High Performance
– 150 MHz, –3 dB Bandwidth (VCC = ±15 V)
– 51 V/µs Slew Rate
– –100 dB Third Harmonic Distortion at
250 kHz
Low Noise
– 1.3 nV/√Hz Input-Referred Noise
Differential-Input/Differential-Output
– Balanced Outputs Reject Common-Mode
Noise
– Reduced Second-Harmonic Distortion Due
to Differential Output
Wide Power-Supply Range
– VCC = 5 V Single Supply to ±15 V Dual
Supply
ICC(SD) = 860 µA in Shutdown Mode (THS4130)
The THS413x is made of a true fully-differential signal
path from input to output. This design leads to an
excellent common-mode noise rejection and
improved total harmonic distortion.
