Quad current-feedback amp with 320 V/µs slew rate
Its 320 V/µs slew rate and 245 MHz -3dB bandwidth target high-speed analog signal chains — video distribution, IF amplification, and pulse-processing front-ends where settling time and slew-induced distortion matter. The current-feedback topology keeps gain-bandwidth relatively flat across gain settings, so you get consistent phase margin from unity gain to about +10 V/V without external compensation.
Supply current and thermal budget
Each of the four amplifiers draws 1 mA (typical), totalling 4 mA quiescent for the package. At ±5 V supplies that is under 40 mW dissipation — manageable in a 14-SOIC without airflow. The 60 mA per-channel output current drives 50 Ω back-terminated lines or multiple ADC inputs directly. Input bias current is 1 µA (typical), which keeps DC offset errors low in high-impedance source applications.
Supply range and single-supply operation
The supply span runs from 4.5 V minimum to 11 V maximum. That covers single +5 V rails (common in 5 V logic systems) and dual ±5 V supplies. With a 5 V single supply the input common-mode range and output swing are limited by the current-feedback architecture — expect about 1.5 V headroom from each rail, so a 2 Vpp output swing is practical. Input offset voltage is 1.5 mV (typical), acceptable for most AC-coupled or closed-loop gain stages.
Lifecycle and sourcing posture
For BOM planning, there is no forced redesign window.
