Description

AD580UH/883B is a fixed-output precision voltage reference from Analog Devices (the AD580 family). It is designed to provide a very stable reference voltage for analog circuits, especially ADCs, DACs, and instrumentation front ends. The “UH” suffix denotes a specific grade/package, and “883B” is the lot/date code for that part.
Key points:
- Purpose: stable reference voltage with low drift and low noise.
- Applications: biasing ADCs/DACs, precision instrumentation, calibration.
- Characteristics (variant dependent): low temperature coefficient, low output noise, good load and long-term stability, and adequate output current.
- Use notes: provide proper decoupling near the device, observe the recommended bias/load conditions, and operate within the datasheet’s supply range.
- For exact voltage, tolerance, tempco, pinout, and package details, refer to the specific AD580UH datasheet for your lot and variant.

Equivalent

AD580UH/883B is a 1.235 V precision shunt voltage reference (TO-92). Direct equivalents include:
- LM336-1.235 family (e.g., LM336-1.235, LM336A-1.235, LM336Z-1.235)
- LM4040-1.235 (precision shunt reference)
Note: pinout and tempco vary by part; verify datasheets and package compatibility before substituting.

Features

I don’t have the exact AD580UH/883B datasheet memorized. Typical features for the AD580 voltage-ref family include:
- Fixed reference voltage (specific Vout per variant; check datasheet for AD580UH)
- Very low temperature coefficient and excellent long-term stability
- Low output noise and good dynamic performance
- Low output impedance with tight line and load regulation
- Wide supply range and single-supply operation
- Robustness features (e.g., short-circuit protection) and reliability-grade option (UH)
- Available in common IC packages (e.g., DIP8/SO8) with industrial/military-grade variants
For precise numbers (Vout, initial accuracy, tempco, noise, load current, regulations) please consult the official AD580UH/883B datasheet.

Pinout

- Pin count: 8 pins (DIP-8 / equivalent package)
- Function: Precision voltage reference IC used to provide a stable reference voltage for analog circuits (e.g., ADC/DAC reference).

Manufacturer

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 for various markets.

Package

8-pin DIP (DIL) package. The UH suffix denotes the DIP-8 form factor used by Analog Devices for the AD580; other package options may exist, but this variant is DIP-8.
