Isolated Sigma-Delta Modulator
The serial interface is digitally isolated. High speed CMOS, combined with monolithic air core transformer technology, means the on-chip isolation provides outstanding performance characteristics superior to alternatives such as optocoupler devices. The part contains an on-chip reference and has an operating temperature range of −40°C to +125°C. The AD7400A is offered in an 8-lead surface-mount PDIP with gull wing leads and a 16-lead SOIC package.
