ADG419BRZ SPDT analog switch, low on-resistance IC
The ADG419BRZ is a monolithic CMOS SPDT (Single-Pole Double-Throw) analog switch from Analog Devices, designed for precision signal routing in low-voltage applications. It operates with a ±5V to ±20V dual supply or +5V to +36V single supply, featuring low on-resistance (35Ω typical) and fast switching speeds (tON: 150ns, tOFF: 100ns). The device ensures minimal distortion with <0.01% THD and supports rail-to-rail signal handling, making it ideal for high-accuracy systems. Encased in an 8-lead SOIC package, it is optimized for industrial temperature ranges (−40°C to +85°C) and offers TTL/CMOS-compatible logic inputs for easy integration.
ADG419BRZ Key Features
The ADG419BRZ excels with ultra-low power consumption (<0.1μA leakage current) and break-before-make switching to prevent signal shorts. Its 15pC charge injection and −3dB bandwidth of 200MHz ensure high-fidelity signal transmission. The switch’s ESD-protected inputs (≥2kV HBM) enhance reliability in harsh environments. Unlike mechanical relays, it provides solid-state durability with 10^9 switching cycles, reducing maintenance needs.
ADG419BRZ Applications
This IC is widely used in battery-powered devices, test equipment, and audio systems due to its low distortion. It serves in multiplexers, sample-and-hold circuits, and automated test systems (ATE), where precision switching is critical. Additional roles include communication routing (RF/IF signals), medical instrumentation, and industrial control systems requiring robust performance under voltage fluctuations.
Selection Advantages
The ADG419BRZ outperforms competitors with lower on-resistance vs. similar CMOS switches (e.g., DG419) and wider voltage range support compared to DG411-series alternatives. Its single-supply flexibility reduces external components, while low parasitic capacitance (<5pF) minimizes crosstalk in multi-channel designs. Engineers favor it for cost-effective replacements to electromechanical relays without sacrificing signal integrity.
Alternative Models
● DG419BRZ: Comparable SPDT switch but with higher on-resistance (45Ω) and slower switching.
● ADG1419: Offers lower RON (0.5Ω) for high-current apps but requires higher supply voltage.
● MAX4544: Features faster tON (50ns) but narrower voltage range (±15V).
● TS5A3357: Ultra-low-power (<1nA) alternative for battery-critical designs.
