1.4 GHz CFA in a SOT-23-6 — what the ratings mean for your signal chain
The EL5166IWZ-T7A is a single-channel current-feedback operational amplifier from Renesas Electronics, specified for a -3dB bandwidth of 1.4 GHz and a slew rate of 6000 V/µs. That slew rate — 6000 V/µs — means the output can swing rail-to-rail on a 5 V supply in under 1 ns, so the part is sized for video line drivers, high-speed ADC front-ends, or pulse amplification where the edge rate must stay clean above 100 MHz. The current-feedback topology decouples gain-bandwidth from the closed-loop gain setting, so you can set a gain of 10 without the bandwidth collapse you would see in a voltage-feedback amp at this speed. Output current is rated 200 mA per channel — enough to drive a 50-ohm back-terminated cable directly or a moderate capacitive load without an external buffer.
Supply span, package, and temperature grade
Operating from a single supply span of 5 V to 12 V, the part covers standard 5 V and 12 V rails used in mixed-signal and RF boards. Housed in a SOT-23-6 package (supplier device package 6-SOT), it mounts on a standard surface-mount footprint and is specified for the industrial temperature range of -40°C to +85°C. The -40°C to +85°C range covers most base-station, test-equipment, and industrial control environments — not automotive under-hood, but fine for indoor and outdoor sheltered gear.
Active lifecycle and compliance
Available in Tape & Reel (TR) or Cut Tape (CT) packaging — the T7A suffix identifies the reel quantity and tape format, so confirm the exact ordering code matches your pick-and-place feeder requirement.
