DESCRIPTION
The THS3110 and THS3111 are low-noise,
high-voltage, current-feedback amplifiers designed to
operate over a wide supply range of
鹵5
V to
鹵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 碌A(chǔ).
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 high
1300-V/碌s slew rate, the THS3110 and THS3111
amplifiers allow for high output voltage swings at high
frequencies.
The THS3110 and THS3111 are offered in a 8-pin
SOIC (D), and the 8-pin MSOP (DGN) packages with
