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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not implied.
(2) The absolute maximum ratings under any condition is limited by the constraints of the silicon process. Stresses above these ratings may
cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are
stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied.
(3) The maximum junction temperature for continuous operation is limited by package constraints. Operation above this temperature may
result in reduced reliability and/or lifetime of the device.

(1) The THS4211/5 may incorporate a PowerPAD™ on the underside of the chip. This acts as a heat sink and must be connected to a
thermally dissipative plane for proper power dissipation. Failure to do so may result in exceeding the maximum junction temperature
which could permanently damage the device. See TI technical briefs SLMA002 and SLMA004 for more information about utilizing the
PowerPAD thermally enhanced package.
(2) This data was taken using the JEDEC standard High-K test PCB.
(3) Power rating is determined with a junction temperature of +125°C. This is the point where distortion starts to substantially increase.
Thermal management of the final PCB should strive to keep the junction temperature at or below +125°C for best performance and long
term reliability.
