•
Low Noise
The
THS3110
and
THS3111
are
low-noise,
high-voltage, current-feedback amplifiers designed to
–
2-pA/
√
Hz Noninverting Current Noise
operate over a wide supply range of ±5 V to ±15 V for
–
10-pA/
√
Hz Inverting Current Noise
today's high performance applications.
–
3-nV/
√
Hz Voltage Noise
The THS3110 features a power-down pin (PD) that
•
High Output Current Drive: 260 mA
puts the amplifier in low-power standby mode, and
•
High Slew Rate: 1300 V/
μ
s
lowers the quiescent current from 4.8 mA to 270
μ
