Descripción general

Description

REF02BU/2K5 is a fixed 2.5 V precision voltage reference from the REF02 family, usually in a BU (TO-92) package. It provides a stable 2.5 V reference ideal for ADC/DAC references, instrumentation, and calibration.
Key points:
- Output: fixed 2.5 V.
- Supply: operates from a broad Vin range (typical ≈ 4–30 V).
- Output current: can source/sink a few mA; minimum load current is required to maintain regulation.
- Performance: low output impedance with good line/load regulation and temperature stability (ppm/°C range depending on grade).
- Packaging: BU denotes the TO-92 style version; 2K5 denotes 2.5 V nominal output.
- Usage: connect Vin to a suitable supply, GND to ground, Vout to the reference node; add bypass capacitors close to the device for noise reduction.
Applications: ADC/DAC references, precision measurement, instrumentation, sensor calibration. For exact electrical specs (tolerances, tempco, min load, max current), consult the latest REF02BU/2K5 datasheet.

Package

REF02BU/2K5 is the REF02 in an 8‑pin plastic DIP package (DIP‑8).

Pinout

REF02BU/2K5 is a 3‑terminal fixed voltage reference (2.5 V).
- Pin count: 3
- Pin functions: one pin is the 2.5 V reference output (Vout), one pin is the supply input (Vin), and one pin is the ground/return (GND).
Note: exact pin order depends on the package (BU TO‑92 style). Check the datasheet for the precise pinout.

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

REF02BU/2K5 is a 2.5-V, low-drift precision voltage reference. Common applications:
- Reference source for precision DACs/ADCs in data acquisition and instrumentation
- Calibration reference for voltmeters, multimeters, and test equipment
- Stable reference for precision op-amps, comparators, and instrumentation amplifiers
- Reference for low-drift analog circuits and regulators
- Portable/battery-powered instrumentation requiring a stable 2.5-V rail

Equivalent

Equivalents (2.5 V reference):
- ADR02/ADR02A (Analog Devices)
- LM336-2.5 (National Semiconductor)
- LM385-2.5 (National)
- TL431 (2.495 V shunt regulator; use with a resistor network to approximate 2.5 V)
Notes: direct pin-compatible substitutes vary by package; check accuracy, tempco, bias current, and pinout. Some 2.495 V references may be used where exact 2.5 V isn’t critical.
