15 The AD717x family offer a complete integrated Sigma-Delta ADC solution which
18 (Factory Automation PLC Input modules). The Sigma-Delta ADC is intended
23 The AD411X family encompasses a series of low power, low noise, 24-bit,
24 sigma-delta analog-to-digital converters that offer a versatile range of
26 fully differential/single-ended and bipolar voltage inputs.
