Overview
The THS3095DDAR is a high-voltage, low-distortion, current-feedback operational amplifier manufactured by Texas Instruments. It is designed to operate within a wide supply voltage range of ±5V to ±16V, making it suitable for applications requiring large linear output signals. The THS3095DDAR features a shutdown pin (PD) that allows the amplifier to enter a low-power standby mode, reducing the quiescent current from 9.5mA to 500µA. This model is particularly well-suited for high-voltage arbitrary waveform generation, pin drivers, and power FET drivers due to its ability to handle large voltage swings and drive low-resistance and high-capacitance loads while maintaining excellent settling time performance. The THS3095DDAR is available in an 8-pin SOIC (DDA) package with PowerPAD™, ensuring efficient thermal management.
