FEATURES  
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.

Unity Gain Bandwidth: 300 MHz  
0.1-dB Bandwidth: 120 MHz (G = 2)  
High Slew Rate: 7000 V/μs  
HD3 at 10 MHz: –81 dBc (G = 2, RL = 150 )  
High Output Current: ±145 mA into 50 Ω  
Power-Supply Voltage Range: ±5 V to ±15 V  
APPLICATIONS  
High-Speed Signal Processing  
Test and Measurement Systems  
VDSL Line Driver  
High-Voltage ADC Preamplifier  
Video Line Driver  
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.  
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.
