What this voltage-feedback amp brings to the signal chain
The LT1818CS8#TRPBF is a single-channel voltage-feedback amplifier from Analog Devices, packing a 400 MHz gain-bandwidth product and a 2500 V/µs slew rate into an 8-SOIC package. That slew rate means it can track a 5 V step in about 2 ns — relevant for driving high-speed ADC inputs or video lines where signal integrity at the edge matters more than the DC precision.
Supply rails, output drive, and temperature range
Runs on a supply span from 2.5 V to 12.6 V, drawing 9 mA quiescent current — the low minimum rail lets it work in 3.3 V systems without an extra regulator. Output can source or sink 70 mA per channel, enough to drive a 50-ohm back-terminated line or a moderate capacitive load without external buffer. Input offset voltage is 200 µV typical, input bias current 2 µA — the bias figure is higher than a FET-input amp, so source impedance above a few kOhm will add offset error that needs accounting in the gain stage. Temperature range is 0°C to 70°C commercial grade — not rated for industrial or automotive ambient, so keep it inside conditioned equipment or a ventilated enclosure.
Package, mounting, and lifecycle status
Housed in an 8-SOIC (0.154", 3.90 mm width) surface-mount package, supplier device package 8-SO — standard footprint, no thermal pad to route. Available in Tape & Reel (TR) or Cut Tape (CT) options — the TR suffix on this order code indicates reel packaging for automated pick-and-place.
