Typical Application for AMC1204, 20-MHz, Second-Order, Isolated Delta-Sigma Modulator for Resolver-Based Motor Control Analog Front End

Typical Application for AMC1204, 20-MHz, Second-Order, Isolated Delta-Sigma ADC that can be clocked at up to 20 MHz. The digital isolation of the modulator output is provided by a silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference. When used with an appropriate external digital filter, an effective number of bits (ENOB) of 14 is achieved at a data rate of 78 kSPS
