ADMX3652 Digital Voltage Meter

ADI's ADMX3652 is a 6½ digit, ±20 V, dual-channel digital voltage module with a small form factor that can be easily integrated into a system. The module provides three measurement ranges that can be selected manually or automatically according to the input voltage. All operations are implemented through universal asynchronous receiver-transmitter (UART) communications with the Standard Commands for Programmable Instruments (SCPI) protocol. When the ADMX3652 connects with Analog Devices’ EVAL-ADMX3652-INT evaluation board, it can be used as a portable measuring instrument with two voltage input channels using banana jack connectors. The measured data is output to a computer through the UART to USB function on the EVAL-ADMX3652-INT. An intuitive graphical user interface (GUI) tool is also provided for operating the module and capturing the data in the computer to evaluate the performance of the ADMX3652.

The current consumption of the ADMX3652 is only around 310 mA for a 5 V power supply in stable working mode. Compared to complex instruments with numerous settings, the ADMX3652 requires simple settings with a preset configuration for a typical application. Electrically, the ADMX3652 is compatible with 1.8 V, 2.5 V, and 3.3 V interfaces, using an internal independent logic supply.

The ADMX3652 is available in a 77.70 mm × 46.30 mm × 20.15 mm, 10-lead module package with operating temperature specified from 0°C to +45°C.
