Low Power 16 Bit Sensor Signal Conditioner IC
2 Circuit Description
2.1. Brief Description
The ZSSC3016 provides a highly-accurate amplification of bridge sensor signals. The compensation of sensor
offset, sensitivity, temperature drift, and non-linearity is accomplished via an 18-bit DSP core running a correction
algorithm with calibration coefficients stored in an MTP memory. The ZSSC3016 can be configured for a wide
range of resistive bridge sensor types. A digital interface (SPI or I2C) enables communication. The ZSSC3016
supports two operational modes: Normal Mode and Command Mode. Normal Mode is supposed to be the mode
being used typically, in which the IC wakes up from a Sleep (low power) State, runs a measurement in Active
State and turns back automatically to the Sleep State.
2.2. Signal Flow and Block Diagram
See Figure 2.1 for the ZSSC3016 block diagram. The sensor bridge supply VDDB and the power supply for analog
circuitry are provided by a voltage regulator, which is optimized for power supply disturbance rejection (PSRR).
See section 1.4 for a graph of PSRR versus frequency. To improve noise suppression, the digital blocks are
powered by a separate voltage regulator. A power supervision circuit monitors all supply voltages and generates
appropriate reset signals for initializing the digital blocks.
The state machine controls the analog circuitry to perform the three measurement types: bridge, temperature, and
offset measurement. The multiplexer selects the signal input to the amplifier, which can be the external signals
from the input pins INP and INN, the internal temperature reference sensor signals, or an input short for
measuring offset. A full measurement request will trigger an automatic sequence of all measurement types and all
input signals, respectively. The Temperature Reference Sensor block is based on a PTAT temperature sensor.
The inherit (IC-fabrication related) device mismatch is suppressed by dynamic element matching technique.
