description
The TLO11, TLO12, TLO14A, and TLO21 are Wilson current mirrors with output currents in fixed proportion to the input currents and substantially independent of changes in voltage, load, and temperature. These devices make use of the tight matching properties of identical bipolar transistors on a monolithic integrated circuit chip to achieve current-ratio accuracy typically better than 98%. Current mirrors are used extensively in linear integrated circuit designs as active loads for operational- amplifier stages and as current sources for other stages. The TLO11 family gives the designer this same capability with no sacrifice in accuracy or stability. The TLO11, TLO12, and TLO14A are designed to operate with input currents up to 1 mA and output voltage up to 35 V. The TLO21 is designed for 2 mA and 35 V. schematics T1011 T1012 TLO148 T1021 ‘our our our out | ive. te a !

Input and output voltages are with respect to the common terminal. Neither voltage should be more negative than -0.3 V. 2. For operation above 25°C free-air temperature, derate linearly at the rate of 6.2 mW/°C. The LP package dissipation rating was based on thermal resistance, Raja, measured in still air with the device mounted in an Augat socket. The bottom of the package was 10 mm (0.375 in.) above the socket. recommended operating conditions Fr a [ain wa Max] ON [Ouputvotage, Vo BB Input current, | [ tioz, 0.0022 0.002 | preven fo [Aiothers 0.001 foo01 [Operating tees temperature TaSSSSCid 4] | SS UE, Texas INSTRUMENTS 4-50 POST OFFICE BOX 655303 « DALLAS, TEXAS 75265
