The TT1340D 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 features a base-spreading resistance of 25 ohms for PNP and 30 ohms for NPN devices, with voltage noise density of 0.75 nV/√Hz for PNP and 0.8 nV/√Hz for NPN. The transistors exhibit a gain-bandwidth product of 350 MHz for NPN and 325 MHz for PNP, with current gain matching within 5% at 1 mA collector current. The device is fabricated in a dielectrically isolated complementary bipolar process, enabling low crosstalk and high DC isolation. Maximum collector-emitter voltage is 36 V, and operating temperature ranges from 0°C to 70°C. The part is available in ceramic flatpack and LCC packages. It is rated as ESD-sensitive and has not been designed 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.
