The TT1340 is a monolithic array containing two matched NPN and two matched PNP transistors, designed for low-noise amplifier input stages, current mirrors, and log/antilog amplifiers. It is fabricated in a dielectrically isolated complementary bipolar process, providing low crosstalk and high DC isolation. The NPN transistors exhibit a voltage noise density of 0.8 nV/√Hz and a gain-bandwidth product of 350 MHz, while the PNP transistors show 0.75 nV/√Hz noise and a 325 MHz gain-bandwidth product. Transistor matching within the same gender is typical to ±5% for current gain and ±0.5 mV for base-emitter voltage at 1 mA collector current. The device supports a maximum collector-emitter voltage of 36 V and operates from 0°C to 70°C. It is housed in an LCC package, with pinout configurations defined for the series. ESD sensitivity requires proper handling precautions.
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.
