Overview

Product Details

Demonstration circuit 2677A is a reference design for robust industrial data acquisition applications for the LTC®2358-18. The LTC2358-18 is capable of high voltage measurements with a large input common range; however, the DC2677A implements input protection that allows up to 400V of continuous input protection. Combined with gas discharge tubes, which provide protection from surges, the DC2677A is capable of surviving extreme abuse.

This reference design includes the LTC2358-18 SAR ADC, ADA4522-2 dual zero-drift operational amplifier, and an LT6658 dual-output, high current reference for sensor excitation.

The digital interface is an HSMC (high-speed mezzanine connector), which is compatible with Altera Cyclone V SoCkit and other Altera FPGA evaluation boards that support 3.3V CMOS I/O.
