- Low EMI: CISPR-11 and CISPR-25 compliant

- Programmable data rate: up to 64kSPS

- Programmable gain: up to 128

- Low drift internal voltage reference

- Internal temperature sensor

- 4-wire SPI interface with cyclic redundancy check (CRC) function

- Safety-related approvals:

- 7070VPEAK enhanced isolation according to DIN EN IEC 60747-17 (VDE 0884-17)

- UL1577-compliant up to 1-minute 5000VRMS isolation

- Package: 20-pin wide-body SOIC

- Operating temperature range: -40°C to +125°C

Applications

- Electricity meters: commercial and residential

- Circuit breakers

- Electric vehicle charging stations

- Battery management systems
