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.
