Benefits
• Separate digital compensation of sensor offset, sensitivity,
The ZMD31012 combines the benefits of two single ZMD31010.
temperature coefficient and non-linearity
• Accommodates differential sensor signal spans from 1.2mV/V
to 60mV/V for two inputs
• Dual ZACwire one-wire interface
• No external trimming components required
• PC-controlled configuration and calibration via one-wire interface
– simple, low cost
TM
• Internal temperature compensation reference
via bandgap PTAT*
• High accuracy (±0.1% FSO @ -25°C to 85°C;
±0.25% FSO @ -40°C to 125°C)
• Optional sequential output of both temperature and bridge
readings two ZACwire digital output
• Single pass calibration – quick and precise
TM
• Output options: ratiometric analog voltage, absolute analog
voltage, digital one-wire-interface
Due to the two independent channels the ZMD31012 provides
a perfect fit for the following selected samples:
• Supply voltage 2.7V to 5.5V, with external JFET 5.5V to 30V
• Current consumption 2mA
• Operation temperature -50°C to +150°C
• Fast response time: 1ms
• Applications that require redundancy
• Measurement of differential pressure
• Flow Sensors
• High voltage protection up to 30V with external JFET
• Chopper stabilized true differential ADC
• Buffered and chopper stabilize output DAC
*Proportional to absolute temperature
Brief Description
The ZMD31012 consists of two ZMD31010 dies in a standard
SSOP14 packages. ZMD31012 is a CMOS integrated circuit, which
enables easy and precise calibration of resistive bridge sensors via
EEPROM. When mated to a resistive bridge sensor, it will digitally
correct offset and gain with the option to correct offset and gain
coefficients and linearity over temperature. A second compensa-
tion can be enabled for temperature coefficients of gain or offset
• ZMD31010 Development Kit can be used
• Support for industrial mass calibration will be available
• Quick circuit customization possible for large production volumes

serial interface to the host computer and is easily mass calibrated in
a Windows® environment.
Once calibrated, the output SIG pin can provide selectable 0V to
