Product details

3 MHz gain-bandwidth — where it fits in the signal chain

It operates from a 10 V to 30 V supply span and draws 2.5 mA per channel quiescent current.

The 10 V minimum supply means this part cannot run on a single 5 V rail; it needs at least ±5 V dual supplies or a single 10 V+ rail. The 10 mA per-channel output current is enough to drive a 2 kΩ load to within a couple of volts of the rails, but not a 50 Ω transmission line or a power transistor base without a buffer.

Package and temperature grade — board-fit and environment

Housed in an 8-TSSOP (also 8-MSOP compatible) package, surface-mount only.

Frequently asked questions

What is the slew rate of RC4558DGKRG4?

The slew rate is 1.7 V/µs. This limits large-signal bandwidth to roughly 270 kHz at 10 V output swing — adequate for audio and low-frequency control loops, but not for fast pulse or video applications.
