Detailed Description

AD8620BR is a dual, precision JFET‑input operational amplifier in an 8‑SOIC package. It offers very low input bias current, very low offset, fast slew rate, and a wide gain bandwidth, making it ideal for high‑impedance sensing, precision signal conditioning, and high‑fidelity audio. It runs from a wide supply range (about 10 V to 26 V total), is surface‑mount, and operates over –40°C to +125°C. Base device family: AD8620. Current stock available: 3300 pcs (subject to prior sale).

Key Features

Dual op amp (2 channels) in compact 8‑SOIC

JFET input, ultra‑low input bias current: about 3 pA

Low input offset voltage: about 45 µV (typical)

Gain bandwidth product: 25 MHz

Fast slew rate: about 60 V/µs (fast edges, low distortion)

Output drive: up to about 45 mA per channel

Supply current: about 3 mA per channel (~6 mA total)

Supply range: 10 V to 26 V total (for example, ±5 V to ±13 V)

Operating temperature: –40°C to +125°C

Mounting: surface mount (SMD)

Package: 8‑SOIC (0.154 in, 3.90 mm width)

Shipment format: Tube (other reel options available)

Category: ICs > Linear > Amplifiers > Instrumentation, Op Amps, Buffer Amps

Base product number: AD8620

Key Advantages

Handles high‑impedance sources cleanly due to ~3 pA bias current

High DC accuracy from low offset (~45 µV)

Wide 25 MHz bandwidth and ~60 V/µs slew rate for clean, fast signals

Strong output drive (up to ~45 mA) for heavier loads and long traces

Wide supply span fits ±5 V to ±13 V systems and 10–26 V single supplies

Two amplifiers in one SOIC to save board space and BOM cost

Thermal characteristics: governed by SOIC‑8 plastic package and PCB copper area; see datasheet for θJA/θJC. Good thermal design improves headroom and reliability.

Electrical properties (packaging‑related): MSL and ESD ratings vary by lot and finish; refer to the datasheet and product quality reports.

Lifecycle

Status: Active and widely used. Not near discontinuation to the best of current channel knowledge.

Direct equivalents and close alternatives:

- AD8620BRZ (Pb‑free version, same package/grade)

- AD8620AR/ARZ (same function in SOIC‑8, different grade/tolerance)

- AD8620BR‑REEL / AD8620BRZ‑REEL7 (tape‑and‑reel packing)

- Family single‑channel: AD8610AR/ARZ (not pin‑compatible; same family performance if one channel is needed)

- Functionally similar (not identical): TI OPA2134UA/OPA2134A (JFET audio, lower GBW), OPA1642 (low‑noise JFET, 11 MHz), OPA2604 (JFET audio). Check specs and pinouts before use.
