ADMX3652: 6½ Digit, ±20 V Digital Voltage Meter

The ADMX3652 6½ digit, digital voltage meter (DVM) offers fast throughput (1 kSPS), flexible measurements (manual or automatic selection range), and trustworthy results (25 ppm of measurement accuracy for 90 days under 2 V range).

The ADMX3652 provides a compact solution with the most common DVM measurements. With long measurement times, the norm for high integration precision applications—a simple, reliable, pocketable device that can save system space—is a popular addition to the toolbox of engineers.

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 independently 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.
