DAC7741YC/2K

Digital To Analog Converters Overview

The DAC7741YC/2K 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 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 includes double-buffered data input, input register read-back, and user-programmable reset to min-scale (0000H) or mid-scale (8000H). Powered by dual analog supplies (+/-11.4V to +/-15.75V) and a +5V logic supply, it consumes 150mW maximum power in a LQFP-48 package.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix /2K indicates tape and reel packaging containing 2000 units. Confirm the 'YC' grade designation corresponds to the specified linearity and differential nonlinearity parameters for the –40°C to +85°C operating range. Ensure compatibility with the required LQFP-48 footprint and verify that the component meets RoHS3 compliance standards before integration.

Digital To Analog Converters Selection Notes

Select the DAC7741YC/2K when full 16-bit monotonicity is required across the extended industrial temperature range. This grade offers tighter linearity specifications compared to lower grades. Ensure the application can accommodate the necessary dual analog power supplies and +5V logic supply. Verify that the parallel interface timing requirements align with the system controller capabilities.

Digital To Analog Converters Part Context

The DAC7741 is a high-performance 16-bit DAC designed for precision applications. The DAC7741YC variant specifically targets environments requiring operation from –40°C to +85°C with enhanced linearity accuracy. The /2K suffix denotes the standard tape and reel packaging format intended for automated surface-mount assembly processes.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other DAC7741 grades such as DAC7741YB/2K or DAC7741YL/2K, noting differences in linearity error specifications and operating temperature ranges. Cross-grade replacements require verification of monotonicity and offset/gain drift characteristics against the original design requirements.
