OP27G OP-AMP: Application, Pinout and Datasheet

OP27G is a precision operational amplifier. It combines the low offset and drift of OP07 have high speed and low noise at the same time. An offset as low as 25 µV and a maximum drift of 0.6 µV/°C make OP27G is very suitable for precision instrument applications. Low Noise, en = 3.5 nV/√Hz, at 10 Hz, low 1/f noise angle 2.7 Hz frequency and high gain (1.8 million), allowing accurate high-gain amplification of low-level signals. Gain bandwidth The product of 8 MHz and 2.8 V/µs slew rate provides excellent dynamic accuracy in high-speed data acquisition systems. Low input bias current of ±10 nA is achieved by using bias Current elimination circuit. Exceeding military temperature range, the circuit usually keeps IB and IOS at ±20 nA and 15 nA, respectively. The output stage has good load driving capability. A guarantee ±10 V to 600 Ω swing and low output distortion OP27G is an excellent choice for professional audio applications.

       PSRR and CMRR exceed 120 dB. These characteristics, coupled The long-term drift is 0.2 µV/month, allowing circuit designers achieve a level of performance previously only available through discrete design. The low-cost and mass production of OP27G is achieved in the following ways use the on-chip Zener zap to trim the network. This is reliable and the stable offset trimming scheme has proven its effectiveness years of production history. OP27G provides excellent performance in low noise, high-precision amplification of low-level signals. Application Including stable integrator, precision adding amplifier, precision voltage threshold detector, comparator and Professional audio circuits, such as tape heads and microphones Preamplifier.
