ZPA4756-0311A-R

Overview

The ZPA4756-0311A-R is a high-precision digital barometric pressure sensor designed for absolute pressure measurement from 300 to 1100hPa. It integrates a 24-bit output and an internal averaging function to provide stable, low-noise data over a wide operating temperature range of -40 to 85 degrees Celsius. This surface-mount component is optimized for low-power operation, drawing only 0.046mA during active runs and 2.2uA in standby.

Why Choose This Part

This sensor offers exceptional power efficiency and high precision with +/-0.04 percent accuracy and a 24-bit resolution. The dual-interface support for both I2C and SPI, combined with an integrated interrupt function and simple average calculation, reduces the processing overhead on the host microcontroller.

Applications

Getting Started

Interface the sensor via the 8-pin surface-mount package to a microcontroller using either the I2C or SPI bus. Ensure the supply voltage is maintained between 1.7V and 3.6V, and utilize the Data Ready interrupt pin to trigger pressure readings without constant polling of the 24-bit registers.

Also Consider

LPS22HB STMicroelectronics - Provides a high-performance 24-bit absolute pressure output in a similarly compact footprint.

MS5607-02BA TE Connectivity - Offers high-resolution altitude measurements with an integrated temperature sensor for compensated output.
