DAC312HSZ

Digital To Analog Converters Overview

The DAC312HSZ is a 12-bit high-speed multiplying digital-to-analog converter manufactured by Analog Devices Inc. It features a parallel interface and delivers differential current outputs with a typical settling time of 250 ns to ±1/2 LSB. The device operates on dual power supplies ranging from +4.5 V to +18 V and -10.8 V to -18 V, consuming approximately 225 mW at lower supply voltages. Key electrical specifications include a differential nonlinearity (DNL) of ±1 LSB and an integral nonlinearity (INL) of ±0.05% FSR. It is housed in a 20-pin Small Outline Package (SOL).

Digital To Analog Converters Feature Summary

• 12-bit resolution with guaranteed monotonicity over the full operating temperature range.

• High output voltage compliance range from –5 V to +10 V.
• Direct logic interface capability for TTL, CMOS, ECL, and PMOS/NMOS families via adjustable threshold pin.

Digital To Analog Converters Applications

• A/D converters requiring precise input stages.
• Data acquisition systems needing fast conversion rates.
• Video display drivers for CRT deflection or signal generation.
• Programmable test equipment utilizing multiplying capabilities.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'HSZ' corresponds to the 20-pin SOL package and industrial temperature grade (-40°C to +85°C). Confirm that the ordering code matches the manufacturer's current datasheet revision, as suffixes may indicate variations in packaging or material composition without altering functional performance. Cross-reference with official distributor catalogs for availability status.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, high-speed 12-bit DAC with differential current outputs is required. Ensure the application supports parallel data input and provides the necessary dual power supply rails (+4.5V to +18V and -10.8V to -18V). Consider the 250 ns settling time and ±1 LSB DNL against system accuracy requirements. Verify thermal dissipation limits, as power consumption reaches up to 375 mW at maximum supply voltages.

Digital To Analog Converters Part Context

The DAC312HSZ belongs to the DAC312 series, which utilizes a hybrid architecture combining a 9-bit master D/A converter with a 3-bit segment generator. This design ensures uniform step size and monotonicity while maintaining low cost. The device is compatible with the industry-standard AM6012 pinout, facilitating drop-in replacements for legacy designs requiring similar performance characteristics.

Digital To Analog Converters Replacement Considerations

The DAC312HS is functionally equivalent but may differ in packaging or manufacturing lot details. For hermetic or plastic DIP variants, check the DAC312HP or DAC312FR models. Direct substitution requires verifying pin compatibility and ensuring the replacement part meets the same electrical specifications for linearity and settling time.
