ADG722BRM

ADG722BRM Description

The ADG722BRM from Analog Devices Inc. is a high-performance, dual-channel SPST-NC (Single-Pole Single-Throw, Normally Closed) analog switch designed for precision signal routing in low-voltage applications. Operating within a 1.8V to 5.5V supply range, this IC delivers low on-resistance (4Ω max) and minimal leakage current (250pA max), ensuring high signal integrity. Its 200MHz bandwidth and fast switching characteristics (14ns Ton, 6ns Toff typ) make it suitable for high-speed data acquisition and communication systems. Packaged in an 8-pin MSOP, the ADG722BRM is ideal for space-constrained designs.

ADG722BRM Features

• Low On-Resistance: 4Ω max ensures minimal signal attenuation.
• Fast Switching: 14ns/6ns (Ton/Toff typ) enables high-speed operation.
• Low Leakage: 250pA max reduces power loss and improves accuracy.
• Wide Bandwidth: 200MHz -3dB bandwidth supports high-frequency signals.
• Low Charge Injection: 2pC minimizes distortion in precision circuits.
• Dual-Channel Design: Two independent SPST-NC switches in a compact 8MSOP package.
• Low Power Operation: Compatible with 1.8V to 5.5V supplies, ideal for battery-powered devices.
