IC40 D.A.C
Digital to
Analogue Converter (DAC)
The
new Rega IC40 is a high performance 24 bit
Digital to
Analogue Converter. It employs a novel 64
level sigma delta D.A.C design which provides optimised
signal-to-noise performance and clock jitter. The Rega IC40 consists
of a three stage linear phase FIR filter followed by a 16x
over-sampled linear interpolator, that significantly reduces high
frequency images when compared to the more usual sample and hold
implementation. With the 64 level sigma delta DAC the magnitude of
errors induced by clock jitter are significantly reduced and this is
further enhanced by switched capacitor implementation of the low
pass filter, which is also insensitive to clock jitter. |
