DGN-8 DGK-8 D-8 DRB-8 THS4271 THS4275 www.ti.com SLOS397F – JULY 2002 – REVISED OCTOBER 2009 LOW NOISE, HIGH SLEW RATE, UNITY GAIN STABLE VOLTAGE FEEDBACK AMPLIFIER Check for Samples: THS4271 THS4275 FEATURES 1 23 Unity Gain Stability Low Voltage Noise – 3 nV/√Hz High Slew Rate: 1000 V/μs Low Distortion – –92 dBc THD at 30 MHz Wide Bandwidth: 1.4 GHz Supply Voltages – +5 V, ±5 V Power Down Functionality (THS4275) Evaluation Module Available APPLICATIONS High Linearity ADC Preamplifier Wireless Communication Receivers Differential to Single-Ended Conversion DAC Output Buffer Active Filtering Low-Noise, Low-Distortion, Wideband Application Circuit 50 Ω Source +5 V 50 Ω + VI 49.9 Ω THS4271 VO _ 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 ±5 V. The THS4275 offers the same performance as the THS4271 with the addition of a 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. The THS4271 and THS4275 may...
