ADG712BR

ADG712BR Description

The ADG712BR from Analog Devices Inc. is a high-performance, 4-channel SPST (Single-Pole Single-Throw) analog switch designed for precision signal routing in low-voltage applications. Housed in a 16-pin SOIC package, this obsolete but still relevant IC offers low on-resistance (4Ω max) and ultra-low leakage current (100pA max), making it ideal for high-accuracy systems. Operating from 1.8V to 5.5V, it supports a wide range of supply voltages while delivering 200MHz bandwidth and fast switching speeds (11ns turn-on, 6ns turn-off). Its low charge injection (3pC) and minimal channel capacitance (10pF off-state) ensure minimal signal distortion, critical for data acquisition and communication systems.

ADG712BR Features

• Low On-Resistance: 4Ω max ensures minimal signal attenuation.
• Fast Switching: 11ns (Ton), 6ns (Toff) enables high-speed signal routing.
• Wide Voltage Range: 1.8V to 5.5V compatibility for versatile designs.
• Low Leakage: 100pA max for precision applications.
• High Bandwidth: 200MHz -3dB supports high-frequency signals.
• Minimal Distortion: 3pC charge injection and 10pF off-capacitance preserve signal integrity.
• Robust Packaging: 16-SOIC with MSL1 (Unlimited) moisture sensitivity for reliable assembly.

ADG712BR Applications

• Data Acquisition Systems: Low leakage and high bandwidth ensure accurate signal sampling.
• Battery-Powered Devices: Operates efficiently at low voltages (1.8V).
• Audio/Video Switching: Fast switching and low distortion maintain signal fidelity.
• Test & Measurement Equipment: Precision switching for multiplexed sensor inputs.
• Communication Systems: High bandwidth supports RF and baseband signal routing.

Conclusion of ADG712BR

The ADG712BR excels in low-voltage, high-precision applications where signal integrity, speed, and low power are critical. Though marked obsolete, its low on-resistance, fast switching, and minimal distortion make it a strong choice for legacy or niche designs requiring reliable analog switching. Ideal for portable electronics, test systems, and communication hardware, it balances performance with versatility in a compact SOIC package.
