GENERAL DESCRIPTION
Figure 1. 8-Lead TO-99 (J-Suffix) The OP27 precision operational amplifier combines the low offset and drift of the OP07 with both high speed and low noise.

noise, en = 3.5 nV/√Hz, at 10 Hz, a low 1/f noise corner
V– 4 5 NC
2 0 -0 frequency of 2.7 Hz, and high gain (1.8 million), allow accurate 7 1
NC = NO CONNECT
3 0 0 high-gain amplification of low-level signals. A gain bandwidth product of 8 MHz and a 2.8 V/µs slew rate provide excellent Figure 2. 8-Lead CERDIP – Glass Hermetic Seal (Z-Suffix), 8-Lead PDIP (P-Suffix), and 8-Lead SOIC (S-Suffix) dynamic accuracy in high speed, data-acquisition systems. A low input bias current of ±10 nA is achieved by use of a bias current cancellation circuit. Over the military temperature range, this circuit typical y holds IB and IOS to ±20 nA and 15 nA, respectively. The output stage has good load driving capability. A guaranteed swing of ±10 V into 600 Ω and low output distortion make the OP27 an excellent choice for professional audio applications. (Continued on Page 3)
