DAC7612U

Digital To Analog Converters Overview

The DAC7612U is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates on a single +5V power supply with a voltage range of 4.75V to 5.25V and consumes 3.5mW of power. The device features a serial input interface compatible with standard DSPs and microcontrollers, utilizing CLK, SDI, CS, and LOADDACS signals. It includes an internal 2.435V reference and high-speed rail-to-rail output amplifiers. Each channel achieves full-scale settling within 7µs. The component is housed in an 8-lead SOIC package and is specified for industrial operating temperatures ranging from -40°C to +85°C.

• Battery-powered devices requiring low power consumption

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the procurement documentation matches the required industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status as defined in the latest official release notes before finalizing purchase orders.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with 12-bit resolution and low power consumption is required. The 7µs settling time and 130 ksps sampling rate suit moderate-speed applications. Verify that the system logic levels are compatible with the 3-wire serial interface requirements and that the single +5V supply constraint fits the board design.

Digital To Analog Converters Part Context

The DAC7612U belongs to the DAC7612 family of dual 12-bit serial DACs. It shares functional similarities with the DAC7611 but provides two channels instead of one. The U suffix indicates the surface-mount SOIC-8 package variant. This part serves as a cost-effective alternative to parallel DACs in space-constrained designs requiring moderate accuracy.

Digital To Analog Converters Replacement Considerations

The DAC7612UB is a verified equivalent variant within the same series. Check for pin-compatible alternatives such as the DAC7611 if only a single channel is needed. Verify that any substitute maintains the same 12-bit resolution and serial interface protocol.
