Linear Technology LT1398/LT1399/LT1399HV Datasheet
The LT1398, LT1399 and LT1399HV are low‑power dual‑ and triple‑channel current‑feedback amplifiers with a 300 MHz bandwidth and fast shutdown capability. Each amplifier draws 4.6 mA when active and zero current when disabled, making them suitable for spread‑spectrum and portable equipment.
The devices operate from single or split supplies ranging from 4 V to –6 V (LT1398/LT1399) or up to –7.5 V (LT1399HV). They feature high slew rates (≈800 V/ms), short turn‑on (30 ns) and turn‑off (40 ns) times, and include individual enable pins for each channel.
