The AD667KP is a high-performance Digital to Analog Converter (DAC) designed to meet a wide range of data acquisition requirements, from low-frequency, low-power applications to high-frequency, high-performance systems. The DAC is designed to achieve high speed, low power, and high linearity performance by utilizing a 55MHz 6-bit digital input. With its low power mode, it is capable of working up to 12-bits in a wide supply voltage range from 3.3V to 6V.

The AD667KP DAC features an 8-bit output resolution, with extended 12-bit resolution in low power mode. It can generate an extendable output voltage range of 0.1V to 4.095V at up to 55MHz. The DAC has an offset range of 0-2V, and an offset drift of 0.03V per °C temperature change. It supports low update rates of up to 20 million conversions per second, with a maximum signal-to-noise-and-distortion (S/N + D) ratio of 93dB. The device also features glitch-free output, linearity of 0.02% over an extended temperature range (– 40°C to + 85°C), and ±0.1% output accuracy over the full operating temperature range.

The AD667KP DAC is ideal for applications such as power systems, signal processing, audio, data acquisition, and communications. It is designed for use in a variety of signal conditioning and control applications, including digital power metering and control, motor control and monitoring, video interface, data acquisition, and process automation.

The working principle of the AD667KP DAC is based on a differential architecture that utilizes an internal amplifier to convert digital inputs into analog outputs. At each input logic transition, the internal amplifier converts the digital input into an analog output. The output of the DAC is then amplified and filtered to produce a stable analog output voltage. The DAC can be programmed to produce various analog output range values, including 0-10V, 0-20V, 0-30V, and even 0-2V. In addition, the DAC can be used to control various external loads such as motors, transistors, relays, and sensors.

In conclusion, the AD667KP is a high-performance Digital to Analog Converter (DAC) designed to provide high speed, low power, and high linearity performance. Its extended 12-bit resolution in low power mode and wide supply voltage range make it useful for a variety of applications. It is designed for use in signal conditioning and control applications, including power systems, motor control and monitoring, video interface, data acquisition, and process automation.
