With single, dual, and quad versions, they all offer ±32 V input over voltage protection (OVP) on-chip, leading to a reduced bill of materials cost and board space by eliminating the need for external OVP discretes. With the dual advantage of simplifying system design and making the end system easier to pass EMI susceptibility testing by including integrated EMI filtering on inputs, the parts meet an impressive 70 dB of rejection at 1000 MHz. For precision instrumentation, end systems can be made smaller due to the integrated OVP and EMI. There is no need to calibrate the system over time or temperature change leading to increased uptime and reduced cost of ownership. This is due to the ultralow offset voltage and drift specifications. For the ultimate end system precision and linearity, features such as the rail-to-rail output adds value for designers that need additional dynamic range to measure the smallest level signals. Low noise performance complemented by excellent dc precision and ac accuracy specifications minimize the need for design trade-offs, especially for small form factor end systems where low power dissipation is needed. For process control sensor interfaces such as thermocouples, RTDs, and strain gages, the sensor may be off board exposing the op amp inputs to overvoltage and EMI. Therefore, the on-chip robust protection is a key advantage in space constrained modules. The ADA4177 family robust inputs combined with low supply current and consistent specification over a wide range allows them to be used as input module front-end amplifiers with signal swings compatible to industry standards, and especially for small form factor, USB-powered applications where low power and small packages are critical. The drive for increased productivity within all industrial environments is driving PCL and DCS systems to incorporate more and more channels to facilitate more process node monitoring. The multichannel versions lead to greater efficiencies within the end system, which ultimately lower the cost of the system and simplify design.
