The MAX351EPE+ is a member of Maxim Integrated\'s MAX351 series of analog switch arrays, offering up to 8 channels of bidirectional switching. Designed to operate single-ended, the switch array offers the possibility of multiple independent switches in a single package, supporting a wide range of applications. The Dual-in-Line subset in particular provides excellent versatility and cost-savings when interfacing analog signals in industrial, medical, or automotive applications.

The MAX351EPE+ has an operating voltage range of -8V to +8V, with a non-linear voltage transfer characteristic, and supports supply voltages up to +18V. Using a low on-resistance of 0- 60Ω for the switches, the signal path is heavily protected by an independent ESD protection network. An on-chip driver has been incorporated to provide driving capability for a wider range of signals, from simple signal levels to high-voltage switches.

The device is uniquely suited to applications requiring a number of high-performance switches in a single package. For example, the active PID controller loop can be implemented as described in Figure 1 below. The temperature of a heat exchanger is measured and fed to the A/D converter, in order to determine set of PID coefficients and the reference temperature. The controller then reads this data and produces an output signal based on these values. This output is then sent to an output stage, which uses the MAX351EPE+ to control the switching of a heat source. This control loop is then repeated in order to regulate the heat source to the desired temperature.

In addition to providing deterministic temperature control, the MAX351EPE+ can also be used for applications involving multiplexing and demultiplexing of data signals. By using its on-chip drivers, signals from different channels can be quickly and easily multiplexed and demultiplexed with minimal effort. Moreover, since the device has an ESD protection network built in, it can be used in industrial or automotive scenarios without fear of damage to the signal.

The MAX351EPE+ is a versatile switching device with a variety of applications in analog signal control and data multiplexing and demultiplexing. Its ability to support single-ended voltage ranges, coupled with its integrated driver and ESD protection network, make it an ideal choice for industrial, medical, and automotive applications. Furthermore, with its low on-resistance characteristics and its excellent signal protection, the MAX351EPE+ is sure to deliver the reliable performance that customers have come to expect.
