●Product Details
●The ADA4177-1 single-channel, ADA4177-2 dual-channel, and ADA4177-4 quad-channel amplifiers feature low offset voltage (2 μV typical) and drift (1 μV/°C maximum), low input bias current, low noise, and low current consumption (500 μA typical). Outputs are stable with capacitive loads of more than 1000 pF with no external compensation.
●The inputs of the ADA4177-1/ADA4177-2/ADA4177-4 feature outstanding 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 these amplifiers include sensor signal conditioning (such as thermocouples, resistor thermal detectors (RTDs), and strain gages), process control front-end amplifiers, and precision diode power measurement in optical and wireless transmission systems.
●The ADA4177-1/ADA4177-2/ADA4177-4 operate over the −40°C to +125°C industrial temperature range. The ADA4177-1/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.
