Description
MINIMUM TECH FEATURES
- Output Sensitivity: 1.0 ± 0.1 mV/V
- Measurement Resolution: 24-bit ADC
- Operating Current: ≈1.5 mA
- Temperature Range: −40°C to +85°C
- CMRR: 100 dB
- Data Output: 2-wire digital interface (DOUT, SCK)
DESCRIPTION
- Offers 24-bit precision for high-resolution load and pressure measurements.
- Built-in low-noise programmable gain amplifier (PGA) ensures stable readings even from tiny signal changes.
- Two sampling rates:
- 10 SPS (high-resolution mode)
- 80 SPS (fast-response mode)
- Simplifies circuit design by eliminating the need for external amplifiers.
- Supports easy interfacing with microcontrollers through a simple 2-wire protocol.
- Analog supply voltage: 2.6–5.5 V
- Digital supply voltage: 2.7–5.5 V
- PGA Gain options: 128, 64, 32
- Auto power-down mode when SCK is inactive.
- Suitable for single-channel or dual-channel load cell systems.
