DAC7612UB/2K5

Digital To Analog Converters Overview

The DAC7612UB/2K5 is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates on a single +5V supply and features a serial input interface compatible with standard DSPs and microcontrollers. The device integrates an input shift register, latch, internal 2.435V reference, dual DACs, and high-speed rail-to-rail output amplifiers. Key electrical parameters include a sampling rate of 130 kS/s, a settling time of 7 µs to 1 LSB for full-scale steps, and a typical power consumption of 3.5 mW. It guarantees 12-bit monotonicity over the industrial temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with integrated buffered voltage outputs
• Serial interface supporting standard clock, data, chip select, and load signals
• Internal reference and rail-to-rail output amplifiers for simplified design

Digital To Analog Converters Applications

• Industrial process control systems requiring dual analog outputs
• Portable instrumentation powered by single 5V supplies
• Data acquisition systems interfacing with microcontrollers via serial buses

Digital To Analog Converters Procurement Notes

Verify the specific suffix '2K5' indicates reel packaging when sourcing components. Confirm the manufacturer part number matches Texas Instruments specifications exactly. Ensure compatibility with required operating temperatures and voltage levels before integration into final designs.

Digital To Analog Converters Selection Notes

Select this component for applications requiring two independent 12-bit voltage outputs with low power consumption. Verify that the serial interface timing meets system requirements. Consider the SOIC-8 package constraints for PCB layout and thermal management in enclosed environments.

Digital To Analog Converters Part Context

This part belongs to the DAC7612 family of dual 12-bit DACs. The 'UB' designation typically refers to the tube packaging variant, while '/2K5' specifies cut tape or reel packaging options. It shares core functionality with other members of the series but differs in shipping configuration and potentially minor mechanical attributes defined by the manufacturer.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative dual-channel 12-bit DACs from the same manufacturer only if they explicitly support identical pinouts and serial protocols.
