AD642
FEATURES Matched Offset Voltage Matched Offset Voltage Over Temperature Matched Bias Current Crosstalk: - 124 d B @ 1 k Hz Low Bias Current: 35 p A max Warmed Up Low Offset Voltage: 500 ␮V max Low Input Voltage Noise: 2 ␮ V p-p High Open Loop Gain Low Quiescent Current: 2.8 m A max Low Total Harmonic Distortion Standard Dual Amplifier Pin Out Available in Hermetic Metal Can Package and Chip Form MIL-STD-883B Processing Available Single Version Available: AD542 Precision, Low Cost Dual Bi FET Op Amp AD642 PIN CONFIGURATION PRODUCT DESCRIPTION The AD642 is a pair of matched high speed monolithic Bi FET 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 p A max matched to 25 p A for the AD642K and L; 75 p A max, matched to 35 p A for the AD642J and S. In addition, the offset voltage is laser trimmed...
