Most notably, the 0.1-dB • Power-Down Feature: (THS3120 Only) flat bandwidth is exceedingly high, reaching beyond 90 MHz. The unity gain bandwidth of 130 MHz allows for good distortion characteristics at 10 MHz. Coupled • Video Distribution with high 1700-V/µs slew rate, the THS3120 and • Power FET Driver THS3121 amplifiers allow for high output voltage swings at high frequencies. • Pin Driver • Capacitive Load Driver The THS3120 and THS3121 are offered in a 8-pin SOIC (D), and the 8-pin MSOP (DGN) packages with PowerPAD™.
