DAC7612UB

Digital To Analog Converters Overview

The DAC7612UB is a dual-channel, 12-bit serial input digital-to-analog converter manufactured by Texas Instruments. It operates on a single +5V supply and guarantees monotonicity over the industrial temperature range of -40°C to +85°C. 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 power consumption of 3.5 mW. Differential nonlinearity (DNL) and integral nonlinearity (INL) are specified at ±0.25 LSB. It utilizes a synchronous 3-wire serial interface compatible with DSPs and microcontrollers.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'UB' against the manufacturer's current datasheet to confirm package type and temperature grade specifications. Ensure compatibility with the required serial communication protocol before integration. Check for moisture sensitivity levels if the component has been stored for extended periods. Confirm RoHS compliance status based on the latest manufacturing documentation provided by Texas Instruments.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with integrated references and amplifiers is required to reduce board space. The 12-bit resolution and ±0.25 LSB linearity errors suit applications demanding moderate precision. Verify that the 130 kS/s update rate meets the system bandwidth requirements. Consider the SOIC-8 package constraints for thermal management and PCB layout availability.

Digital To Analog Converters Part Context

The DAC7612UB belongs to the DAC7612 family of dual 12-bit DACs from Texas Instruments. This series is designed for general-purpose analog output applications where size and power efficiency are critical. The device replaces older discrete solutions by integrating the reference and buffer stages directly onto the silicon die.

Digital To Analog Converters Replacement Considerations

Check for direct pin-compatible alternatives within the TI DAC portfolio that may offer updated packaging or enhanced linearity specifications. Verify functional equivalence regarding the serial interface timing and internal reference voltage accuracy when substituting with other dual-channel DAC models.
