Three SPDT switches in a 16-pin QSOP
The MAX4560EEE+ from Analog Devices packs three independent SPDT switch circuits into a 16-QSOP package. Each switch routes a common terminal to one of two inputs, giving a 2:1 multiplexer per channel. The part runs on a single supply from 2V to 12V or dual supplies from ±2V to ±6V. The -93dB crosstalk at 100kHz is the headline figure here — that is good isolation for audio-frequency analog multiplexing, signal routing, or data acquisition front-ends where you do not want channel bleed. The 150ns turn-on and 120ns turn-off times keep up with moderate-speed analog sampling and digital control signals.
Package and mounting
160Ω max on-resistance is moderate — fine for routing audio, control voltages, or digital logic, but not for precision low-impedance paths like power rails or high-current sensor bridges. The 2Ω channel-to-channel matching means the three switches track each other closely, handy for gain-setting or filter networks where resistor matching matters. Charge injection of 2.4pC is low enough that sample-and-hold circuits and precision analog muxes will not see significant glitch energy. Leakage current maxes out at 1nA off-state, so it will not load down high-impedance sources. The -40°C to +85°C temperature range covers industrial environments — motor drives, outdoor telecom, factory automation panels. The 16-QSOP body is roughly 3.9mm wide, a compact footprint for dense boards.
Sourcing and lifecycle
The part ships in a Tube carrier — 16-QSOP surface-mount package, ROHS3 compliant.
