ADC16071/ADC16471  
16-Bit Delta-Sigma 192 ks/s Analog-to-Digital Converters  
General Description  
The ADC16071/ADC16471 are 16-bit delta-sigma analog-

12.288 MHz. A 5th-order comb filter and a 246 tap FIR deci-  
mation filter are used to achieve an output data rate of up to  
192 kHz. The combination of oversampling and internal digi-  
tal filtering greatly reduces the external anti-alias filter re-  
quirements to a simple RC low pass filter. The FIR filters  
offer linear phase response, 0.005 dB passband ripple, and

90 dB stopband rejection. The ADC16071/ADC16471’s  
analog fourth-order modulator uses switched capacitor  
technology. A built-in fully-differential bandgap voltage ref-  
erence is also included in the ADC16471. The ADC16071  
has no internal reference and requires externally applied  
reference voltages.

The ADC16071/ADC16471 use an advanced BiCMOS pro-  
cess for a low power consumption of 500 mW (max) while  
operating from a single 5V supply. A power-down mode re-  
duces the power supply current from 100 mA (max) in the  
active mode to 1.3 mA (max).

The ADC16071/ADC16471 are ideal analog-to-digital front  
ends for signal processing applications. They provide a  
complete high resolution signal acquisition system that re-  
quires a minimal external anti-aliasing filter, reference, or  
interface logic.
