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. Fabricated in a dielectrically isolated complementary bipolar process, it exhibits low voltage noise of 0.8 nV/√Hz for NPNs and 0.75 nV/√Hz for PNPs, with a gain-bandwidth product of 350 MHz for NPNs and 325 MHz for PNPs. Transistor matching within the same gender is typical to 5% in current gain. The device operates over a temperature range of 0°C to 70°C and has a collector-emitter voltage rating of 36 V. The transistors are electrically isolated by oxide layers, enabling low crosstalk and high DC isolation. The package is an LCC, with pinout configurations defined for the TT1340 variant.
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.
