The Texas Instruments OPA2325IDR is a dual CMOS operational amplifier in an 8-SOIC package, combining a 10 MHz gain-bandwidth product with a 5 V/µs slew rate while drawing 650 µA per channel.
The 650 µA per channel supply current is the trade-off: you get enough speed for most precision analog front-ends without burning the power budget of a multi-channel data-acquisition board.
Yes, the OPA2325IDR features rail-to-rail output swing, allowing the output to reach close to the supply rails — useful when driving an ADC input or maximizing signal headroom at low supply voltages.
The OPA4374AIPWT is a quad CMOS op-amp with a similar 6.5 MHz GBW, 5 V/µs slew rate, and 0.5 pA input bias current, but in a TSSOP-14 package with four channels. It is not a pin-for-pin substitute in the 8-SOIC footprint, but it shares the same CMOS rail-to-rail topology and supply range for designs that can accommodate the larger package and extra channels.
