DAC312HP

Digital To Analog Converters Overview

The DAC312HP is a 12-bit high-speed multiplying digital-to-analog converter manufactured by Analog Devices Inc. It features a 250 ns settling time and ±1 LSB differential nonlinearity over the industrial temperature range of –40 °C to +85 °C. The device provides differential current outputs with a compliance range of –5 V to +10 V and operates on power supplies from +4.5 V to +18 V and –18 V to –10.8 V. Packaged in a 20-lead plastic DIP, it interfaces directly with TTL, CMOS, ECL, and PMOS/NMOS logic families via an adjustable threshold pin.

Digital To Analog Converters Feature Summary

• 12-bit resolution with guaranteed monotonicity
• Fast 250 ns settling time to within ±1/2 LSB
• Differential current outputs (0 to 4 mA) with wide voltage compliance
• Direct interface capability for TTL, CMOS, ECL, and PMOS/NMOS logic

Digital To Analog Converters Applications

• A/D converters
• Data acquisition systems
• Video display drivers
• Programmable test equipment

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'HP' corresponds to the Plastic DIP-20 package and the –40 °C to +85 °C temperature grade as defined in the manufacturer's ordering guide. Confirm that the required performance specifications align with the DAC312H electrical characteristics table provided in the datasheet.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution and 250 ns settling speed are required for multiplying applications. Ensure the system design accommodates the specified dual power supply rails (+4.5 V to +18 V and –18 V to –10.8 V). Verify that the logic family used in the circuit can interface correctly with the DAC312's input threshold requirements.

Digital To Analog Converters Part Context

The DAC312HP belongs to the DAC312 series of monolithic multiplying D/A converters. This series utilizes a hybrid architecture combining a 9-bit master D/A converter with a 3-bit segment generator to achieve accurate 12-bit performance. The HP variant specifically denotes the plastic DIP packaging option within the broader product line that also includes hermetic cerdip and SOL packages.

Digital To Analog Converters Replacement Considerations

The DAC312HS is a direct functional substitute offering identical electrical specifications but housed in a 20-pin SOL package instead of the plastic DIP.
