Features
Brief Description
The ZMD31010 is a CMOS integrated circuit for
highly-accurate amplification and sensor-specific
correction of bridge sensor signals.
•
•
•
Digital compensation of sensor offset, sensitivity,
temperature drift and non-linearity
Accommodates differential sensor signal spans up
to 36mV/V
Digital compensation of sensor offset, sensitivity,
temperature drift and non-linearity is accomplished via
an internal digital signal processor running a
correction algorithm with calibration coefficients stored
in a non-volatile EEPROM.
Digital one-shot calibration via one-wire interface:
quick and precise
•
•
Internal temperature compensation reference
Output options: ratiometric analog voltage,
absolute analog voltage, digital one-wire-interface
Supply voltage 2.7...5.5V, with external JFET
5.5...26.5V
Measured values are provided at the analog voltage
output or at the one-wire-interface.
•
•
The digital one-wire-interface can be used for a
simple PC-controlled calibration procedure, in order to
program a set of calibration coefficients into an on-
chip EEPROM. Thus a specific sensor and a
ZMD31010 are mated digitally: fast, precise and
without the cost overhead associated with trimming by
external devices or laser.
Current consumption, depending on adjusted
sample rate, 0.15...1.5mA
•
•
•
Operation temperature –50...+150°C
Fast response time: 1ms
High voltage protection up to 30V with external
JFET
Benefits
• Evaluation kit available, containing PCB, SOP8
samples, software, documentation
• Application support for industrial mass
calibration available
•
•
No external trimming components required
PC-controlled configuration and calibration via
one-wire interface - simple, low cost
High accuracy (±0.1% FSO @ -25 to 85°C;
±0.25% FSO @ -40 to 125°C)
• Quick circuit customization possible for large
production volumes
