AD642KH Datasheet PDF - ADI

●PRODUCT DESCRIPTION

●The AD642 is a pair of matched high speed monolithic BiFET operational amplifier fabricated with the most advanced bipolar, JFET and laser trimming technologies. The AD642 offers matched bias currents that are significantly lower than currently available monolithic dual FET input operational amplifiers: 35 pA max matched to 25 pA for the AD642K and L; 75 pA max, matched to 35 pA for the AD642J and S. In addition, the offset voltage is laser trimmed to less than 0.5 mV and matched to 0.25 mV for the AD642L, 1.0 mV and matched to 0.5 mV for the AD642K, utilizing Analog’s laser-wafer trimming (LWT) process.
