Low Power, High Resolution 16-Bit
Sensor Signal Conditioner
ZSSC3026
Datasheet
Brief Description
The ZSSC3026 is a sensor signal conditioner (SSC)
integrated circuit for high-accuracy amplification and
analog-to-digital conversion of a differential input
signal. Developed for correction of resistive bridge
sensors and optimized for high-resolution altimeter
module applications, the ZSSC3026 can perform
offset, span, and 1st and 2nd order temperature com-
pensation of the measured signal. It can also provide
a corrected temperature output measured with an
internal sensor. The corrected measurement values
are provided at the digital output pins, which can be
configured as I2C™* (3.4MHz) or SPI (20MHz).
Digital compensation of the 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. Prog-
ramming the ZSSC3026 is simple via the serial
interface. An internal charge pump provides the
programming voltage. The interface is used for the
PC-controlled calibration procedure, which programs
the calibration coefficients in memory. The digital
mating is fast and precise, eliminating the overhead
normally associated with trimming external com-
ponents 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)
Internal auto-compensated temperature sensor
Digital compensation of individual sensor offset;
1st and 2nd order compensation of sensor gain
Digital compensation of 1st and 2nd order tem-
perature gain and offset drift
Intelligent power management unit
Layout customized for die-die bonding with
sensor for high-density chip-on-board assembly
Typical sensor elements can achieve accuracy of
better than ±0.10% FSO @ -40 to 85°C
