AD7391SRZ is a single channel 9-bit resolution data acquisition device integrated with a digital-to-analog converter (DAC). The AD7391SRZ is built on the latest CMOS process and offers superior performance in terms of linearity, noise and low power consumption. It features a low output impedance (1 ohm typ) coupled with a 9-bit resolution, which allows it to accurately reproduce digital signals. The AD7391SRZ is ideal for a wide range of applications including digital-to-analog conversion, motion control, medical imaging, audio devices, and test and measurement. Additionally, the device is suitable for use in low-voltage, battery-powered tool and module applications.

The AD7391SRZ digital-to-analog converter utilizes a simple voltage-to-current architecture. The device operates with a supply voltage of 2.7 to 5.5 volts and a minimum temperature range of -40 to +85 degrees Celsius. It features a single-ended output current that is controlled by a 9-bit input code. The output current of the AD7391SRZ can be either positive or negative, depending on the sign bit of the input code. The AD7391SRZ is capable of generating up to 7.84mA output current at the full 9-bit resolution. This allows for precise analog signal generation, even in difficult voltage environments.

The AD7391SRZ also features an integrated programmable gain amplifier to match the output current to a user’s specific application. This internal amplifier is adjustable from 0.3V/V to 5V/V allowing customers to tailor the gain to suit their individual requirements. Additionally, the device also features an integrated low-noise voltage regulator to ensure consistent performance over temperature, supply voltage, and time.

The AD7391SRZ is available with a range of package options depending on the specific application, including single channel with and without bypass, three and eight channel, as well as differential and single-ended voltage output packages. This allows customers to select a package that best suits their needs and helps to minimize the cost of design, manufacturing and test. Additionally, an onboard power-down control is offered, allowing the device to be disabled when not in use, thus saving power and increasing system efficiency.

In summary, the AD7391SRZ is an ideal choice for a high performance, low power consumption 9-bit resolution digital-to-analog converter. The device is highly flexible and offers integrated features such as a programmable gain amplifier and an onboard power down mode. It is also available in a wide range of packages, making it well suited to a variety of different applications.
