Product details

The MAX111BCWE+: It carries ROHS3 compliance, which covers the current EU RoHS directive without exemptions.

14-bit sigma-delta at 50 S/s — where it fits

The differential input and internal MUX-ADC configuration let it reject common-mode noise on a two-channel sensor bridge, which is exactly the kind of signal that benefits from the sigma-delta's oversampling.

Single 5V supply, SPI, 16-SOIC

Both the analog and digital supplies run from a single 5V rail — no need for a separate analog LDO or a split supply. That simplifies the board layout and reduces BOM count. The SPI data interface is standard on almost every microcontroller, so hooking it up is a matter of four wires (SCLK, DIN, DOUT, CS). No parallel bus timing to worry about. It comes in a 16-SOIC wide-body package (7.50 mm width) — a common footprint that is easy to hand-solder or reflow. The tube packaging is typical for small quantities; if you need reel, check the alternate order code.

Frequently asked questions

What is the closest pin-compatible alternative to the MAX111BCWE+?

No pin-compatible alternative is listed in the manufacturer's cross-reference for this part. The MAX111BCWE+ is a unique order code; if you need a functional equivalent, you would need to evaluate other 14-bit sigma-delta ADCs in the same package, but pin compatibility is not guaranteed without a board layout change.

What is the MAX111BCWE+ used for?

It is a 14-bit sigma-delta ADC with a 50 S/s sampling rate, differential input, and SPI interface. Typical applications include low-frequency precision measurement such as weigh scales, temperature sensors, and pressure transducers where high resolution matters more than speed.
