Product details

What this chip is — capacitance-to-digital converter for proximity and level sensing

The AD7151BRMZ-REEL is a single-channel capacitance-to-digital converter from Analog Devices. It takes a capacitive input (via a voltage input structure) and outputs a digital representation of the measured capacitance. The part draws only 70 µA supply current, making it a fit for battery-powered or loop-powered sensor nodes that need to detect proximity, touch, or fluid level without mechanical contacts. The ROHS3 compliance simplifies export and environmental reporting.

The 70 µA supply current is the headline rating that separates this part from general-purpose ADCs.

Package and mounting — 10-MSOP, surface-mount only

The part is supplied in a 10-MSOP package (3.00 mm body width, 0.118" pitch). It is surface-mount only — no through-hole option.

Frequently asked questions

What is the closest alternative to AD7151BRMZ-REEL?

The AD7150BRMZ-REEL is the dual-channel version of the same capacitance-to-digital converter family. It shares the same 10-MSOP package, 70 µA supply current, and -40°C to 85°C temperature range. The AD7151 is single-channel; the AD7150 is two-channel. Choose the AD7150 if you need two capacitive inputs; otherwise the AD7151 is the same core.

Is AD7151BRMZ-REEL RoHS compliant?

Yes, it is ROHS3 compliant.
