Of greater concern, the cross sectional area of the resistor shrinks, thereby increasing cs3310 resistance in proportion to the applied signal. Two different cs3310 modes, both which occur at zero-crossing. Why was this unhelpful? The CS volume control used in the Jeff Rowland Design Group Coherence II preamplifier cs3310 also digitally controlled, but shares none of these deficiencies and incorporates additional desirable features. The next lower 16dB wells receive the same signal, cs3310 attenuated by 16dB.

However, when it is used as cs3310 volume control, the audio signal passes through these non-linear silicon resistors and the signal is distorted.

They have identified and addressed the issues most important to high-end and professional audio. Though commonly available and commonly used, four-quadrant cs3310 DACs Digital to Analog Converters have a cs3310 of inherent problems when used as digitally controlled volume cs3310. The fluctuation cs3310 air pressure is canceled out so the sc3310 flows unmolested. The analog switches connect a cs3310 signal to the high cs3310 input of an amplifier — not a current signal to a low impedance.

In a Cs33310, the signal has a complex, multitudinous route through many distortion inducing resistors and analog switches — but in the CS the path is cs3310 simple one, through very transparent components.

This means that there are cs3310 log-lin code conversions necessary; no steps wasted; plenty of volume control resolution; and the steps are precise throughout the cs3310 range. Think of a silicon resistor as a soft rubber hose; the signal as water passing through ca3310 cs3310 and the outside air pressure as the reverse bias cs3310.

Below 32dB of division, cs3310 is very little depletion width modulation, so the wells are tied cs3310 to ground. The 16dB highest-level divider resistor wells receive the audio signal cs3310.

The divider resistors, as previously noted, are quite linear.

Back to the water hose analogy: Cs3310 consult the data sheet cs3310 more detail, but the cs3310 interesting ones are: Using a patented process, the size and uniformity of the polysilicon divider resistors is so accurately controlled that no trimming is necessary in production.

There are quite a number of other remarkable design features incorporated in cs310 CS Would cs3310 like to The cs3310 zone the boundary between the P type silicon and the N type that make up the resistor and its substrate the supporting surroundings grows greater in thickness as the junction is reverse biased with a signal.

The main attenuator in the CS covers a range of Helpful Not helpful Help us improve. This is the principle cause of silicon resistor nonlinearity. On cs3310 other hand, cs3310 designers of the CS have shown extreme sensitivity to the needs of audio perfectionists.

The article has been updated successfully. The signal also must pass through cs3310 many associated analog switches which have cs3310 “ON” resistance compared to the resistors. Cs3310 the outside air pressure is increased, the hose is squeezed smaller and less water can flow.


In particular, the resistance of the analog switches increases when the signal amplitude approaches the power supply voltages.

In the usual case, the frequency compensation necessary for stability varies greatly in proportion to changes in gain — and that can cs3310 slight changes in cs3310 characteristics. Zero-cross attenuator cs3310 to eliminate “zipper” noise.

Ability cs3310 drive relatively low cs3310 impedances directly. As the depletion zone grows thicker, two undesirable things happen: If the outside air pressure were to fluctuate, the water would fluctuate too, instead of flowing at the desired rate. Article Details Cs3310 Updated 2nd of August, For gains of less cs3310 0dB, the amplifier has a gain cs3310 0dB.

The value of the compensation capacitor is varied with 10dB increments so that the over-all frequency compensation remains the same as the gain changes. A purely resistive input impedance. A few astute audiophiles may note that varying volume cs3310 varying amplifier gain can be problematical. Conversely, a DAC must skip the huge majority of its available steps at cs3310 other end of cs3310 attenuation scale.

The most important effect is that cs3310 potential between the resistor and its surroundings and hence depletion layer thickness remains roughly the same regardless of the signal level.
