DAC7741Y/250

Digital To Analog Converters Overview

The DAC7741Y/250 is a 16-bit single-channel digital-to-analog converter featuring an internal +10V reference and parallel interface. It provides monotonic performance over the –40°C to +85°C temperature range with a typical settling time of 5 µs to ±0.003% FSR for a 20V step. The device supports configurable unipolar (0V to +10V) or bipolar (±5V, ±10V) output ranges via pin strapping. It consumes 100mW typically with the internal reference enabled and includes double-buffered data inputs for asynchronous updates.

Digital To Analog Converters Feature Summary

• Integrates a low-drift +10V internal voltage reference
• Supports user-configurable unipolar and bipolar output voltage ranges
• Features double-buffered input registers for asynchronous analog updates
• Includes programmable reset control for min-scale or mid-scale initialization

Digital To Analog Converters Applications

• Automatic test equipment
• 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 /250 corresponds to the tape and reel packaging quantity of 250 units as documented in the manufacturer's package ordering information. Confirm that the Y grade meets the required linearity specifications for the intended application environment. Ensure compatibility with the LQFP-48 package footprint during PCB layout design.

Digital To Analog Converters Selection Notes

Select this component when a 16-bit resolution with guaranteed monotonicity across the industrial temperature range is required. Consider the internal reference capability if external precision references are undesirable. Evaluate the power supply requirements, noting the need for dual analog supplies for bipolar operation versus a negative rail for unipolar modes.

Digital To Analog Converters Part Context

This part belongs to the DAC7741 family of high-performance digital-to-analog converters. The Y designation indicates a specific performance grade regarding linearity error within the LQFP-48 package. Other grades such as YB, YC, and YL offer tighter linearity specifications but may differ in operating temperature ranges or pricing structures.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other DAC7741 grades such as DAC7741YB/250, DAC7741YC/250, and DAC7741YL/250, which share the same package and pinout but offer improved linearity metrics.
