Understanding how to Interface to 16 Bit Digtal Pressure Sensors

One of AVSensors’ key advantages is its use of multi-chip technology, which provides exceptional flexibility in design. By integrating multiple chips into a single sensor package, AVSensors delivers a broad range of digital pressure sensors that balance resolution, performance, and cost to meet the varied requirements of OEM applications.

This 16 bit mixed-signal ASIC engineered to handle the entire signal chain for resistive bridge pressure sensors, eliminating much of the external circuitry engineers would otherwise need to design. It integrates dual 16-bit ADCs for simultaneous pressure and temperature acquisition, a programmable analog front end with adjustable gain and offset cancellation, and a DSP capable of up to third-order polynomial correction to linearize sensor output. Supply rails from 2.7 V to 5.5 V make it flexible for both 3.3 V and 5.0 V systems, while the architecture’s ratiometric design ensures excellent PSRR and measurement stability.
