3 Description
The OPA357 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 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 OPA357 series of op amps is 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.
The single version (OPA357) comes in the miniature SOT23-6 package. The dual version (OPA2357) is offered in the VSSOP-10 package.
The dual version features completely independent circuitry for lowest crosstalk and freedom from interaction. Both versions are specified over the extended –40°C to +125°C temperature range.
