Product details

Dual op-amp for signal conditioning and audio stages

Each of the two channels draws 2.5 mA supply current, which keeps the total quiescent draw under 5 mA for the package — a reasonable trade-off for the 3 MHz GBW in multi-channel boards where thermal budget matters.

The RC4558IPWR operates from a 10 V to 30 V total supply span, which covers the common ±5 V to ±15 V split-rail configurations used in industrial signal chains. The differential output type and 10 mA per-channel output current let it drive moderate loads — think ADC input buffers or headphone pre-drivers — without an external buffer stage. For a general-purpose op-amp these are within the expected range; if your application demands sub-100 µV Vos, a precision amplifier like the OPAx188 family would be a tighter fit.

Housed in an 8-TSSOP (4.40 mm width) with a 0.65 mm pin pitch, this part is a drop-in for any dual op-amp layout using that footprint.

Frequently asked questions

What is the difference between RC4558IPWR and RC4558P?

The primary difference is the package: RC4558IPWR comes in an 8-TSSOP surface-mount package, while RC4558P is in a through-hole PDIP package. Both share the same dual general-purpose op-amp core with 3 MHz GBW and 1.7 V/µs slew rate. The choice depends on your assembly process — reflow for TSSOP vs wave solder or socket for PDIP.

What is the slew rate of RC4558IPWR?

The slew rate is 1.7 V/µs. This limits large-signal bandwidth — a 10 V peak-to-peak output swing can be reproduced up to approximately 54 kHz before slew-induced distortion appears.
