AD7533KR

AD7533KR is Analog Devices’ 12-bit multiplying digital-to-analog converter (MDAC). It converts a 12-bit digital input into an analog output that is proportional to an external reference (i.e., the output is the product of the digital word and the reference). This allows digitally programmable analogue levels with a wide dynamic range; the device can be wired for current or voltage output depending on the external circuit.
Key points:
- 12-bit, monotonic accuracy with relatively fast settling and low glitch
- Multiplying DAC capability for flexible full-scale ranges
- Typically supports single-supply operation and external reference inputs
- Packaging/specifics denoted by the KR suffix (package type/temperature grade varies by lot)
Applications include precision gain control, waveform generation, calibration, and instrumentation. For exact electrical specs, pinout, and packaging (including what KR means for your lot), consult the latest AD7533 data sheet or Analog Devices product page.

AD7533KR features (concise):
- 12-bit multiplying DAC (output scaled by external reference)
- Parallel data input (12‑bit) with update strobe
- Current-output DAC (requires external op-amp to convert to voltage)
- Wide analog supply range and suitable for bipolar/unipolar operation with reference
- Monotonic with good integral and differential linearity
- Fast settling with low glitch energy
- Industrial temperature range (and suitable for rugged environments)
- Packaging: KR variant (standard DIP/through‑hole style as per datasheet)
Note: For exact specs (settling time, INL/DNL, reference ranges, and precise package), please consult the AD7533KR datasheet.

- Pin count: 16 pins
- Function: Triple 8-bit multiplying digital-to-analog converter (three independent DAC channels) with current outputs (Iout1–Iout3) and a common reference; data is loaded via an 8-bit parallel data input and the outputs typically require external conversion to voltage with op-amps.

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits; publicly traded on NASDAQ (ticker: ADI).
