AD746SQ

AD746SQ Description

The AD746SQ from Analog Devices Inc. is a high-performance, dual-channel JFET-input operational amplifier housed in an 8-pin CERDIP package. Designed for precision analog applications, it operates over a wide supply voltage range of 9V to 36V, making it versatile for industrial and instrumentation systems. With a -3dB bandwidth of 13 MHz and a slew rate of 75V/µs, it delivers fast signal processing with minimal distortion. The JFET input stage ensures ultra-low input bias current (110 pA) and low input offset voltage (300 µV), critical for high-impedance sensor interfaces and precision DC amplification.
