The single ADA4077-1, dual ADA4077-2, and quad ADA4077-4 amplifiers feature extremely low offset voltage and drift, and low input bias current, noise, and power consumption. Outputs are stable with capacitive loads of more than 1000 pF with no external compensation.

Applications for this amplifier include sensor signal conditioning (such as thermocouples, resistance temperature detectors (RTDs), strain gages), process control front-end amplifiers, and precision diode power measurement in optical and wireless transmission systems. The ADA4077-1/ADA4077-2/ADA4077-4 are useful in line powered and portable instrumentation, precision filters, and voltage or current measurement and level setting.

Unlike other amplifiers, the ADA4077-1/ADA4077-2/ADA4077-4 have an MSL1 rating that is compliant with the most stringent of assembly processes, and they are specified over the extended industrial temperature range from −40°C to +125°C for the most demanding operating environments.

APPLICATIONS

  • Process control front-end amplifiers 
  • Optical network control circuits
  • Instrumentation
  • Precision sensors and controls
  • Precision filters

Product Detail

The EVAL-KW4502Z is a demonstration board for evaluating the low-frequency noise of three general operational amplifiers (op amp): (1) low power op amp, (2) low noise, bipolar op amp, and (3) low noise, zero drift op amp.

The EVAL-KW4502Z uses ADA4510-2 which is a dual-channel, 40 V, high precision, low input bias current, low offset voltage, low offset voltage drift, low noise, rail-to-rail input and output operational amplifier that can be used at any point of the signal chain, including sensing, conditioning, and output drive. More importantly, it can operate in low voltage supplies as +/-5V that can be provided by the ADALM2000 Active Learning Module.

The EVAL-KW4502Z accommodates LT1782, ADA4077, and ADA4522 in a thin small outline transistor (TSOT), standard small outline package (SOIC), and mini small outline package (MSOP), respectively.

Full specifications on the LT1782, ADA4077, and ADA4522 are available on the Analog Devices, Inc. website.
