ZMD31150 is a CMOS integrated circuit for high-accurate amplification and sensor-specific correction of bridge sensor signals. Digital compensation of offset, sensitivity, temperature drift and non-linearity is accomplished via a 16-bit RISC micro-controller running a correction algorithm. The ZMD31150 is adjustable to nearly all resistive bridge sensor types, e.g. piezo-
The ZMD31150 is a CMOS integrated circuit designed for high‑accuracy amplification and correction of bridge sensor signals. It provides digital compensation of offset, sensitivity, temperature drift and non‑linearity via a 16‑bit RISC micro‑controller, and supports analog voltage (0‑5 V), ZACwire™ one‑wire, or °C serial bus outputs.
The device is suited for automotive and industrial applications such as high‑pressure, low‑pressure, MAP, oil‑pressure and tire‑pressure sensors. Evaluation kits and mass‑calibration support are available, and ZMD offers worldwide sales and technical assistance.
