The TT1340F is a monolithic matched transistor array containing two NPN and two PNP transistors, designed for low-noise amplifier input stages, current mirrors, and log/antilog amplifiers. It is available in a ceramic LCC package with a dielectrically isolated structure to minimize crosstalk and maximize DC isolation. The NPN transistors exhibit a typical gain-bandwidth product of 350 MHz and noise density of 0.8 nV/√Hz, while the PNP transistors show 325 MHz and 0.75 nV/√Hz. Current gain matching within the same transistor type is typically 5%. Maximum collector-emitter voltage is 36 V for both NPN and PNP devices. Operating temperature range is 0 to 70°C. The device is ESD-sensitive and not intended for life support applications.
The TT Semiconductor 1300 series are large-geometry, 4-transistor, monolithic NPN and/or PNP arrays exhibiting both high speed and low noise, with excellent parameter matching between transistors of the same gender. With typical base-spreading resistances of 25 ohms for the PNP devices (30 ohms for the NPNs), their low voltage noise of under 1 nV/Hz½, the 1300 series are ideally suited for low-noise amplifier input stages, among other applications.
