3 Description
The OPAx354 series of high-speed, voltage-feedback CMOS operational amplifiers are designed for video and other applications requiring wide bandwidth. They are unity-gain stable and can drive large output currents. Differential gain is 0.02% and differential phase is 0.09°. Quiescent current is only 4.9 mA per channel.
The OPAx354 series of op amps are optimized for operation on single or dual supplies as low as 2.5 V (±1.25 V) and up to 5.5 V (±2.75 V). Common-mode input range extends beyond the supplies. The output swing is within 100 mV of the rails, supporting wide dynamic range.
For applications requiring the full 100-mA continuous output current, single and dual 8-pin HSOP PowerPAD versions are available.
The single version (OPA354) is available in the tiny 5- pin SOT-23 and 8-pin HSOP PowerPAD packages. The dual version (OPA2354) comes in the miniature 8-pin VSSOP and 8-pin HSOP 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.
