Product Details Supplier Info More products

Rutronik is now offering ZMDI’s ZSSC3053 differential sensor signal conditioner (SSC) for microcontroller-based sensor systems in industrial, medical, consumer and white-goods applications.

The chip is adjustable to almost all resistive bridge sensor types and provides amplification and sensor-specific correction of millivolt-level DC sensor signals.

The feature-optimised CMOS IC is compatible with nearly all resistive sensor elements and millivolt-level sources.

It supports the IC and SPI standard digital interfaces with a very low number of discrete external parts.

In IC mode, the ZSSC3053 offers two additional switch outputs, while programmable slave addresses enable multi-slave operation.

Using ZMDI’s single pass ‘one-shot’ calibration, the microcontroller can custom calibrate the sensor in a very short time, typically a fraction of a second.

The microcontroller can even recalibrate in system if desired.

Eliminating the need for external trimming or laser tuning, the ZSSC3053 helps to reduce the overall bill of materials as well as manufacturing costs and can shorten time to market.

Digital compensation of offset, sensitivity, temperature drift and nonlinearity is accomplished by a 16-bit RISC microcontroller running a correction algorithm with calibration coefficients stored in an Eeprom.

The ZSSC3053 operates on a voltage range of 2.7V to 5.5V and over a temperature range of -25C to +85C.

The ADC offers 15-bit precision and accuracy is +/-0.1 per cent of full scale over the full temperature range.

The ZSSC3053 evaluation kit is also available from ZMDI, which includes an evaluation board, TSSOP14 samples and software.

The ZSSC3053 comes in a TSSOP14 package.

Volume production is planned for Q2/2010 with engineering samples available now.
