DAC312HS-REEL

Digital To Analog Converters Overview

The DAC312HS-REEL is a 12-bit high-speed multiplying digital-to-analog converter manufactured by Analog Devices Inc. It features a 20-pin Small Outline Lead (SOL) package and operates within an industrial temperature range of -40°C to +85°C. The device provides differential current outputs with a typical settling time of 250 ns and guaranteed monotonicity. It interfaces directly with TTL, CMOS, ECL, and PMOS/NMOS logic families via an adjustable logic threshold. Power consumption is typically 225 mW at ±15 V supplies, supporting a wide supply voltage range from +4.5 V to +18 V and -10.8 V to -18 V.

• Programmable test equipment

Digital To Analog Converters Procurement Notes

Verify the specific grade suffix (H) corresponds to the required industrial temperature range (-40°C to +85°C). Confirm the REEL packaging designation matches automated assembly requirements. Ensure the SOL-20 footprint aligns with the PCB design, as pinout compatibility with legacy AM6012 devices should be validated against the datasheet outline dimensions.

Digital To Analog Converters Selection Notes

Select the DAC312HS variant for industrial temperature applications requiring -40°C to +85°C operation. The HS suffix indicates the 20-pin SOL plastic package. For commercial temperature ranges (0°C to +70°C), consider the DAC312HE or DAC312HR variants. Ensure the reference current (IREF) is maintained between 100 µA and 1.0 mA for optimal monotonic performance in multiplying applications.

Digital To Analog Converters Part Context

The DAC312 series utilizes a hybrid architecture combining a 9-bit master D/A converter with a 3-bit segment generator. This design ensures uniform step sizes and guarantees monotonicity without the stringent matching requirements of a standard 12-bit R-2R ladder. The device offers industry-standard AM6012 pinout compatibility and is available in hermetic DIP, plastic DIP, and SOL packages.
