The AD565ATD falls within the data acquisition category of Digital to Analog Converters (DACs). This device is a high performance, monolithic, 8-bit, current output Digital to Analogue Converter (DAC) designed specifically to meet the requirements of general purpose DACs in the industrial, instrumentation and avionics markets. It is a complete, low cost solution of outstanding performance characteristics over a wide range of system requirements.

The AD565ATD is capable of full 8-bit resolution, providing excellent linearity with better than 0.01% Differential Non-Linearity (DNL), and medium ac pressure response. It comes with a wide range of power supply options to allow for flexibility and is protected from overrange damage conditions.

The device uses the 2-Wire Serial Peripheral Interface (SPI) to provide access to virtually any type of microcontroller within a system. It is designed to be used in a wide variety of applications, including motor control, automotive systems, measurement and control equipment, agricultural and industrial systems and data acquisition systems.

The AD565ATD is designed to provide excellent accuracy and performance in a very small package. It features a low 5-bit digital-to-analog converter (DAC) resolution with ±0.5% full-scale accuracy and a low noise gain of 1.0. Additionally, the device is capable of an abnormally high dynamic speed. With a typical settling time of 8µs for full 8-bit resolution and a maximum throughput of 1MHz, the device enables any required level switching and signal conversion to happen in a short period of time.

Operationally, the AD565ATD works by receiving a voltage reference input and converting it into a precise current output. This output is on the order of a few microamps and is managed by a built-in Programmable Gain Amplifier (PGA). The PGA amplifies the DAC output current, allowing a low current logic input to be amplified to a precise output current. The PGA can be programmed using the logic inputs, allowing the user to select the desired gain level.

In summary, the AD565ATD is a monolithic, 8-bit, current output Digital to Analog Converter (DAC) designed specifically to meet the requirements of general purpose DACs in the industrial, instrumentation and avionics markets. It is designed to provide excellent accuracy and performance in a very small package, while its 2-Wire Serial Peripheral Interface (SPI) provides access to virtually any type of microcontroller within a system. Additionally, it works by receiving a voltage reference input and converting it into a precise current output, which is managed by a built-in Programmable Gain Amplifier (PGA).
