ZSSC3016
Datasheet
Brief Description
The ZSSC3016 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 ZSSC3016 can perform offset,
span, and 1st and 2nd order temperature compensa-
tion 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)
running a correction algorithm. Calibration coeffici-
ents are stored on-chip in a highly reliable, non-
volatile, multiple-time programmable (MTP) memory.
Programming the ZSSC3016 is simple via the serial
interface and the PC-controlled calibration software
provided in the IDT Development Kit. The interface
is used for the PC-controlled calibration procedure,
which programs the set of calibration coefficients in
memory. The digital mating is fast and precise,
eliminating the overhead normally associated with
trimming external components and multi-pass
calibration routines.
Features
• Flexible, programmable analog front-end design;
up to 16-bit scalable, charge-balancing, two-
segment analog-to-digital converter (ADC)
• Fully programmable gain amplifier for optimizing
sensor signals: gain range 14 to 72 (linear factor)
• Internal auto-compensated temperature sensor
• Digital compensation of individual sensor offset;
1st and 2nd order digital compensation of sensor
gain
• Digital compensation of 1st and 2nd order temper-
ature gain and offset drift
• Intelligent power management unit
• Typical sensor elements can achieve accuracy of
better than ±0.10% FSO @ -40 to 85 °C
Benefits
