DAC7512E/250G4

Digital To Analog Converters Overview

The DAC7512E/250G4 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 electrical specifications include a sampling rate of 95 kS/s, a settling time of 12 µs, and a maximum INL of ±8 LSB. The component functions within an operating temperature range of -40°C to +105°C and is housed in an 8-VSSOP package.

Digital To Analog Converters Procurement Notes

Verify the G4 suffix indicates lead-free composition and compliance with RoHS standards as per manufacturer documentation. Confirm the specific tape-and-reel quantity associated with the /250 designation matches project requirements. Ensure ESD handling procedures are followed during assembly due to the sensitivity of CMOS input structures.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit resolution is sufficient for the application. Consider the 8-VSSOP package constraints regarding thermal dissipation and PCB space. Verify that the required serial clock speed does not exceed the maximum limits defined in the electrical characteristics table for reliable data transfer.

Digital To Analog Converters Part Context

This part belongs to the DAC7512 family of low-power, 12-bit digital-to-analog converters. The 'E' designation specifies the 8-VSSOP package variant, while the '/250' indicates reel packaging. The 'G4' suffix denotes environmental compliance attributes. It serves as a direct replacement for earlier non-compliant versions within the same functional series.
