The inputs of the ADA4177-1, ADA4177-2, and ADA4177-4 set a new standard in precision amplifier robustness, providing input protection against signal excursions 32 V beyond either supply, as well as 70 dB of rejection for electromagnetic interference (EMI) at 1000 MHz. Applications for this amplifier include sensor signal conditioning (such as thermocouples, RTDs, and strain gages), process control front-end amplifiers, and precision diode power measurement in optical and wireless transmission systems.
The ADA4177-2 and ADA4177-4 operate over the -40°C to +125°C industrial temperature range. The ADA4177-1 and the ADA4177-2 are available in an 8-lead SOIC package and an 8-lead MSOP package. The ADA4177-4 is available in a 14-lead TSSOP and a 14-lead SOIC package.
