate reproduction of analog signals.It offers high accuracy and low power consumption, making it a great choice for industrial, consumer and test applications.
