DAC312HS

Digital To Analog Converters Overview

The DAC312HS is a 12-bit high-speed multiplying digital-to-analog converter manufactured by Analog Devices. It features a 20-pin SOL package and operates within a temperature range of -40°C to +85°C. The device provides differential current outputs with a typical settling time of 250 ns to ±1/2 LSB. Key electrical specifications include a differential nonlinearity (DNL) of ±1 LSB, integral nonlinearity (INL) of ±0.05% FSR, and a full-scale temperature coefficient of ±10 ppm/°C. It supports power supplies from +4.5 V to +18 V and -10.8 V to -18 V, consuming 225 mW at lower supply voltages.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'HS' corresponds to the 20-pin SOL plastic package and industrial temperature grade (-40°C to +85°C). Confirm that the DNL specification for this variant is ±1 LSB as listed in the ordering guide. Ensure compatibility with the required logic family interfaces and power supply ranges before integration.

Digital To Analog Converters Selection Notes

Select the DAC312HS when a 12-bit resolution with fast 250 ns settling time is required in a surface-mount SOL package. This model is suitable for applications needing direct logic interfacing without additional level shifters. Consider the ±1 LSB DNL specification if tighter linearity than the commercial grade is necessary for the target environment.

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 across the full operating temperature range. The DAC312HS represents the industrial temperature version of this technology housed in a standard industry pinout compatible with legacy AM6012 designs.

Digital To Analog Converters Replacement Considerations

The DAC312HS shares the industry-standard AM6012 pinout. Potential replacements include other 12-bit multiplying DACs with similar settling times and differential outputs, provided they match the 20-pin SOL footprint and voltage requirements.
