Evaluating the ADMX3652 6½ Digit, ±20 V Digital Voltage Meter
User Guide | EVAL-ADMX3652
GENERAL DESCRIPTION
The 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) proto-
col. When the ADMX3652 connects with Analog Devices, Inc.,
EVAL-ADMX3652-INT evaluation board, it can be used as a porta-
ble measuring instrument that has two voltage input channels using
banana jack connectors. The measured data is output to a comput-
er through the UART to USB function on the EVAL-ADMX3652-INT.
An intuitive graphical user interface (GUI) tool is provided as well
for operating the module and capturing the data in the computer to
evaluate the performance of the ADMX3652.
