OP27EPZ

产品概述

The OP27EPZ is a Low Noise Operational Amplifier ideal for precision instrumentation applications. It combines the low offset and drift of the OP07 with both high speed and low noise. A gain bandwidth product of 8MHz and a 2.8V/µs slew rate provide excellent dynamic accuracy in high speed, data-acquisition systems. A low input bias current of ±10nA is achieved by use of a bias current cancellation circuit. Over the military temperature range, this circuit typically holds IB and IOS to ±20nA and 15nA, respectively. The output stage has good load driving capability. A guaranteed swing of ±10V into 600R and low output distortion make it an excellent choice for professional audio applications. These characteristics, coupled with long-term drift of 0.2µV/month, allow the circuit designer to achieve performance levels previously attained only by discrete designs. High volume production of OP27 is achieved by using an on-chip Zener zap-trimming network.
