DAC7741YL/2K

Digital To Analog Converters Overview

The DAC7741YL/2K is a 16-bit single-channel digital-to-analog converter featuring an internal +10V reference and a parallel interface. It provides 16-bit monotonicity over the specified operating temperature range with configurable voltage output swings of ±10V, ±5V, or +10V via pin strapping. The device includes a high-speed output amplifier with a maximum settling time of 5 µs to ±0.003% FSR for a 20V full-scale change. It operates from dual analog supplies (VCC: +11.4V to +15.75V; VSS: -15.75V to -4.75V) and a +5V digital supply (VDD: +4.75V to +5.25V). The part is housed in a LQFP-48 package and supports user-programmable reset controls.

Digital To Analog Converters Feature Summary

• Double-buffered data input architecture enabling asynchronous updates of the analog output and data read-back for integrity verification.
• User-programmable reset control allowing the DAC output to reset to min-scale (0000H) or mid-scale (8000H), overriding register values.
• Configurable unipolar or bipolar operation through external pin strapping for flexible voltage range selection.

Digital To Analog Converters Applications

• Automatic test equipment
• Industrial process control
• Closed-loop servo control
• Motor control
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix /2K indicates tape and reel packaging containing 2000 units. Confirm the 'YL' grade corresponds to the 0°C to +70°C operating temperature range. Ensure compatibility with the required LQFP-48 footprint and verify that the internal reference configuration meets system power budget requirements.

Digital To Analog Converters Selection Notes

Select this component when 16-bit resolution and guaranteed monotonicity are required across the industrial temperature range. The integrated +10V reference simplifies design by reducing external component count. Consider the double buffering feature if synchronized multi-DAC updates or data verification prior to conversion are necessary for the application.

Digital To Analog Converters Part Context

The DAC7741 belongs to Texas Instruments' Burr-Brown legacy portfolio of precision data converters. This series is designed for applications requiring high accuracy and low power consumption. The DAC7741 specifically targets environments where reliable analog signal generation is critical, such as instrumentation and automated manufacturing systems.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other parts within the DAC7741 family such as DAC7741YB/2K or DAC7741YC/2K, which offer different linearity grades but share the same package and interface. Verify that any replacement maintains the required monotonicity and operating temperature specifications.
