The AD644 is a pair of matched high speed monolithic FET input
operational amplifiers fabricated with the most advanced bipolar,
JFET and laser-trimming technologies. The AD644 offers
matched bias currents that are significantly lower than currently
available monolithic dual BiFET operational amplifiers: 35 pA
max, matched to 25 pA for the AD644K and L, 75 pA max
matched to 35 pA for the AD644J and S. In addition, the offset
voltage is laser trimmed to less than 0.5 mV, and matched to
0.25 mV for the AD644L, 1.0 mV and matched to 0.5 mV for
the AD644K, utilizing Analog Devices’ laser-wafer trimming (LWT) process.
