DESCRIPTION
The PCM1760 and DF1760 combine for a low-cost,
high-performance dual 20-bit, 48kHz sampling ana-
log-to-digital conversion system which is specifically
designed for dynamic applications.
The PCM1760/DF1760 pair form a 4-bit, 4th order,
64X oversampling analog-to-digital converter.
The PCM1760 is a delta-sigma modulator that uses a
4-bit quantizer within the modulation loop to achieve
very high dynamic range.
The DF1760 is a high-performance decimating digital
filter. The DF1760 accepts 4-bit 64fs data from the
PCM1760 and decimates to 20-bit 1fs data.
The FIR filter of the DF1760 has pass-band ripple of
less than
±
0.001dB and greater than 100dB of the
reject band attenuation.
