Active production, precision analog switching
The Analog Devices MAX329EWE+T is a precision SP4T (single-pole, four-throw) analog switch with two independent circuits in a 16-SOIC package. It switches analog or digital signals up to the supply rails with a maximum on-resistance of 3.5kOhm and channel-to-channel matching of 70Ohm — tight enough for multiplexing sensor inputs or gain-setting resistors where the absolute R_on matters less than the ratio between channels. Charge injection is rated at 2pC typical, and off-leakage maxes out at 10pA, so it won't glitch a sample-and-hold capacitor or bleed down a high-impedance node. The supply range accepts either a single +10V to +30V rail or dual ±5V to ±18V rails, which covers the ±15V supplies common in ATE and bench instrumentation.
Package and mounting
The wide SOIC footprint is common for multi-channel analog switches and op-amps, so it fits a standard PCB land pattern without surprises.
