THS4271-EP - Enhanced Product Low Noise High Slew Rate Unity Gain Stable Voltage Feedback Amplifier

Updated : 2020-01-09 14:17:47
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.
