The AD7945BR from Analog Devices is a high-speed, 12-bit multiplying digital-to-analog converter (DAC). It is designed to operate 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 supplies, including ±0.5 LSBs of Integral Nonlinearity (INL) and Differential Nonlinearity (DNL).
Key performance characteristics include low power consumption, typically 5 mW, and a fast interface with a 40 ns write pulsewidth. It also boasts low glitch energy of 60 nV-s and a fast settling time of 600 ns to 0.01% when used with an AD843 amplifier. The AD7945BR is suitable for applications such as battery-powered instrumentation and laptop computers, offering an upgrade path for older 754x series DACs.
This component is part of the AD7943/AD7945/AD7948 family, which includes serial and parallel interface options. The AD7945 specifically features a 12-bit parallel interface. It is designed to replace industry-standard DACs while providing superior speed and power efficiency.
