Texas Instruments THS3112 Dual, Low-Noise, High Output Current, 110-MHz Amplifier THS3112CDRG4

The THS3112CDRG4 is a low-noise, high-speed current feedback amplifier designed for applications requiring high performance. It features a wide supply voltage range from ¬±5 V to ¬±15 V and can deliver a high output current of 150 mA minimum. The amplifier has a bandwidth of 110 MHz at a gain of 1 and a slew rate of 1550 V/¬µs at a gain of 2, making it suitable for fast signal processing tasks. Noise performance is a key attribute, with non-inverting current noise at 2.9 pA/,àöHz and inverting current noise at 10.8 pA/,àöHz, contributing to improved signal-to-noise ratios. The device also exhibits low total harmonic distortion of ,Äì78 dBc at 1 MHz while driving a 2 V peak-to-peak output into a 100 Oc load. The THS3112CDRG4 is available in standard SOIC and PowerPAD packages, facilitating thermal management and integration into various circuit designs. It is suitable for applications in communication equipment, video distribution, motor drivers, and piezo drivers, making it a versatile choice for engineers seeking reliable performance in demanding environments.
