DESCRIPTION
The THS4271 and THS4275 are low-noise, 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 THS4275 offers the same performance as the
THS4271 with the addition of power down capability. The
combination of low-noise, high slew rate, wide bandwidth,
low distortion, and unity gain stability make the THS4271
and THS4275 high performance devices across multiple
ac specifications.
Designers using the THS4271 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.
