Dual Independent Differential Amp for Low Power Applications from to 120MHz
The CA3054 consists of two independent differential amplifiers with associated constant current transistors on a common monolithic substrate. The six NPN transistors which comprise the amplifiers are general purpose devices which exhibit low 1/f noise and a value fT in excess of 300MHz. These feature make the CA3054 useful from to 120MHz. Bias and load resistors have been omitted to provide maximum application flexibility. The monolithic construction of the CA3054 provides close electrical and thermal matching of the amplifiers. This feature makes these devices particularly useful in dual channel applications where matched performance of the two channels is required.Features

NOTES: 1. The collector of each transistor of the CA3054 is isolated from the substrate by an integral diode. The substrate must be connected to a voltage which is more negative than any collector voltage in order to maintain isolation between transistors and provide for normal transistor action. The substrate should be maintained at signal (AC) ground by means of a suitable grounding capacitor, to avoid undesired coupling between transistors. JA is measured with the component mounted on an evaluation PC board in free air.
The following chart gives the range of voltages which can be applied to the terminals listed vertically with respect to the terminals listed horizontally. For example, the voltage range of the vertical Terminal 2 with respect to Terminal to -5V. (NOTE 4) TERM NO.
NOTES: 3. Voltages are not normally applied between these terminals. Voltages appearing between these terminals will be safe if the specified limits between all other terminals are not exceeded. 4. Terminal No. CA3054 is not used.
