ADG419TQ Description

Short technical summary and product information.

The ADG419TQ is a precision LC2MOS SPDT analog switch designed for low power and high performance. It offers a single-pole double-throw configuration with break-before-make switching action. Key specifications include a maximum on-resistance of 35 ohms, a supply voltage range up to 44V, and a fast transition time of 160 ns. The device operates over the full military temperature range of -55°C to +125°C. With ultralow power dissipation below 35 µW, the ADG419TQ is ideal for battery-powered and portable instruments. The switch exhibits very flat on-resistance over the analog signal range (VSS to VDD), ensuring excellent linearity and low distortion. Leakage currents are typically 250 pA. The ADG419TQ is offered in a hermetically sealed 8-lead CERDIP package (8-CDIP, 0.300" width) for through-hole mounting. It is a direct plug-in replacement for the DG419. Applications include precision test equipment, sample-and-hold systems, and instrumentation where low power and high accuracy are required.
