SemiconductorThe UMD9NFHATR with Bipolar Transistors Pre-Biased PNP+NPN Digital Transistor (with built-in resistors) from ROHM Semiconductor is an ultra-compact package integrating two integrated transistors. This device is suitable for various applications such as pre-amplifier differential amplification circuits and high frequency oscillator. This two-transistor device is designed to deliver improved power efficiency, longer battery life, high input impedance, low output impedance, excellent tracking throughout temperature variations, and low current consumption. Additionally, the pre-biasing of the two transistors offers further improved current efficiency by reducing the forward voltage drop, while reducing power dissipation. As well as providing excellent thermal and mechanical stability, this two-transistor device is also designed to be extremely reliable, long-term operation.
