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.

NOTES: (1) Integrator Constants are determined by the external components shown in the block diagram. (2) FSR means Full Scale Range, digital output code is from
90000H to 70000H, FSR = 5.0V. (3) Use 20-bit DAC, 20kHz LPF, 400Hz HPF, average response. (4) Average response using a 20-bit reconstruction DAC with 20kHz
low-pass filter and 400Hz high-pass filter.
