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. The devices are available in SOIC, MSOP
with PowerPAD™, and leadless MSOP with
PowerPAD packages.
