DAC10GS

Digital To Analog Converters Overview

The DAC10GS is a 10-bit multiplying digital-to-analog converter manufactured by Analog Devices Inc. in an 18-lead SOIC package. It features a current-steering architecture with parallel binary or offset binary inputs. Key electrical specifications include a typical settling time of 85 ns to 0.05% of full scale, a maximum nonlinearity of 1 LSB, and a propagation delay of 50 ns. The device operates on dual supplies ranging from ±10 V to ±18 V, consuming up to 285 mW at ±15 V. It provides true and complementary analog current outputs with wide voltage compliance.

Digital To Analog Converters Feature Summary

• 10-bit resolution with monotonic operation over the specified temperature range
• Fast settling time of 85 ns (typical) to 0.05% of full scale
• Multiplying capability with linear relationship between reference current and output
• Wide logic input swing allowing direct interface with TTL, CMOS, and ECL families

Digital To Analog Converters Applications

• High-speed data acquisition systems requiring fast settling times
• Pulsed reference applications utilizing internal clamp for quick recovery
• CRT deflection and cable driving using quasi-differential output configurations
• Balanced load applications such as center-tapped coils and transformers

Digital To Analog Converters Procurement Notes

Verify the specific suffix GS indicates the 18-lead SOIC plastic package variant. Confirm that the operating temperature range meets the requirement of 0°C to +70°C. Ensure the design accounts for the ESD sensitivity of the device during handling and assembly processes.

Digital To Analog Converters Selection Notes

Select this component when a 10-bit resolution with sub-100 ns settling speed is required. Consider the parallel interface constraint if high pin count is acceptable. Evaluate power dissipation requirements, as the device draws significant current from the negative supply rail compared to modern low-power alternatives.

Digital To Analog Converters Part Context

The DAC10 series includes variants with different packages: DAC10FX and DAC10GX use hermetic Cerdip Q-18 packages, while DAC10GP uses a Plastic DIP N-18 package. The DAC10GS specifically denotes the Wide Body SOIC R-18 configuration. All variants share identical electrical characteristics and pinouts.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pin compatibility and electrical parameter matching if considering alternative manufacturers' 10-bit current-steering DACs.

Digital To Analog Converters FAQ

What is the maximum nonlinearity specification for the DAC10GS?

The maximum integral nonlinearity (NL) is 1 LSB, and the maximum differential nonlinearity (DNL) is 0.7 LSB.

How does the DAC10GS handle unused output pins?

Unused output pins must be connected to ground or a point capable of sourcing the full-scale current. Leaving an output pin open is prohibited.

What is the recommended compensation capacitor value for fixed reference operation?

A 0.01 μF capacitor is recommended between Pin 18 (COMP) and V– for fixed reference operation.
