THS3061 - High-Voltage, High Slew-Rate Current Feedback Amplifier

Updated : 2020-01-09 14:18:02
Description

The THS3061 (single) and THS3062 (dual) are high-voltage, high slew-rate current feedback amplifiers utilizing Texas Instruments' BICOM-1 process. Designed for low-distortion with a high slew rate of 7000 V/µs, the THS306x amplifiers are ideally suited for applications requiring large, linear output signals such as video line drivers and VDSL line drivers.

The THS3061 and THS3062 provide well-regulated ac performance characteristics with power supplies ranging from ±5-V operation up to ±15-V supplies. Most notably, the 0.1-dB flat bandwidth is exceedingly high, reaching beyond 100 MHz, and the THS306x has less than 0.3 dB of peaking in the frequency response when configured in unity gain. The unity-gain bandwidth of 300 MHz provides excellent distortion characteristics at 10 MHz. The flexibility of the current-feedback design allows a 220-MHz, –3-dB bandwidth in a gain of 10, indicating excellent performance even at high gains.

The THS306x consumes 8.3 mA per-channel quiescent current at room temperature, and has the capability of producing up to ±145 mA of output current. The THS3061 is packaged in an 8-pin SOIC and an 8-pin MSOP with PowerPAD. The THS3062 is available in an 8-pin SOIC with PowerPAD and an 8-pin MSP with PowerPAD.
