DAC7741YC/2KG4

Digital To Analog Converters Overview

The DAC7741YC/2KG4 is a 16-bit single-channel digital-to-analog converter featuring an internal +10V reference and parallel interface. It provides 16-bit monotonicity over the –40°C to +85°C temperature range with a settling time of 5 µs to ±0.003% FSR for a 20V step. The device supports configurable voltage outputs of ±10V, ±5V, or +10V via pin strapping. It operates from dual analog supplies (VCC/VSS) ranging from ±11.4V to ±15.75V and a +5V logic supply (VDD). Power consumption is typically 100mW with the internal reference enabled.

Digital To Analog Converters Feature Summary

• Integrated +10V low-drift internal reference with adjustable output
• Double-buffered data input allowing asynchronous updates and read-back
• Configurable unipolar or bipolar operation through external resistor network
• User-programmable reset control for min-scale or mid-scale initialization

Digital To Analog Converters Applications

• Automatic test equipment (ATE)
• Industrial process control systems
• Closed-loop servo control
• Motor control applications
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm transport media and quantity specifications. Ensure the component grade matches the required operating temperature range for the intended application environment.

Digital To Analog Converters Selection Notes

Select this model for high-precision applications requiring full 16-bit monotonicity across wide temperature variations. Consider the LQFP-48 package dimensions for PCB layout constraints. Verify that the system power supplies can accommodate the specified VCC and VSS ranges for the desired output configuration.

Digital To Analog Converters Part Context

This component belongs to the DAC7741 family of 16-bit voltage-output DACs. Other grades in the series include DAC7741Y, DAC7741YB, and DAC7741YL, which offer varying linearity specifications and operating temperature ranges. The DAC7741YC represents a higher precision grade suitable for demanding industrial environments.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include DAC7741Y, DAC7741YB, and DAC7741YL. Verify that the replacement part's linearity error (INL/DNL) and operating temperature range meet the design requirements before implementation.

Digital To Analog Converters FAQ

How is the internal reference enabled?

The internal reference is enabled by pulling the REFEN pin LOW. When enabled, the REFOUT pin provides the buffered +10V reference.

What is the function of the RSTSEL pin?

The RSTSEL pin determines the target state during a reset. A HIGH level resets the DAC register to mid-scale (8000H), while a LOW level resets it to min-scale (0000H).

Can the DAC7741 operate with an external reference?

Yes, by disabling the internal reference (REFEN HIGH) and applying an external voltage between 4.75V and VCC–1.4V to the REFIN pin.
