8:1 analog multiplexer for precision signal routing
The Analog Devices MAX4051ESE+T is a single-pole 8-throw (8:1) CMOS analog multiplexer/demultiplexer in a 16-SOIC package. It routes one of eight input channels to a common output, or demultiplexes a single input across eight outputs. The part operates from a single 2V to 16V supply or dual ±2.7V to 8V supplies, suiting it for both single-rail and split-rail analog systems. With a maximum on-resistance of 100Ohm and channel-to-channel matching within 12Ohm, it maintains signal fidelity across channels. The -90dB crosstalk at 100kHz makes it a clean choice for multiplexing audio, instrumentation, or data-acquisition signals where channel isolation matters.
Turn-on time is 175ns max, turn-off 150ns max, which keeps channel switching fast enough for scanned analog inputs in moderate-speed data-acquisition systems. Charge injection is rated at 2pC — low enough that sample-and-hold droop or glitch energy stays manageable in precision circuits. Off-leakage current is 1nA max, and channel capacitance is 2pF on both source and drain sides, so the multiplexer loads the signal path minimally. These specs together mean the MAX4051ESE+T fits well in applications like analog input multiplexing for ADCs, audio routing, or test-equipment front-ends where settling time and signal integrity are the constraints.
Package, temperature grade, and compliance
The part is surface-mount in a 16-SOIC package (0.154" width, 3.90mm body), with the supplier device package also listed as 16-SOIC. ROHS3 compliant.
