DESCRIPTION
The THS4271 is a low-noise, high slew rate, unity
gain stable voltage-feedback amplifier designed to
run from supply voltages as low as 5 V. The
combination of low-noise, high slew rate, wide
bandwidth, low distortion, and unity gain stability
make the THS4271 a high performance device
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.
The THS4271 may have low-level oscillation when
the die temperature (also known as the junction
temperature) exceeds +60°C and is not
recommended for new designs. For more information,
see Maximum Die Temperature to Prevent
Oscillation.
