Dual CMOS amplifier for precision signal chains
The 0.1 pA input bias current is essential for high-impedance sources like photodiode transimpedance amplifiers or pH probe buffers — a bipolar-input op-amp with nanoamp bias would add an error term that swamps the signal. For a battery-powered design, the 1.3 mA total supply current for both channels keeps the power budget tight while still providing 66 mA output drive per channel to drive an ADC input or a cable.
Housed in a 10-VSSOP (also known as 10-MSOP with 0.118" body width), this surface-mount package fits dense mixed-signal boards where every mm² counts.
The OPA4374AIPWT is a quad CMOS amplifier with similar 0.5 pA bias and 5 V/µs slew rate, but it is not a pin-compatible second source; the LMP7712MME/NOPB remains the direct fit for a dual-channel 10-VSSOP footprint.
