AD843AQ

AD843AQ Description

The AD843AQ from Analog Devices Inc. is a high-performance, general-purpose operational amplifier (op-amp) designed for precision analog applications. Housed in an 8-lead CERDIP package, this single-circuit op-amp delivers exceptional speed and accuracy with a 34 MHz gain bandwidth product (GBW) and a rapid 250V/µs slew rate. Its wide 9V to 36V supply voltage range and low 50 pA input bias current make it suitable for demanding industrial, medical, and instrumentation systems. The device operates with a 12mA supply current and offers a robust 50mA output current, ensuring reliable performance in high-gain or low-distortion circuits.
