Product details

Quad Difet® op-amp — 35 V/µs slew rate in a through-hole DIP

The OPA404KP is a quad-channel, general-purpose operational amplifier from TI/Burr-Brown's Difet® series. It delivers a 6.4 MHz gain-bandwidth product and a 35 V/µs slew rate, with a FET input that holds input bias current to 1 pA. The 14-pin DIP package (0.300" width) and through-hole mounting suit it for prototyping, breadboard evaluation, and legacy board repairs where surface-mount rework is impractical. Supply range is 10 V to 36 V single or split, and the operating temperature covers 0°C to 70°C — commercial grade, not industrial or automotive.

Slew rate and input bias — what they mean for the signal chain

The OPA404KP slews at 35 V/µs. Each channel delivers 10 mA output current.

Frequently asked questions

What is an equivalent or alternative to OPA404KP?

A functional alternative is the OPA4374AIPWT, a quad CMOS op-amp in surface-mount (TSSOP) with rail-to-rail output, 6.5 MHz GBW, 5 V/µs slew rate, and 0.5 pA input bias. It operates from 2.7 V and covers -40°C to 125°C, but the package and supply range differ significantly from the OPA404KP's 14-DIP and 10–36 V span.
