Brief Description
The RBicdLiteTM 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 is accomplished via an internal digital signal processor running a correction algorithm with calibration coefficients stored in a non-volatile EEPROM.

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
• Digital calibration and configuration via one-wire interface –
   quick and precise
• 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
• Supply voltage 2.7 to 5.5V; with external JFET, 5.5 to 30V
• Fast power-up to data out response; output available 5ms after
   power up
• Current consumption depends on programmed sample rate;
   1mA down to 250µA (typical)
• Operation temperature: –50°C to +150°C
• Fast response time: 1ms (typical)
• High voltage protection up to 30V with external JFET
• No external trimming components required
• High accuracy (±0.1% FSO @ -25 to 85°C;
   ±0.25% FSO @ -50 to 150°C)
