1 TL8 TL8A - TL8B GENERAL PURPOE INGLE J-FET OPERATIONAL AMPLIFIER. LOW POWER CONUMPTION WIDE COMMON-MODE (UP TO VCC + ) AND DIFFERENTIAL VOLTAGE RANGE. LOW INPUT BIA AND OFFET CURRENT OUTPUT HORT-CIRCUIT PROTECTION HIGH INPUT IMPEDANCE J FET INPUT TAGE. INTERNAL FREQUENCY COMPENATION LATCH UP FREE OPERATION HIGH LEW RATE : 6V/µs (typ) N DIP8 (Plastic Package) D O8 (Plastic Micropackage) DECRIPTION The TL8, TL8A and TL8B are high speed J FET inputsingle operationalamplifiers incorporating well matched, high voltage J FET and bipolar transistors in a monolithic integrated circuit. The devicesfeaturehigh slew rates, low input bias and offset currents, and low offset voltage temperature coefficient.

All voltage values, except differential voltage, are with respect to the zero reference level (ground) of the supply voltages where the zero reference level is the midpoint between + and. 2. Differential voltages are at the non-inverting 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 volts, whichever is less.. 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. o C o C 8-2.TBL 2/9
