Overview
Description
The ZSSC3224 is a sensor signal conditioner (SSC) IC for high-accuracy amplification and analog-to digital conversion of a differential or pseudo-differential input signal. Designed for high-resolution sensor module applications, the ZSSC3224 can perform offset, span, and 1st and 2nd order temperature compensation of the measured signal. Developed for correction of resistive bridge or absolute voltage sensors, it can also provide a corrected temperature output measured with an internal sensor. The measured and corrected sensor values are provided at the digital output pins, which can be configured as I2C (≤ 3.4MHz) or SPI (≤ 20MHz). Digital compensation of signal offset, sensitivity, temperature, and non-linearity is accomplished via a 26-bit internal digital signal processor (DSP) running a correction algorithm. Calibration coefficients are stored on-chip in a highly reliable, non-volatile, multiple-time programmable (MTP) memory. Programming the ZSSC3224 is simple via the serial interface. The interface is used for the PC-controlled calibration procedure, which programs the set of calibration coefficients in memory. The ZSSC3224 provides accelerated signal processing, increased resolution, and improved noise immunity in order to support high-speed control, safety, and real-time sensing applications with the highest requirements for energy efficiency.
Features
- Flexible, programmable analog front-end design,up to 24-bit analog-to-digital converter (ADC)
- Fully programmable gain amplifier for optimizing sensor signals: gain range 6.6 to 216 (linear)
- Internal auto-compensated 18-bit temperature sensor
- Digital compensation of individual sensor offset
- 1st and 2nd order digital compensation of sensor gain as well as 1st and 2nd order temperature gain and offset drift
- Programmable interrupt operation
- High-speed sensing: e.g., 18-bit conditioned sensor signal measurement rate >200s-1
- Typical sensor elements can achieve an accuracy of better than ±0.10% full-scale output at -40 to 85°C

About the EOC pin of ZSSC3224
Hi, Once the conversion gets completed the EOC pin of ZSSC3224 will be set high.. After that how the pin will get reset? is it after reading the data or after sending a new sampling command? Thanks

ZSSC3224 RES PIN
Dear, ZSSC3224 datasheet states "Alternatively, the RES pin can be connected and used to control safe resetting of the ZSSC3224. RES is active-low; a VDD-VSS-VDD transition at the RES pin leads to a complete ZSSC3224 reset." My question what the Reset Pulse width is? Another question, the ...

ZSSC3224 Radiated Susceptibility
Dear, good day! we use ZSSC3224 and MEMS bridge sensor to assemble pressure sensor. The result is excellent in basic function. But when we do the Radiated Susceptibility test, we find some issue. we select the I2C communication to read sensor output. the I2C communication is OK during whole test ...

A brief introduction and overview of IDT's (acquire by Renesas) sensor signal conditioner evaluation kits. Evaluation kits generally consist of three parts: a communication interface board, a device board, and a sensor simulator board - all connected together. A sophisticated software GUI accompanies the kit, enabling an engineer to learn how to use the part rapidly, do quick prototyping, and practice calibrations.
