OP27中文资料低噪声高速精确运算放大器数据手册TI规格书

描述 Description

The OP27 operational amplifiers combine outstanding noise performance with excellent precision and high-speed specifications. The wideband noise is only 3 nV/Hz and with the 1/f noise corner at 2.7 Hz, low noise is maintained for all low-frequency applications.

The outstanding characteristics of the OP27 make these devices excellent choices for low-noise amplifier applications requiring precision performance and reliability.

The OP27 series is compensated for unity gain. The OP27A and OP27C are characterized for operation over the full military temperature range of –55°C to 125°C.
