概述

Description

ADG441BR is an Analog Devices CMOS analog switch from the ADG441/ADG442 family. It provides two independent analog switches in an 8-pin package, allowing you to route or disconnect two analog signals under digital control. The BR suffix denotes RoHS-compliant, tape-and-reel packaging. Typical use cases include signal routing in instrumentation, data acquisition, audio, and portable electronics.
Key points:
- Dual-channel analog switch (two SPST-type paths) with a common or individual control, depending on variant.
- Operates from a single supply in the low-voltage range (approximately 2.7 V to 5.5 V).
- Low on-resistance and low leakage, suitable for modest signal paths.
- Fast switching with typical protection features to handle ordinary analog signals.
For exact specifications (R_on values, leakage, control logic levels, voltage ranges, pinout) and package options, refer to the latest ADG441/ADG442 datasheet.

Features

Here are typical features for the ADG441BR (Analog Devices) analog switch:
- One-channel CMOS analog switch (SPST) in an 8-pin package (BR variant)
- Break-before-make operation
- Low on-resistance (RDS(on)) when ON
- Very low leakage off-state
- Wide supply range (compatible with common logic and analog rails)
- Rail-to-rail analog signal handling
- Logic-level control input (CMOS/TTL compatible)
- Fast switching with low charge injection
- Suitable for signal routing with good isolation
- ESD protection and robust safeguard features
- RoHS-compliant packaging (BR suffix)
Note: Exact numbers (RDS(on), leakage, supply range, temp range) vary by sub-version. For precise values, consult the current ADG441BR datasheet.

Package

ADG441BR is in an 8‑lead SOIC (surface‑mount) package, Pb‑free (RoHS compliant).

Pinout

ADG441BR has 8 pins (SOIC-8). It is a single-channel, 1-Form-A (normally open) bidirectional analog switch: it provides one A–B analog path that closes (conducts) when the control input is activated, and opens (disconnected) when it is not.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
