DAC7512N/250

Digital To Analog Converters Overview

The DAC7512N/250 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 operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device supports serial interfaces including SPI, DSP, Microwire, and QSPI. Key electrical parameters include a settling time of 12 µs, a maximum sampling rate of 95 kS/s, and a typical operating current of 135 µA. It is housed in an 8-pin SOT-23 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 Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure that any ordering suffixes do not alter the functional characteristics or pinout configuration unless explicitly stated in the manufacturer's datasheet. Cross-reference the component marking with the official part identification guide to prevent substitution errors during assembly.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit resolution is required with minimal power consumption. The rail-to-rail output eliminates the need for external level shifting in low-voltage systems. Verify that the system clock speed does not exceed the 95 kS/s limit and that the serial interface timing aligns with the selected communication protocol mode.

Digital To Analog Converters Part Context

This device belongs to the DAC7512 family of low-power digital-to-analog converters. It shares architectural similarities with the DAC7513 but differs in pin configuration and specific interface optimizations. The N suffix indicates the SOT-23-8 package variant, distinguishing it from the E suffix VSSOP version. It serves as a direct replacement for older Burr-Brown series components in legacy designs.

Digital To Analog Converters Replacement Considerations

The DAC7512E/250 offers identical electrical performance in an 8-VSSOP package. The DAC7513N/250 provides similar functionality but requires verification of pin compatibility due to potential interface differences.
