What this part is and where it fits
The Analog Devices MAX308CSE+T is a single 8:1 analog multiplexer in a 16-SOIC surface-mount package. It routes one of eight analog inputs to a common output, controlled by three address lines and an enable. The 100 Ohm max on-resistance is low enough for most audio and low-frequency signal chains without adding noticeable attenuation, and the 150 ns turn-on/turn-off time keeps up with moderate-speed data acquisition or test equipment switching. It runs on a single supply from 5V to 30V, or dual supplies from ±5V to ±20V, which makes it adaptable to systems with existing ±15V analog rails or a single 12V or 24V industrial supply. The crosstalk of -92 dB at 100 kHz means channel bleed is well suppressed for audio or low-level sensor multiplexing. Charge injection is 2 pC, so glitch energy during switching is small enough to avoid upsetting a downstream sample-and-hold in most designs.
Temperature grade and environment
Rated for the commercial temperature range of 0°C to 70°C, this part is suited for indoor equipment, office electronics, benchtop instruments, and other controlled environments. It is not specified for industrial or automotive use where the ambient may dip below freezing or exceed 70°C.
Package and supply details
Housed in a 16-SOIC with 3.90 mm body width (the narrow SOIC-16 footprint), it is a common, easy-to-solder package for reflow or hand assembly. Surface-mount only — no through-hole option.
Sourcing and availability
The MAX308CSE+T is an active, production-part number from Analog Devices. It is sourced through independent distribution and quoted to order against an RFQ.
