DESCRIPTION
The THS4211 and THS4215 are high slew rate,
unity-gain stable, voltage feedback amplifiers
designed to run from supply voltages as low as 5 V
and as high as 15 V. The THS4215 offers the same
performance as the THS4211 with the addition of
power-down capability. The combination of high slew
rate, wide bandwidth, low distortion, and unity-gain
stability make the THS4211 and THS4215
high-performance devices across multiple ac
specifications.
Designers using the THS4211 are rewarded with
higher dynamic range over a wider frequency band
without the stability concerns of decompensated
amplifiers. These devices are available in SOIC,
MSOP with PowerPAD™, and leadless MSOP with
PowerPAD packages.
