The OPAx354 series of high-speed, voltage-feedback CMOS operational amplifiers is designed for video and other applications requiring wide bandwidth. These devices are unity-gain stable and drive large output currents. Differential gain is 0.02% and differential phase is 0.09°. Quiescent current is only 5mA per channel.
The OPAx354 series of op amps is optimized for operation on single or dual supplies as low as 2.5V (±1.25V) and up to 5.5V (±2.75V). Common-mode input range extends beyond the supplies. The output swing is within 100mV of the rails, supporting a wide dynamic range.
For applications requiring the full 100mA of continuous output current, single and dual 8-pin HSOIC (SO PowerPAD) versions are available.
The single version (OPA354) is available in tiny 5-pin SOT-23 and 8-pin HSOIC (SO PowerPAD) packages. The dual version (OPA2354) comes in miniature 8-pin VSSOP and 8-pin HSOIC (SO PowerPAD) packages. The quad version (OPA4354) is offered in 14-pin TSSOP and 14-pin SOIC packages.
Multichannel version features completely independent circuitry for lowest crosstalk and freedom from interaction. All features are specified over the extended –40°C to +125°C temperature range.
