DESCRIPTION
The THS3110 and THS3111 are low-noise,
high-voltage, current-feedback amplifiers designed to
operate over a wide supply range of ±5 V to ±15 V for
today's high performance applications.
The THS3110 features a power-down pin (PD) that
puts the amplifier in low-power standby mode, and
lowers the quiescent current from 4.8 mA to 270 μA.
These amplifiers provide well-regulated ac
performance characteristics. The unity-gain
bandwidth of 100 MHz allows for good distortion
characteristics below 10 MHz. Coupled with a high
1300-V/μs slew rate, the THS3110 and THS3111
amplifiers allow for high output voltage swings at high
frequencies.
The THS3110 and THS3111 are offered in the
SOIC-8 (D) and the MSOP-8 (DGN) packages with
PowerPAD™.
