What this op-amp is and where it fits
The LT1028ACN8#PBF is a single-channel general-purpose op-amp from Analog Devices in an 8-DIP through-hole package. It delivers a 75 MHz gain-bandwidth product and a 15 V/µs slew rate, making it a solid choice for fast signal conditioning, active filters, and precision instrumentation where you need wide bandwidth without moving to a dedicated high-speed amplifier. The 10 µV input offset voltage keeps DC errors low, so you can skip the trim pot in many circuits. Supply range runs from 8 V to 36 V single or split, and quiescent current is 7.4 mA — not a micropower part, but reasonable for the performance. Operating temperature is 0°C to 70°C, so this is a commercial-grade device for indoor equipment, lab gear, and production test fixtures.
Package and mounting — field-service friendly
This comes in an 8-pin DIP (0.300" body width, 7.62 mm pitch) and ships in a tube. Through-hole mounting means you can socket it — no hot-air station needed. If you are troubleshooting a board on site, you can swap this part with a standard IC puller in under a minute. Orientation is obvious: pin 1 is marked with a notch and a dot on the package body. No fine-pitch soldering, no paste stencil, just a clean swap.
Lifecycle and sourcing
The LT1028ACN8#PBF is listed as Active by the manufacturer and is ROHS3 compliant. No end-of-life notice, no last-time-buy pressure. This part is sourced through independent distribution and quoted to order against an RFQ.
