DAC7612U/2K5

Digital To Analog Converters Overview

The DAC7612U/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 internal 2.435V reference, shift register, latch, and rail-to-rail output amplifiers. Key electrical parameters include a sampling rate of 130 ksps, a typical settling time of 7 µs to 1 LSB for full-scale steps, and a 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
• Synchronous serial interface supporting standard communication protocols
• Internal reference voltage source eliminates external component requirements
• Rail-to-rail output capability for maximum dynamic range

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation
• Battery-powered instrumentation due to low power consumption
• Programmable gain amplifier biasing circuits
• Portable data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration. The /2K5 designation indicates tape and reel packaging, distinct from tube variants. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Ensure the selected variant matches the required quantity handling method for the production line.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with integrated buffering is required without external reference components. The 12-bit resolution and 130 ksps speed suit moderate-speed applications. Consider the SOIC-8 package constraints for PCB layout. Verify that the single 5V supply aligns with the system power architecture.

Digital To Analog Converters Part Context

This part belongs to the DAC7612 family of dual 12-bit serial DACs. It shares core functionality with the DAC7612U but differs in packaging format. The family is designed for cost-sensitive industrial applications where space and power efficiency are critical constraints.
