Product details

1300 V/µs — the number that tells you what this amp is for

The LT1223CS8#PBF is a single-channel current-feedback operational amplifier from Analog Devices, in an 8-pin SOIC package. Its headline spec is a 1300 V/µs slew rate, which puts it squarely in the territory of high-speed pulse amplification, video distribution, and deflection yoke drivers — applications where a voltage-feedback amp would slew-limit long before the signal reached its rated bandwidth. The current-feedback topology means the -3 dB bandwidth of 100 MHz stays flat across a wide range of closed-loop gains, unlike a conventional op-amp where gain and bandwidth trade off directly.

The supply span runs from 8 V minimum to 36 V maximum, so it works on ±15 V lab supplies or a single 12 V or 24 V rail without a regulator change. The quiescent current is 6 mA — not a micropower part, but reasonable for a high-speed stage. The temperature grade is commercial: 0°C to 70°C. That limits it to controlled indoor environments; if the board sits in an unventilated cabinet or near a motor drive, you'd want the industrial-temperature variant of this family. Input offset voltage is 1 mV typical, input bias current 1 µA — both typical for a current-feedback design and fine for AC-coupled paths.

Package and rework — 8-SOIC is technician-friendly

A standard hot-air nozzle at 300°C with a small tip lifts it clean in about 15 seconds. The land pattern is the same as any SO-8 — no hidden thermal pad, no exposed paddle to solder. If you're replacing a scorched part on a board, the chances of lifting a pad are low with reasonable iron technique.

Lifecycle — active, no LTB pressure

For a BOM line, this means you're not forced into a lifetime buy or a hurried redesign.

Frequently asked questions

Is LT1223CS8#PBF a current feedback amplifier?

Yes, it is a current-feedback (CFA) topology. This means the -3 dB bandwidth of 100 MHz is largely independent of the closed-loop gain setting, unlike a voltage-feedback amplifier where gain and bandwidth trade off.

What is the closest functional second-source for LT1223CS8#PBF?

Among the listed peers, the AD8008ARMZ is also a current-feedback amplifier with a 1000 V/µs slew rate and 500 MHz bandwidth, but it is a dual-channel part in a different package and temperature range. For a single-channel current-feedback replacement in the same speed class, the AD8008 is the closest functional match, though the pinout and package differ. The AD843JRZ-16 and AD847JRZ-REEL7 are voltage-feedback amplifiers and are not direct functional substitutes.
