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.
