The MAX349CAP+ is a high-performance, single-ended, 8-channel analog multiplexer from Maxim Integrated that offers precision signal routing for complex analog signals in a wide range of applications. Designed to operate with a single +5V supply or dual ±15V supplies, this versatile component provides the flexibility needed for both portable and industrial applications.
With its low on-resistance (<35 ohms) and low charge injection (<10pC), the MAX349CAP+ ensures minimal signal distortion and high signal integrity, making it an ideal choice for data acquisition systems, test equipment, and communication systems. The device's high off-isolation (>70dB at 1MHz) and crosstalk (<−90dB at 1MHz) specifications ensure that signals are switched with high precision and minimal interference from adjacent channels.
The MAX349CAP+ is equipped with an industry-standard 16-pin narrow SO package, which not only saves space on the PCB but also allows for easy integration into existing designs. The multiplexer's digital inputs are TTL/CMOS logic compatible, making it easy to control with a wide range of microcontrollers and logic devices.
In addition, the MAX349CAP+ features break-before-make switching, which prevents momentary shorting of adjacent channels during switching. This feature is particularly important in applications where signal integrity is critical. The device also includes an inhibit input to simultaneously open all signal paths, providing a convenient method for disabling the device during power-up or other system states.
Maxim Integrated's commitment to quality and reliability is evident in the MAX349CAP+, which is specified over the extended industrial temperature range (-40°C to +85°C). This ensures reliable operation in harsh environments and under varying temperature conditions. Whether you're designing a precision measurement instrument or a robust industrial control system, the MAX349CAP+ is an excellent choice for your analog multiplexing needs.
