ADC-based: digitally-isolated: wide-input: 16-channel: AC/DC binary input reference design
Description
This reference design showcases a cost-optimized and scalable ADC-based AC/DC binary input module (BIM) architecture with reinforced isolation. The 16 channels of a 10- or 12-bit SAR ADC are used for sensing multiple binary inputs. The op amps: in addition to keeping the cost per-channel low: provide optimal signal conditioning for each input. A digital isolator (basic or reinforced) is used to isolate the host MCU or processor. A provision is available to measure temperature: humidity: and magnetic field for diagnostics. A reinforced isolation DC/DC power supply with configurable output provides the required supply for the binary module.
Features
- Scalable input AC/DC binary input module with ADC front endIsolated DC/DC based power supply to isolate the host from the sensor sideImproved system reliability from use of digital isolators over optocoupler-based solutionWide input range from 10 V to 300 V and supports measurement in AC or DC input voltagesMeasurement of input voltage provides provision for programmable thresholdDevice selection optimized per channel
Applications
