ADC16071中文资料16-Bit Delta-Sigma 192 ks/s Analog-to-Digital Converters数据手册TI规格书

描述 Description

General Description
The ADC16071/ADC16471 are 16-bit delta-sigma analog to-digital converters using 64 x 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 t90 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.Key Specifications
