The Texas Instruments OPA4322SAIPW is a CMOS quad operational amplifier packing four rail-to-rail output stages in a single 16-TSSOP package. It delivers a 20 MHz gain-bandwidth product and a 10 V/µs slew rate, with an input bias current of just 0.2 pA — suited for high-impedance sensor interfaces, multi-stage active filters, and fast ADC drivers where you need four channels without giving up board area.
Yes — the output type is rail-to-rail, so the output swings within millivolts of both supply rails, maximising dynamic range at low supply voltages.
A close functional peer is the OPA4374AIPWT from TI — also a CMOS quad rail-to-rail op-amp in the same 16-TSSOP footprint, but with a 6.5 MHz GBW and 5 V/µs slew rate, so the OPA4322 is the faster choice for wider-bandwidth signal chains.
