The AD9778ABSVZ is a highly accurate 8-channel digital-to-analog converter (DAC) with a selectable output resolution of 8, 10, 12, and 16 bits. It is the ideal choice in multi-output data systems where precision, accuracy and a reduced number of components are crucial requirements. The AD9778ABSVZ provides high-resolution accuracy in a wide range of applications including data acquisition, industrial and measurement systems, as well as automated test equipment.

The AD9778ABSVZ features 8 parallel current-steering outputs, each with an independent reference and temperature compensation. It has a full-scale output range from ±1 mA up to ±20 mA and is capable of driving up to 32 loads with the use of external buffer amplifiers. Additionally, the AD9778ABSVZ features fast settling times with monotonic settling to within 0.2% of full-scale output. The device is also power efficient and consumes only 20 mW of power.

The AD9778ABSVZ is capable of meeting the accuracy requirements of many industrial and consumer applications such as 3d printing, factory automation, process control, communications, audio systems and motor drives. It has a power supply range from ±2.7 V to ±7 V, industry standard pin-out and a full complement of standard bus interfaces for easy integration into any system.

In terms of its operating principle, the AD9778ABSVZ uses a high-precision current-steering analog circuit to take a digital input word, convert the word into the physical voltage times current values and control the magnitude of the output current. The internal chip design is optimized to provide high performance and true monotonicity. The output of the AD9778ABSVZ is programmable, either by digital or analog means, with 28 settings to optimize the response of the output voltage versus current waveforms. It has a wide variation in output resistances, allowing the user to select different settings at different frequencies.

The AD9778ABSVZ simplifies the design process for multichannel output systems with its integrated power supply, reference and control logic circuits, providing designers with a single-chip solution for replacing multiple components. Its seamless operation and outstanding accuracy make it the ideal solution for applications where accuracy, resolution and fast settling of the outputs are required. In addition, the small form factor of the AD9778ABSVZ makes it suitable for a wide range of applications and implementations.
