OPA2357AIDGSR

The OPA357 series of high-speed voltage-feedback CMOS operational amplifiers are designed for video applications and other applications requiring wide bandwidth. These devices are unity-gain stable and can drive large output currents. The differential gain is 0.02%, while the differential phase is 0.09°. The quiescent current is only 4.9 mA per channel. The OPA357 series of operational amplifiers are optimized for operation with single or dual supplies ranging from as low as 2.5 V (±1.25 V) to as high as 5.5 V (±2.75 V). The common-mode input range extends beyond the supply voltage range. The output swing is within 100 mV of the supply rails, supporting a wide dynamic range. The single-channel version (OPA357) comes in a small SOT23-6 package. The dual-channel version (OPA2357) is available in a VSSOP-10 package. The dual-channel version features fully independent circuits to minimize crosstalk and completely eliminate mutual interference. Both versions are rated for an extended operating temperature range of -40°C to +125°C.
