Product details

Triple high-speed op-amp for video and ADC drive

The Texas Instruments OPA3680U/2K5 is a triple voltage-feedback operational amplifier from the SpeedPlus™ series, with three independent 1000 V/µs slew-rate channels in a 16-SOIC package.

A 1000 V/µs slew rate supports large-signal bandwidth into tens of megahertz. The 150 mA per-channel output current drives capacitive loads.

The 1 mV input offset voltage (typical) and 8 µA input bias current are typical for a high-speed voltage-feedback op-amp — not a precision amplifier. If your signal chain needs sub-millivolt DC accuracy, plan for a trim or a servo loop. The 8 µA bias current also means source impedance matters: a 1 kΩ source adds 8 mV of offset error, so keep the source impedance low or AC-couple.
