This isolated, 3.65-mm thin reference design enables highly-integrated, bipolar input and high-performance solutions with a 24-bit delta-sigma analog-to-digital converter (ADC). Modern analog input modules need high performance in different aspects such as higher channel density at the same room size, which requires lower power consumption, and a wider operating temperature range at the same time.
