Brief Description
The RBicdLite™ is adjustable to nearly all piezo-resistive bridge sensors. Measured and corrected bridge values are provided at the SIG™ pin, which can be configured as an analog voltage output or as a one-wire serial digital output.
FEATUREs
• Digital compensation of sensor offset, sensitivity,
temperature drift, and non-linearity
• Programmable analog gain and digital gain;
accommodates bridges with spans < 1mV/V
and high offset
• Many diagnostic features on chip (e.g., EEPROM
signature, bridge connection checks, bridge short
detection, power loss detection)
• Independently programmable high and low
clipping levels
• 24-bit customer ID field for module traceability
• Internal temperature compensation reference (no
external components)
• Option for external temperature compensation
with addition of single diode
• Output options: rail-to-rail ratiometric analog
voltage (12-bit resolution), absolute analog
voltage, digital one-wire interface
• Fast power-up to data out response; output
available 5ms after power-up
• Current consumption depends on programmed
sample rate: 1mA down to 250A (typical)
• Fast response time: 1ms (typical)
• High voltage protection up to 30V with
external JFET
