Multi-Bit Enhanced Noise Shaping 20-Bit  
ANALOG-TO-DIGITAL CONVERSION SYSTEM  
FEATURES  
DESCRIPTION  
DUAL 20-BIT MONOLITHIC MODULATOR  
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.  
(PCM1760) AND MONOLITHIC  
DECIMATING DIGITAL FILTER (DF1760)  
HIGH PERFORMANCE:  
THD+N: –92dB typ, –90dB max  
Dynamic Range: 108dB typ  
The PCM1760/DF1760 pair form a 4-bit, 4th order,  
64X oversampling analog-to-digital converter.  
SNR: 108dB min, 110dB typ  
Channel Separation: 98dB typ, 94dB min  
The PCM1760 is a delta-sigma modulator that uses a  
4-bit quantizer within the modulation loop to achieve  
very high dynamic range.  
64X OVERSAMPLING  
CO-PHASE CONVERSION  
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.  
RUNS ON 256fs OR 384fs SYSTEM  
CLOCK  
VERSATILE INTERFACE CAPABILITY:  
16-, 20-Bit Output  
The FIR filter of the DF1760 has pass-band ripple of  
less than ±0.001dB and greater than 100dB of the  
reject band attenuation.  
MSB First or LSB First Format  
OPTIONAL FUNCTIONS:  
Offset Error Calibration  
Overflow Detection  
Power Down Mode (DF1760)  
RUNS ON ±5V SUPPLIES (PCM1760) AND  
5V SUPPLY (DF1760)
