ZSSC3036
Datasheet
Brief Description
The ZSSC3036 is a sensor signal conditioner (SSC)
integrated circuit for high-accuracy amplification and
analog-to-digital conversion of a differential input
signal. Designed for high-resolution altimeter module
applications, the ZSSC3036 can perform offset,
span, and 1st and 2nd order temperature compen-
sation of the measured signal. Developed for correc-
tion of resistive bridge sensors, it can also provide a
corrected temperature output measured with an
internal sensor.
The measured and corrected bridge 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
an 18-bit internal digital signal processor (DSP) run-
ning a correction algorithm. Calibration coefficients
are stored on-chip in a highly reliable, non-volatile,
multiple-time programmable (MTP) memory. Pro-
gramming the ZSSC3036 is simple via the serial
interface. The IC-internal charge pump provides the
MTP programming voltage. The interface is used for
the PC-controlled calibration procedure, which pro-
grams the set of calibration coefficients in memory.
The ZSSC3036 provides accelerated signal process-
ing in order to support high-speed control, safety,
and real-time sensing applications. It complements
IDT’s additional ZSSC30x6 products.
