Product details

500 V/µs slew rate, 85 MHz bandwidth — single voltage-feedback amplifier in SC-70-6

The MAX4390EXT+T is a single-channel voltage-feedback op-amp from Analog Devices, specified for a slew rate of 500 V/µs and a -3 dB bandwidth of 85 MHz. Supply voltage range is 4.5 V to 11 V single supply, or ±2.25 V to ±5.5 V dual supply. The quiescent current is 6 mA per channel, and the output can deliver 95 mA per channel — enough to drive a 75 Ω video line or a moderate capacitive load without external buffer.

SC-70-6 footprint — design-in checklist for the layout engineer

Packaged in a 6-lead SC-70-6 (also known as SOT-363), the MAX4390EXT+T occupies roughly 2.0 mm × 2.1 mm of board area. The part is surface-mount only. The tape-and-reel suffix (+T) means it ships on 7-inch reels; cut-tape quantities are available for prototyping. Confirm the reel orientation matches your pick-and-place feeder — the SC-70-6 pocket orientation is standard EIA-481.

ROHS3 compliance covers the full substance restriction list including the four phthalates — no exemption expiry to track. The SC-70-6 package is a standard Analog Devices offering, so allocation risk is low for volume orders.

Frequently asked questions

Is MAX4390EXT+T a direct replacement for MAX4390EXT?

The MAX4390EXT+T is the tape-and-reel variant of the base MAX4390EXT. The electrical specifications are identical. The +T suffix indicates reel packaging; the base part number without suffix is typically supplied in tubes or bulk. Confirm your assembly house accepts reel packaging before substituting.

What is the closest pin-compatible alternative to MAX4390EXT+T?

Within the same Analog Devices family, the MAX4390 series shares the same pinout and SC-70-6 footprint. The MAX4391 is a dual-channel variant with the same 500 V/µs slew rate and 85 MHz bandwidth, but it is not pin-compatible because it uses an 8-pin package. For a single-channel drop-in, the MAX4390EXT+T is the only ordering code in this package.
