Texas Instruments THS3095
The THS3095 features a power-down pin (PD) that puts the amplifier into a low-power standby mode, and lowers the quiescent current from 9.5 mA to 500 μA. The wide, 32‑V supply range, 6000‑V/µs slewrate, and 310‑mA output current drive make the THS309x an excellent choice for high-voltage arbitrary-waveform-driver applications. The THS309x are offered in an 8‑pin SOIC (DDA) PowerPAD™ integrated circuit package.FEATURES
