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 notable,
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 allows for
excellent distortion characteristics at 10 MHz. The
flexibility of the current feedback design allows for 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.
