Dual High Frequency Differential Amplifier For Low Power Applications to 500MHz
The CA3102 consists of two independent differential amplifiers with associated constant current transistors on a common monolithic substrate. The six transistors which comprise the amplifiers are general purpose devices which exhibit low 1/f noise and a value fT in excess of 1GHz. These features make the CA3102 useful from to 500MHz. Bias and load resistors have been omitted to provide maximum application flexibility. The monolithic construction of the CA3102 provides close electrical and thermal matching of the amplifiers. This feature makes this device particularly useful in dual channel applications where matched performance of the two channels is required. The CA3102 has a separate substrate connection for greater design flexibility.Features

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES: 1. The collector of each transistor of the CA3102 is isolated from the substrate by an integral diode. The substrate (Terminal 9) must be connected to the most negative point in the external circuit to maintain isolation between transistors and to provide for normal transistor action. JA is measured with the component mounted on an evaluation PC board in free air.
