概述
Description
ADG721BRM is Analog Devices’ single-channel, voltage-controlled analog switch. It provides a low-impedance path between input and output when ON and a high-impedance path when OFF, enabling easy routing of analog signals in mixed-signal designs. The BRM suffix denotes the RoHS-compliant package (compact MSOP-8/leadframe style). Designed for low power and wide-supply operation, it’s suitable for instrumentation, sensor interfaces, audio paths, and data-acquisition systems. Key characteristics typically include low on-resistance, low leakage, and fast switching, controlled by a digital logic input. For exact electrical specs, timing, package pinout, and operating ranges, consult the ADG721 family datasheet.
Features
ADG721BRM is an 8-channel, monolithic SPST analog switch array from Analog Devices. Key features:
- 8 independent single-pole, single-throw (SPST) analog switches in one device
- Wide supply range and rail-to-rail analog path (typical 2.7 V–5.5 V)
- Low on-resistance and low leakage when OFF
- Break-before-make switching to prevent signal overlap
- Small signal routing with low charge injection and fast switching
- 16-pin MSOP (BRM) package option
- Industrial temperature range (roughly -40°C to +85°C)
- ESD protection on I/O pins
- Suitable for signal routing, multiplexing, and instrumentation applications
Note: For exact electrical characteristics (RON, leakage, isolation, control logic, timing, and packaging details), please refer to the official datasheet.
