AD7945BRS Description

Short technical summary and product information.

The AD7945BRS is a high-speed, 12-bit multiplying digital-to-analog converter (DAC) manufactured by AD. It operates from a single +5 V supply in Normal Mode and a single +3.3 V to +5 V supply in Biased Mode. This DAC features guaranteed specifications with +3.3 V/+5 V supply, including 0.5 LSBs Integral Non-Linearity (INL) and Differential Non-Linearity (DNL).

Key electrical characteristics include a low power consumption of 5 mW typical, a fast interface with a 40 ns write pulsewidth, low glitch energy of 60 nV-s, and fast settling time of 600 ns to 0.01% with an AD843 amplifier. The device also offers a relative accuracy of ±0.5 LSBs and a gain error of ±2 LSBs.

The AD7945BRS is designed for applications such as battery-powered instrumentation and laptop computers. It serves as an upgrade for older 754x series DACs in 5 V designs. The device is available in a 20-lead SSOP package, suitable for surface mount applications.

This multiplying DAC provides a 12-bit resolution and is designed to replace industry-standard DACs, offering superior speed and power consumption performance.
