The ADA4522-1 / ADA4522-2 / ADA4522-4 are single/dual/quad channel, zero drift op amps with low noise and power, ground sensing inputs, and rail-to-rail output, optimized for total accuracy over time, temperature, and voltage conditions. The wide operating voltage and temperature ranges, as well as the high open-loop gain and very low dc and ac errors make the devices well suited for amplifying very small input signals and for accurately reproducing larger signals in a wide variety of applications.

The ADA4522-1 / ADA4522-2 / ADA4522-4 performance is specified at 5.0 V, 30 V, and 55 V power supply voltages. These devices operate over the range of 4.5 V to 55 V, and are excellent for applications using single-ended supplies of 5 V, 10 V, 12 V, and 30 V, or for applications using higher single supplies and dual supplies of ±2.5 V, ±5 V, and ±15 V. The ADA4522-1 /  ADA4522-2 / ADA4522-4 use on-chip filtering to achieve high immunity to electromagnetic interference (EMI).

The ADA4522-1 / ADA4522-2 / ADA4522-4 are fully specified over the extended industrial temperature range of −40°C to +125°C and are available in 8-lead MSOP, 8-lead SOIC, 14-lead SOIC, and 14-lead TSSOP packages.

APPLICATIONS

  • Inductance, capacitance, and resistance (LCR) meter/megohmmeter front-end amplifiers
  • Load cell and bridge transducers
  • Magnetic force balance scales
  • High precision shunt current sensing
  • Thermocouple/resistance temperature detector (RTD) sensors
  • Programmable logic controller (PLC) input and output amplifiers

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.
