The RE46C312 operational amplifier (op amp) has a very low input bias current of less than 6 pA at 60 °C with a low typical operating current of 600 nA, an offset voltage that is less than 1 mV and a gain bandwidth product of 10 kHz. The RE46C312 uses advanced CMOS technology, which provides high-speed operation, high open-loop gain, rail-to-rail input and rail-to-rail output swing. The RE46C312 operates with a single supply voltage that can be as low as 1.8V, while drawing less than 1.0 µA of quiescent current per amplifier. The RE46C312 is available in standard 8-lead PDIP and SOIC packages. This amplifier is ideal for high impedance low input bias current sensors such as ionization smoke detectors and pH electrodes, low-power battery-operated devices, and portable equipment.
