... The VCA provides two opposing-polarity, volt- age-sensitive control ports. Dynamic range ex- ceeds 115 dB, and THD is typically 0.003 gain. In the 4301A, the VCA is selected for low THD at extremely high levels. The RMS de- tector provides accurate rms-to-dc conversion over dynamic range for signals with ...

... SYM are ating temperature of the 4301 compared to that of the 2150 Series. 4) The input stage of the 4301 VCA uses inte- and SYM. C+ grated P-channel FETs rather than a bias-current corrected bipolar differential amplifier. Input bias currents have therefore been reduced. The RMS Detector — ...

Therefore, to get the most out of the 4301 useful to know the major differences among these opamps being internally connected to the output of 3 the VCA, is intended for current-to-voltage conver- sion. Its input noise performance ...

... AN100, Basic Compressor Limiter Design. The designs in AN100 are based on THAT Corporation’s 2150-Series VCAs and 2252 RMS Detector, but are readily adaptable to the 4301 with only minor modifications. In fact, the circuit presented here is functionally identical to the hard-knee circuit published in AN100. ...

... The RMS detector’s input is similar to that of the VCA. An input resistor ( kW) converts the ac in- 6 put voltage to a current within the linear range of the 4301. (Peak detector input currents should be kept under 1 mA for best linearity.) The coupling capacitor , 47 mf) is recommended to block dc current from (C 3 preceeding stages (and from offset voltage at the in- put of the detector) ...

... VCA, causing modulation of the signal. By itself, the 4301 VCA pro- duces very little noise modulation, and its perfor- mance can be significantly degraded by the use of noisy components in the control voltage path. ...
