OPA357 具有关断状态的 250MHz 轨至轨 I/O 单路 CMOS 运算放大器
The OPA357 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 4.9mA per channel.
The OPA357 series op amps are 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 wide dynamic range.
For applications requiring the full 100mA continuous output current, the single SO-8 PowerPAD version is available.
The single version (OPA357), comes in the miniature SOT23-6 and SO-8 PowerPAD packages
