ZSSC4151CE4R

ZSSC4151CE4R is a programmable sensor signal conditioner (an analog front-end) from the ZSSC family. It is designed to condition signals from bridge-type sensors (e.g., RTDs, strain gauges, pressure sensors) for easy readout by a microcontroller.
Key points:
- Provides sensor excitation, precision amplification, and signal linearization/temperature compensation.
- On-chip programmable gain and offset, plus calibration memory to store sensor-specific parameters.
- SPI-like serial interface for configuration and reading the conditioned output.
- Intended for single-supply operation and compact packaging; RoHS-compliant (variant details vary by package).
Typical use cases:
- Industrial/instrumentation sensors, automotive sensors, and any application needing a compact, low-noise conditioned bridge signal.
Note:
- The CE4R suffix denotes a specific package/grade variant. Check the exact datasheet for electrical specs, pinout, operating range, and calibration/memory details for this variant.

Here are the typical features of ZSSC4151CE4R (Programmable Sensor Signal Conditioner):
- Fully integrated conditioner for resistive/bridge sensors with programmable gain, offset, and temperature compensation.
- On-chip excitation/biasing options for sensor bridges.
- User-programmable transfer function (including linearization) to match sensor characteristics.
- On-chip ADC with digital interface for programming and reading results (serial control interface).
- Output is ratiometric to the supply, with low-noise analog output.
- Wide supply and temperature range suitable for rugged environments (common ranges cover ~2.7–5.5 V and -40 °C to +125 °C).
- Low power operation with standby/low-current modes.
- Small package option (CE4R) suitable for compact designs.
- Calibrated performance reduces sensor drift and shortens system calibration time.
Note: For exact electrical specs (gain range, ADC resolution, interface protocol, and excitation current), refer to the official datasheet.

Pin count: 8 pins (8-pin package).
