ADG441BR

ADG441BR is an Analog Devices device in the ADG family: a digitally controlled analog switch/multiplexer. It provides one or more low-leakage, low-on-resistance analog switches that let you route an analog signal under digital control. The BR suffix typically means RoHS-compliant (lead-free) packaging and tape-and-reel options.
Common uses include signal routing in instrumentation, front-end multiplexing for ADCs/DACs, and general test/measurement equipment where a compact, low-power analog switch is advantageous.
Key points to check in the datasheet:
- On-resistance and variation with temperature
- Off leakage currents
- Analog signal range relative to supply rails
- Supply voltage range and control logic thresholds
- Pinout and packaging details
For exact configuration (channel count, control interface, electrical specs), refer to the ADG441BR datasheet. If you’d like, I can summarize the spec table or point out typical operating ranges.

- Pin count: 8 pins (DIP-8 / SOIC-8)
- Function: Dual SPST (1-Form-A) analog switch with two bilateral pass elements used to route analog signals.

- Manufacturer: Analog Devices, Inc. (ADI).
- Company type: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing (DSP) integrated circuits.

ADG441BR is used for precise analog signal routing and multiplexing. Typical application areas:
- Data acquisition systems and instrumentation front-ends
- Test and measurement equipment
- Medical instrumentation and patient monitoring
- Automotive and industrial sensing and control
- Audio/video routing and switching
- Sensor interfaces and multiplexed front-ends in lab gear

ADG441BR comes in an 8-lead plastic SOIC package (SOIC-8).
