Frequently Asked Questions
What is the input bias current specification of the OPA602BP and why does it matter for charge amplifier designs?
The OPA602BP achieves a maximum input bias current of only 2 pA at 25°C, making it one of the lowest-leakage FET-input op-amps available in a DIP package. In charge amplifier and electrometer designs, even 10 pA of bias current causes voltage drift across large feedback capacitors, so the 2 pA specification ensures measurement accuracy is maintained over seconds or minutes of integration time.
How does the OPA602BP's CMRR and input offset voltage support high-accuracy differential measurement applications?
The OPA602BP provides a typical CMRR of 100 dB and a minimum of 88 dB, combined with a maximum input offset voltage of 1 mV. This combination allows it to reject common-mode noise by a factor of 100,000:1 while contributing less than 1 mV of DC error, making it suitable for precision bridge transducer interfaces, strain gauge amplifiers, and differential analog-to-digital converter front-ends requiring sub-millivolt accuracy.
When is OPA602BP a preferred choice over CMOS op-amps in legacy precision instrumentation designs?
The OPA602BP is preferred in legacy precision instrumentation where DIP-8 through-hole socketed components are required for field replacement or prototyping, and where Difet FET-input technology provides better bias current stability across temperature than CMOS inputs. Its 2 pA bias current and 88 dB minimum CMRR maintain performance across industrial temperature ranges, making it a reliable drop-in for existing instruments that cannot migrate to surface-mount CMOS alternatives.
