Circuit Description Note: This data sheet provides specifications and a general overview of ZSC31150 operation. For details of operation, including configuration settings and related EEPROM registers, refer to the ZSC31150 Functional Description. 2.1 Signal Flow The ZSC31150’s signal path includes both analog (shown in blue in Figure 2.1) and digital (pink) sections. The analog path is differential; i.e., the differential bridge sensor signal is handled internally via two signal lines that are symmetrical around a common mode potential (analog ground = VDDA/2), which improves noise rejection. Consequently, it is possible to amplify positive and negative input signals, which are located within the common mode range of the signal input.

The multiplexer (MUX) transmits the signals from either the bridge sensor, the external diode, or the separate temperature sensor to the analog-to-digital converter (ADC) in a specific sequence (the internal pn-junction (TS) can be used instead of the external temperature diode). Next, the ADC converts these signals into digital values. The digital signal correction takes place in the calibration microcontroller (CMC). It is based on a correction formula located in the ROM and sensor-specific coefficients stored in the EEPROM during calibration. Depending on the programmed output configuration, the corrected sensor signal is output as an analog value or in a digital format (I2C or ZACwire™). The configuration data and the correction parameters can be programmed into the EEPROM via the digital interfaces. 2.2 Application Modes For each application, a configuration set must be established (generally prior to calibration) by programming the on-chip EEPROM regarding to the following modes: Sensor Channel Sensor mode: ratiometric bridge excitation in voltage or current supply mode. Input range: the gain adjustment of the AFE with respect to the maximum sensor signal span and the zero point of the ADC have to be chosen. An additional analog offset compensation, the Extended Zero-Point Compensation (XZC), must be enabled if required; e.g., if the sensor offset voltage is close to or larger than the sensor span. Resolution/response time: The ADC must be configured for resolution and conversion settings (1st or 2nd order). These settings influence the sampling rate, signal integration time, and, as a result, the noise immunity. Temperature Temperature measurement: the source for the temperature correction must be chosen. |
