MAX71071+T - Dual 24-Bit Isolated ADC | Analog Devices
Артикул: MAX71071+T ✓ АктивенMAX71071+T Обзор
An isolated ADC is an analog-to-digital converter whose measurement side is electrically separated from the control and processing side. This isolation limits the transfer of unwanted voltage and current between a high-voltage or high-current measurement environment and the host electronics. Within the signal-chain hierarchy, the MAX71071+T is a data-acquisition IC, an isolated ADC, and ultimately a metrology measurement component.
The MAX71071+T provides two measurement inputs, 24-bit resolution, and simultaneous isolation through a pulse transformer. The pulse transformer carries the isolated data, clock, and power path, reducing the need for separate isolation components in the measurement subsystem. The host retains responsibility for control commands and the associated power supplied toward the measurement interface.
This architecture is intended to measure current and voltage while maintaining an isolation barrier between the sensed quantities and the host. The exact input ranges, accuracy figures, sampling rate, power requirements, channel multiplexing arrangement, and timing characteristics should be confirmed against the relevant MAX71071 manufacturer documentation before setting the analog front end and system timing.
Typical uses include isolated current monitoring, isolated voltage measurement, industrial metering equipment, power-system instrumentation, and other metrology systems that pair the converter with a compatible MAX71xxx host. The isolated interface is particularly useful when the measured circuit and the controller must remain galvanically separated.
Designers should begin with the host-interface requirements, supported input ranges, and isolation ratings. Transformer-based isolation imposes timing and layout considerations around the measurement side, while host-side routing must preserve clock and data signal integrity. Component values, filtering, grounding, and creepage requirements should be derived from the application voltage, current, bandwidth, and safety environment.
This product page combines the manufacturer product information, distributor listings, family relationships, and practical selection guidance to clarify where the MAX71071+T belongs in an isolated metrology design. It also distinguishes documented functions from parameters that require engineering confirmation before layout release.

Типичное применение
MAX71071+T подходит для 6 применениеs: Isolated Current Monitoring, Isolated Voltage Measurement, Power-System Instrumentation, Industrial Metering Equipment, Remote Sensor Interfaces, Precision Energy-Measuring Systems.
Isolated Current Monitoring
The MAX71071+T is appropriate for isolated current monitoring because its two 24-bit channels support current and voltage measurement while the pulse transformer provides an isolated data, clock, and power path to a compatible MAX71xxx host. Place the converter at the measurement side of the isolation barrier and route the host interface through the manufacturer-defined topology. This architecture can reduce the need for separate isolation components. Confirm the supported current range, gain path, conversion timing, and channel multiplexing before assigning the current-shunt signal. Verify isolation capacitance, creepage, filtering, and grounding against the conductor’s potential and the required safety category.
Рекомендуется
Isolated Voltage Measurement
The MAX71071+T can support isolated voltage measurement in metrology equipment that must retain a separation between the sensed voltage and the host controller. Its two measurement channels and 24-bit resolution suit precision measurement systems, while the pulse-transformer architecture transfers isolated data, clock, and power without requiring a separate isolation link for each function. The input conditioning network should present a signal within the converter’s documented range and bandwidth. Establish divider ratios, anti-alias filtering, input impedance, and reference accuracy from the application specification before schematic release.
Рекомендуется
Power-System Instrumentation
The MAX71071+T fits power-system instrumentation where current and voltage must be measured in an isolated domain and communicated to a supervising controller. Its dual-channel, 24-bit architecture supports coordinated metrology, while the pulse-transformer isolation path provides communication and isolated power through one defined mechanism. A compatible MAX71xxx host can handle command, control, and power coordination. The circuit must be designed around the exact input ranges, sampling behavior, timing, and isolation rating of the selected device. High-voltage layout should also observe the required separation distance and isolation-component rules.
Рекомендуется
Industrial Metering Equipment
The MAX71071+T is useful in industrial metering equipment that measures two electrical quantities and must communicate the results through an isolated interface. Its 24-bit dual-channel format provides a clear path for current plus voltage acquisition, and its integrated pulse-transformer isolation architecture reduces the number of separate isolation elements needed around the measurement subsystem. Pair the converter with a MAX71xxx host that supports the required commands and data format. Select input dividers or shunts so the full-scale signal remains within the documented operating limits, and validate accuracy over the required temperature and load range.
Рекомендуется
Remote Sensor Interfaces
The MAX71071+T can serve as the isolated measurement interface for remote sensor systems in which the sensed current or voltage must be transferred across a galvanic boundary. The pulse-transformer path carries data, clock, and power between the converter and a compatible MAX71xxx host, supporting an isolated subsystem architecture. This is useful when the sensor is referenced to a noisy, high-energy, or inaccessible circuit. The remote node still needs correct input conditioning and suitable creepage and clearance. Confirm the supported host timing, measurement bandwidth, and power-transfer requirements before treating the remote interface as a standardized sensor link.
Рекомендуется
Precision Energy-Measuring Systems
The MAX71071+T is appropriate for precision energy-measuring systems that combine isolated voltage and current acquisition with a digital metrology host. Its two channels and 24-bit resolution support high-resolution measurement, while the pulse-transformer isolation architecture maintains the separation between the measured power circuit and the processing electronics. A compatible MAX71xxx host supplies control and command functions. System accuracy will depend on the selected shunt, voltage divider, input filtering, reference behavior, calibration method, and synchronization requirements. Validate those parameters together because converter resolution alone does not define end-to-end metering accuracy.

Заметки по проектированию
Keep the measurement-side analog traces short, symmetrical, and isolated from the host-side digital interface. Route the pulse-transformer data and clock paths according to the manufacturer reference layout, with continuous return paths and no unintended crossings between the two isolation domains. Confirm creepage, clearance, isolation capacitance, and common-mode limits against the maximum working voltage before board fabrication.
Design the analog input network for the selected current or voltage range before assigning filtering values. Include the required shunt or divider, input protection, anti-alias filter, and grounding strategy, then verify channel-to-channel timing and settling. The 24-bit conversion resolution does not guarantee equivalent system accuracy; resistor tolerances, reference error, noise, and measurement bandwidth remain part of the end-to-end error budget.
Do not substitute a family member solely from the channel count and resolution. Check the ordering table, package geometry, pulse-transformer arrangement, MAX71xxx host protocol, accuracy grade, input range, conversion timing, and lifecycle status. Silergy and Analog Devices listings may share the headline architecture, but production equivalence still requires board-level and timing validation before changing the approved BOM.
Place input-conditioning components close to the converter pins and maintain a clearly defined isolation barrier across the board. Avoid placing high-voltage copper, test points, or mechanical fasteners in the separation region unless the applicable clearance rules permit them. Use the manufacturer’s isolation layout and component placement as the baseline, then verify the finished assembly for unintended conductive bridges between measurement and host domains.
