Located in Dresden, a semiconductor company ZMD AG (ZMDI) recently declared the launch of the ZSSC3026.
This premium 16-bit sensor signal conditioner (SSC) IC from ZMDI is effective for calibrating resistive sensor modules. The ZSSC3026 integrates an 18-bit DSP for linearization, high-precision amplification, 16-bit precision analog-to-digital conversion, in addition to calibration functions. This high-resolution sensor interface standard product offers significant features, which support battery-driven low-power devices. It is application-specific. Also, an ultra-low standby current and intelligent power-saving technology helps reduce overall power utilization. Besides being initially used for high resolution altimeter module applications, the ZSSC3026 is highly compatible with any device entailing low power consumption and high accuracy.
The ZSSC3026 is ideal for mobile devices as well as high precision industrial and medical applications such as industrial pressure and ambient assisted living sensors. It is used for enabling product development in complex environments due to its unique power supply rejection ratio (PSR), extended temperature range, and 4kV ESD protection.
ZMDI’s ZSSC3026 features up to 90dB of PSR; broad power supply range from 1.8V to 3.6V; improved ESD performance up to 4kV; low current consumption less than 1mA and stand-by current less than 100nA; Package options such as bare die, PQFN, bumped die; Noise-free, 16-bit output signal; Fully-corrected digital output signal for rapid system design and reduced component count; and integrated charge pump for programming internal memory.
The ZSSC3026 has operating temperature ranges from -40°C to +110°C and over ±0.01% FSO precision over the full temperature range. The ZSSC3026 offers a corrected temperature output calculated with an internal sensor effective for resistive bridge sensors.
An 18-bit internal digital signal processor running a correction algorithm provides digital compensation of signal offset, sensitivity, non-linearity and temperature. Calibration coefficients are enclosed within on-chip in a nonvolatile, multiple-time programmable memory. Internal memory programming can be achieved through an integrated charge pump.
ZMDI’s ZSSC3026 will be showcased at SENSOR+TEST 2012 from May 22-24, in Nuremburg, Germany.
