MAX71071
Dual-Channel Isolated Metrology ADCs
Eliminate Current Transformers with Isolated ADC
Part Details
- Accurately Measure Voltage and Current
- Dual 24-Bit ADC
- 0.1% Accuracy Over 2000:1 Dynamic Range
- Exceeds IEC 62053/ANSI C12.20 Standards
- On-Chip Temperature Sensor Enables Localized Digital Temperature Compensation

The MAX71071/MAX71071H are dual-channel isolated analog-to-digital converters (ADCs) for use with a compatible MAX71xxx host. The device provides current and voltage measurements to the host while the host provides control, command, and power to the MAX71071/MAX71071H. A pulse transformer provides the isolated data, clock, and power path between the device and host, eliminating the need for additional isolation components in the measurement subsystem. These metrology ADCs operate over the industrial temperature range and come in a 10-pin µMAX® package.
Applications
- Industrial Energy Meters
- Residential Energy Meters
