could you help choose a dual op amp with low offset voltage, small IB and small IQ suitable for smoke detectors. Specific requirements are as follows:
- Dual op amp, SOIC8 package;
- Voffset is less than 1mV, preferably less than 0.5V;
- IB is not more than 200pA, and it is better to be less than 50pA;
- The IQ of each channel does not 200μA;
- Support 3V single-ended power supply;
- The GBW is not less than 0.5MHz, and 1MHz or more is better.
