DAC7512N/3K

Digital To Analog Converters Overview

The DAC7512N/3K is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a resistor-string architecture with rail-to-rail output capability and voltage buffering. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. It supports serial interfaces including SPI, DSP, Microwire, and QSPI. Key performance metrics include a settling time of 12 µs, a sampling rate of 95 kS/s, and a typical operating current of 135 µA. Differential nonlinearity is specified at ±1 LSB, while integral nonlinearity is ±8 LSB. The component is housed in an SOT-23-6 package and functions within a temperature range of -40°C to +105°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm packaging configuration. The '/3K' suffix typically indicates a cut-tape or reel quantity of 3000 units, distinct from other packaging variants. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into surface-mount assembly processes.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit resolution is required with minimal power draw. Ensure the system interface supports the necessary serial protocol modes. Verify that the load impedance requirements are compatible with the internal buffer output capabilities. Consider the SOT-23-6 package constraints for thermal management and PCB layout space.

Digital To Analog Converters Part Context

This part belongs to the DAC7512 family of low-power, 12-bit digital-to-analog converters. It shares architectural similarities with the DAC7513 but differs in pinout and specific electrical characteristics. The N suffix denotes a plastic small-outline package variant. This series is designed for applications demanding high accuracy in compact form factors with limited power budgets.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitutes include the DAC7512E/250, which offers identical functionality in an 8-VSSOP package. The DAC7513N/250 serves as a functional alternative with similar specifications but may require pinout adaptation. Verify package dimensions and pin configurations before substituting.
