Product Details

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.
