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.
APPLICATIONS
- Wireless base station control circuits
- Optical network control circuits
- Instrumentation
- Sensors and controls
- Thermocouples, RTDs, strain gages, shunt current measurements

Design Tools
OpAmp Error Budget Calculator
An online tool to illustrate range, gain and accuracy issues with Op Amp.
Analog Filter Wizard
Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.
Analog Photodiode Wizard
Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.
