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

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
