Product data sheet
10.6 FIR filters
The DAC1005D650 integrates three selectable Finite Impulse Response (FIR) filters
which enable the device to use interpolation rates of 2 , 4 or 8 .
All three interpolation filters have a stop-band attenuation of at least 80 dBc and a
pass-band ripple of less than 0.0005 dB.
The coefficients of the interpolation filters are given in
coefficients”.
