AD7943BR Description

Short technical summary and product information.

The AD7943BR is a 12-bit multiplying digital-to-analog converter (DAC) from Analog Devices. It uses an R-2R architecture and provides a current-unbuffered output. The device accepts serial data input and operates from a single supply voltage range of 3.3V to 5V.

 

Key electrical specifications include integral nonlinearity (INL) and differential nonlinearity (DNL) of ±0.5 LSB maximum. The typical settling time is 600 ns to 0.01% when used with an AD843 amplifier. Power dissipation is typically 5 mW. The reference type is external.

 

The AD7943BR is available in a 16-SOIC package (0.295", 7.50mm width) with surface mount gull wing leads. It operates over a temperature range of -40°C to 85°C. The device is suitable for battery-powered instrumentation and laptop computers, and can serve as an upgrade for 754x series DACs in 5V designs.
