Unity Gain Stability
Low Voltage Noise
The THS4271 and THS4275 are low-noise, high slew
rate, unity gain stable voltage-feedback amplifiers
–
3 nV/
√Hz
designed to run from supply voltages as low as 5 V
High Slew Rate: 1000 V/
μs
and as high as ±5 V. The THS4275 offers the same
Low Distortion
performance as the THS4271 with the addition of a
power-down capability. The combination of low-noise,
–
–92 dBc THD at 30 MHz
high slew rate, wide bandwidth, low distortion, and
Wide Bandwidth: 1.4 GHz
unity gain stability make the THS4271 and THS4275

Power Down Functionality (THS4275)
Designers using the THS4271 are rewarded with
higher dynamic range over a wider frequency band
Evaluation Module Available
without the stability concerns of decompensated
amplifiers. The devices are available in SOIC, MSOP
APPLICATIONS

with
High Linearity ADC Preamplifier
PowerPAD packages.
Wireless Communication Receivers
The THS4271 and THS4275 may have low-level
Differential to Single-Ended Conversion
oscillation when the die temperature (also known as
DAC Output Buffer
the junction temperature) exceeds +60°C. For more
