The AD546KN from Analog Devices is a monolithic electrometer operational amplifier designed for applications requiring minimal input bias current and low input offset voltage. It features a maximum input bias current of 1 pA and a maximum input offset voltage of 1 mV. The amplifier boasts a slew rate of 3 V/ms and a unity gain bandwidth of 1 MHz.
Utilizing "topgate" JFET technology, the AD546KN achieves significantly reduced input bias currents. Its bootstrapped input stage provides a high common-mode impedance, ensuring input bias current remains largely independent of common-mode voltage variations. This makes it suitable for buffer amplifier applications with current output transducers like photodiodes and pH probes, as well as precision integrators or low droop rate sample-and-hold amplifiers.
The AD546KN is available in a cost-effective, 8-pin plastic Mini-DIP package, compatible with standard op-amp pinouts and suitable for automatic insertion equipment. It operates within the 0°C to +70°C commercial temperature range.
