Description

AD584SH/883B is Analog Devices’ 12‑bit multiplying DAC (MDAC) with a current output. It converts a digital word into a current proportional to the product of the input code and an external reference voltage.
Key points
- The SH/883B suffix indicates device revision/package/lot for this part.
- Operation: apply Vref to Vref input; drive the 12‑bit input with TTL/CMOS data; Iout is the output current you convert to voltage with a resistor or op‑amp.
- Features: monotonic 12‑bit performance, full‑scale current set by Vref, suitable for single or dual supply, good temperature stability and fast settling.
- Applications: precision signal generation, DAC‑based control loops, waveform generation, and analog computation.
- Design notes: keep Vref clean, provide proper decoupling, and sense Iout with a high‑impedance load or an op‑amp for downstream circuitry or ADCs.

Equivalent

There isn’t an exact one‑to‑one cross for AD584SH/883B. To find substitutes, please provide: resolution (bits), output type (voltage/current), output range, supply rails, reference, temperature, and package. With those, I can suggest concrete equivalents from Analog Devices, TI/Burr‑Brown, and Intersil. You can also use vendor cross-reference tools for precise matches.

Features

AD584SH/883B features (concise):
- 12-bit multiplying DAC with current output (Iout)
- External reference input (IREF) sets full-scale current; Iout ≈ (Code/4095) × IREF
- Monotonic over the full code range and operating temperature
- Requires external op-amp to convert Iout to a voltage
- Wide supply range suitable for single or dual supplies
- SH/883B packaging (16-pin) for standard PCB integration
- Ideal for precision calibration, closed-loop control, and V→I conversion
- Designed for high accuracy with good temperature stability and low drift
Note: Exact electrical specs (e.g., IREF range, voltage ranges, temperature range) are in the datasheet; consult it for precise values.

Pinout

Pin count: 8 pins (SO-8/DIP-8).
Function: 12‑bit multiplying DAC with current output. Converts a digital input word into a proportional output current (Iout) that is set by a reference (Vref). Requires an external op-amp to convert Iout to a voltage; used for multiplying DAC applications with dual/single supplies as specified in the datasheet.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: A multinational American semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits.

Application

AD584SH/883B are multiplying DACs with current output. Typical applications:
- Programmable current sources and precision gain elements in instrumentation, process control, and servo/motor drives
- Analog signal generation for test equipment, calibration signals, and waveform synthesis
