The SD24_A is a powerful 24-bit sigma-delta converter that supports analog to digital conversions. It is based on a 2nd order sigma-delta architecture, supporting up to 1.1 MHz modulation frequency. In addition, it supports a flexible clock divider for the modulation clock, programmable OSR of up to 1024 and an integrated programmable gain amplifier (PGA) of up to 32. The SD24_A  also supports integrated voltage and temperature sensors to perform AVCC and temperature measurements. There is an option to choose an external reference or to use the internal voltage reference of 1.2 V for all analog conversions.
