Each of these JFET-input operational amplifiers incorporates well- matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit. The devices feature high slew rates, low input bias and offset currents, and low offset voltage temperature coefficient. Offset adjustment and external compensation options are available within the TLO8_ family. Device types with an M suffix are characterized for operation over the full military temperature range of 55C to 125C, those with an I suffix are characterized for operation from 40C to 85C, and those with a C suffix are characterized for operation from OC to 70C.

Differential voltages are at the noninverting input terminal with respect to the inverting input terminal. 3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less. 4. The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not exceeded. 2-406 TEXAS % INSTRUMENTS POST OFFICE BOX 655012 DALLAS, TEXAS 75265TLO8O THRU TLO85, TLO80A THRU TLO84A TLO81B, TLO82B, TLO84B JFET-INPUT OPERATIONAL AMPLIFIERS DISSIPATION RATING TABLE PACKAGE Ta = 25C DERATING DERATE Ta = 70C Ta = 85C Ta = 125C POWER RATING FACTOR ABOVE Ta POWER RATING POWER RATING POWER RATING D (8 Pin) 680 mw 5.8 mw/C 32C 464 mw 377 mw N/A D (14 Pin) 680 mw 7.6 mW/C 60C 608 mw 494 mw N/A FK 680 mw 11.0 mw/ec 88C 680 mW 680 mW 275 mw J (TLO&8_M) 680 mw 11.0 mw/c 88C 680 mW 680 mW 275 mW J (all others} 680 mW 8.2 mW/C 67C 656 mW 533 mw N/A JG (TLOB_M) 680 mw 8.4 mW/C 69C 672 mw 546 mW 210 mW JG (all others) 680 mw 6.6 mW/C 47C 528 mw 429 mw N/A N 680 mW 9.2 mW/C 76C 680 mw 598 mW N/A P 680 mW 8.0 mWw/C 65C 640 mw 520 mW N/A VW electrical characteristics, Vcc + = +15 V (unless otherwise noted) n i TLOSOM, TLOS1M TLOS4M _ PARAMETER TEST CONDITIONS TLO&2M, TLO83M UNIT = MIN TYP MAX MIN TYP MAX Ce Vo = 9, Ta = 25C 3 6 3 9 Vio Input offset voltage A mV E Rg = 500 Ta = 55C to 125C 9 15 <q Temperature ; Vo = 0, Rg = 502, 7s avio coefficient of input 18 18 av/c Ta = 55C to 125C c offset voltage 3 Ta = 25C 5 100 5 100 A ~~ lo input offset current?
