DAC7513N/3K

DAC7513N/3K is a family of 8-bit multiplying digital-to-analog converters with a serial (SPI-like) input. It converts an 8-bit digital word into an output current that is proportional to the applied reference, so full-scale output is set by the external reference and an I/V stage yields the usable voltage. As a multiplying DAC, the output range follows the reference, which is useful for gain control, calibration, and waveform generation. The N and 3K suffixes indicate packaging and temperature-grade variants; check the datasheet for exact differences.
Key points:
- 8-bit, monotonic conversion
- Serial interface: CS, SCLK, SDI (SPI-like)
- Output is a current (Iout) that requires an external I/V amplifier to produce voltage
- Needs an external reference and typical power-supply rails
Applications: instrumentation, calibration, digital control loops, test equipment, and signal generation.
For precise specs (FS current, reference requirements, timing, pinout), consult the specific DAC7513N/3K datasheet.

Equivalents depend on exact specs. DAC7513N/3K is a 12‑bit multiplying DAC (likely SPI) in an N/3K package. To give precise cross‑refs, please share: supply voltage, reference range, output type (voltage/current), interface, package, and temperature range. With that, I can list exact substitutes from TI, Analog Devices, Microchip, and Maxim that match.

- Pin count: 8 pins (N/3K package, e.g., DIP-8/SOIC-8)
- Function: 12-bit multiplying digital-to-analog converter (Iout current output); output current is proportional to the input code and reference, typically converted to voltage with an external op-amp.

- Manufacturer: National Semiconductor (the DAC7513N/3K was produced by National Semiconductor; the company is now part of Texas Instruments).
- What kind of company: an American semiconductor company that designs and manufactures integrated circuits (ICs) and other electronic semiconductors.

Typical applications for DAC7513N/3K:
- Industrial automation and process control (programmable analog setpoints and drive signals)
- Data acquisition and instrumentation (sensor excitation, reference signals, gain/offset adjustment)
- Test, measurement, and calibration equipment (signal generation, calibration sources)
- Automatic test equipment and lab instruments
- Embedded systems requiring precise, low-noise programmable analog outputs for control loops and waveform generation

The DAC7513N/3K comes in an 8-pin plastic DIP package (DIP-8), N suffix.
