OP275GS

The OP275GS is the amplifier to feature the Butler Amplifier front-end. This new front-end design connects both bipo lar and JFET transistors, gaining amplifiers with the accuracy and low noise performance of bipolar transistors, and the speed and sound quality of JFETs. Total Harmonic Distortion plus Noise equals that of previous audio amplifiers, but at much lower supply currents.

Features of the OP275GS are:(1)excellent sonic characteristics; (2)low noise: 6 nV/Hz; (3)low distortion: 0.0006%; (4)high slew rate: 22 V/us; (5)wide bandwidth: 9 MHz; (6)low supply current: 5 mA; (7)low offset voltage: 1 mV; (8)low offset current: 2 nA; (9)unity gain stable; (10)SOIC-8 package.

The absolute maximum ratings and electrical characteristics(VS = 615.0 V, TA = +258C) of the OP275GS can be summ arized as:(1):supply voltage is ±22 V;(2):input voltage2 is ±22 V;(3):differential tnput voltage is ±7.5 V;(4):output short-circuit duration to GND3 is indefinite; (5):storage temperature ranges from 65°C to +150°C;(6):operating temperature ranges from 40°C to +85°C;(7):junction temperature ranges (P, S Package)from 65°C to +150°C;(8):lead temperature range (soldering, 60 sec)is +300°C.Electrical characteristics:(1):offset voltage is 1mV max w hen TA is between -40 and 85;(2):large signal voltage gain is 250V/mV when RL is 2K;(3):offset voltage drift is 2uV/;(4):supply voltage range is±4.5V min and ±22V max.
