AD73460 Analog Sigma-Delta Modulator The AD73460 input channels employ a sigma-delta conversion technique, which provides a high resolution 16-bit output with system filtering being implemented on-chip. Sigma-delta converters employ a technique known as over- sampling, where the sampling rate is ...
Page 13
ADC Coding The ADC coding scheme is in two’s complement format (see Figure 5). The output words are formed by the decimation filter, which grows the word length from the single-bit output of the sigma-delta modulator to a 15-bit word, ...

AD73460 The EZ-ICE uses the EE (emulator enable) signal to take control of the AD73460 in the target system. This causes the processor to use its ERESET, EBR, and EBG pins instead of the RESET, BR, and BG pins. The ...
