The TT1320 is a monolithic array of four matched PNP transistors designed for low-noise amplifier input stages, current sources, and current mirrors. It features a typical noise voltage density of 0.75 nV/√Hz, a gain-bandwidth product of 325 MHz, and base-spreading resistance of 25 ohms. Transistor matching is within 5% at 1 mA collector current. The device operates over a temperature range of 0°C to 70°C and has a collector-emitter voltage rating of -36 V. It is available in ceramic flatpack and LCC packages. The part meets no stated industry standards beyond its operational specifications. All variants in the TT1300 series share identical core electrical specifications; the TT1320S is a variant of the TT1320 with an unspecified trailing code.
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.
