Single J-FET op-amp in a hermetic CERDIP package
The AD745AQ from Analog Devices is a single J-FET input operational amplifier in an 8-pin CERDIP package. It delivers a 12V/µs slew rate and 20 MHz gain-bandwidth product, with a 250 µV input offset voltage and 150 pA input bias current. The supply range spans 9.6 V to 36 V, and the output can source or sink 40 mA. This is a through-hole part rated for 0°C to 70°C commercial environments.
12V/µs slew rate and 20 MHz GBW — signal chain fit
The 12V/µs slew rate and 20 MHz gain-bandwidth product suit this amplifier for fast signal conditioning, active filters, and data acquisition front-ends where settling time matters. The J-FET input stage keeps bias current at 150 pA, important for high-impedance sensor interfaces.
