DAC7615E/1K

Digital To Analog Converters Overview

The DAC7615E/1K is a quad, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R architecture with buffered voltage outputs and serial SPI interface compatibility. The device operates on a single 5V digital supply and dual ±5V analog supplies within a 4.75V to 5.25V range. Key electrical specifications include a settling time of 10µs, a sampling rate of 89 kS/s, and power consumption of 15 mW. Nonlinearity errors are specified at ±2 LSB for INL and ±1 LSB for DNL, with a gain error of 0.2% FSR. It functions in temperatures from -40°C to +85°C and is housed in a 20-SSOP package.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels with buffered voltage outputs for direct drive capability.
• Supports standard serial communication protocols including SPI, Microwire, and QSPI via a simple three-wire interface.
• Features internal reset functionality to mid-scale output levels upon power-up or command activation.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable power supply architectures
• Data acquisition systems with analog output capabilities

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix '/1K' confirms the reel packaging quantity of 1000 units as documented by the manufacturer. Ensure the component meets RoHS3 compliance standards required for the target assembly process. Confirm that the 20-SSOP footprint matches the design board layout constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel solution is required instead of discrete single-channel converters to save board space. The 12-bit resolution and 10µs settling time suit moderate-speed applications. Verify that the ±5V analog supply requirement aligns with the system power budget, as it differs from single-supply alternatives.

Digital To Analog Converters Part Context

This part belongs to the DAC7615 family of precision digital-to-analog converters. It shares architectural similarities with the DAC7614 but offers distinct pinout or feature variations defined by the datasheet. The '/1K' designation specifically indicates tape-and-reel packaging for automated surface-mount assembly processes.

Digital To Analog Converters Replacement Considerations

The DAC7615E/1KG4 is listed as an equivalent part number alias. Verify pin compatibility and electrical parameter equivalence against the official datasheet before substituting. Other family members like DAC7614 may require schematic adjustments due to functional differences.
