DAC7512N/3K

The DAC7512N/3K is the 3,000-piece reel code for the Texas Instruments DAC7512, a 12-bit rail-to-rail voltage-output DAC in a SOT-23-6 package. It runs from a single 2.7 V to 5.5 V supply, uses the supply as its reference and accepts a three-wire SPI-compatible serial interface clocked up to 30 MHz, with power-on reset to zero scale. A buffered rail-to-rail output in six pins removes the op amp and reference a discrete design would need, which keeps precision setpoint, trim and calibration channels cheap and small in industrial controls, portable instruments and process transmitters. Selection advice: the /3K suffix is only the large-reel packing of the same die, and the part suits new designs as well as sustainment of the long-running DAC7512 footprint; if an internal reference or 16-bit resolution is required, step to a different family rather than reworking this pinout.
