DAC312FR

Digital To Analog Converters Overview

The DAC312FR is a 12-bit multiplying digital-to-analog converter manufactured by Analog Devices Inc. It features a 9-bit master D/A converter combined with a 3-bit segment generator to ensure monotonicity and low differential nonlinearity of ±1 LSB. The device provides high-speed performance with a typical settling time of 250 ns and operates over an industrial temperature range of –40 °C to +85 °C. It utilizes a 20-pin hermetic ceramic dual in-line package (Cerdip-20, Q-20 suffix). Key electrical characteristics include a full-scale current of approximately 4 mA at a 10 V reference, a power supply range of +4.5 V to +18 V and –18 V to –10.8 V, and a typical power dissipation of 225 mW.

Digital To Analog Converters Procurement Notes

Verify the specific grade suffix 'F' corresponds to the industrial temperature range of –40 °C to +85 °C and the ±1 LSB DNL specification. Confirm the package option 'R' indicates the 20-pin hermetic Cerdip format. Ensure compatibility with existing board layouts requiring the industry-standard AM6012 pinout configuration.

Digital To Analog Converters Selection Notes

Select the DAC312FR for applications requiring precise multiplying functionality with fast settling times. The device supports reference currents up to 1.0 mA and offers wide logic input swing capabilities. Consider the thermal resistance of the hermetic package when designing for maximum power dissipation limits under varying ambient conditions.

Digital To Analog Converters Part Context

The DAC312 series includes variants such as the DAC312E (commercial, 0 °C to +70 °C) and DAC312H (industrial, plastic DIP/SOL). The DAC312FR specifically denotes the industrial temperature grade housed in a hermetic ceramic package. This variant is part of a family designed for high-reliability applications where environmental stability and direct logic interfacing are critical requirements.
