16-Bit Delta-Sigma 192 ks/s Analog-to-Digital Converters

ADC16071 ADC16471 16-Bit Delta-Sigma 192 ks s Analog-to-Digital Converters February 1995 ADC16071 ADC16471 16-Bit Delta-Sigma 192 ks s Analog-to-Digital Converters General Description The ADC16071 ADC16471 are 16-bit delta-sigma analogto-digital converters using 64 c oversampling at 12 288 MHz A 5th-order comb filter and a 246 tap FIR decimation filter are used to achieve an output data rate of up to 192 kHz The combination of oversampling and internal digital filtering greatly reduces the external anti-alias filter requirements to a simple RC low pass filter The FIR filters offer linear phase response 0 005 dB passband ripple and t 90 dB stopband rejection The ADC16071 ADC16471’s analog fourth-order modulator uses switched capacitor technology A built-in fully-differential bandgap voltage reference 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 process for a low power consumption of 500 mW (max) while operating from a single 5V supply A power-down mode reduces 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 requires a minimal external anti-aliasing filter reference or interface logic The ADC16071 ADC16471’s serial interface is compatible with the DSP56001 TMS32.
