Unity-Gain Stability
Wide Bandwidth: 1 GHz
The THS4211 and THS4215 are high slew rate,
unity-gain
stable,
voltage
feedback
amplifiers
High Slew Rate: 970 V/s
designed to run from supply voltages as low as 5 V
Low Distortion:
and as high as 15 V. The THS4215 offers the same
–
–90 dBc THD at 30 MHz
performance as the THS4211 with the addition of
power-down capability. The combination of high slew
