• On-chip power supply regulator for load-cell and ADC analog power supply.
• On-chip oscillator requiring no external component with optional external crystal.
• On-chip power-on-reset.
• Simple digital control and serial interface: pin-driven controls, no programming needed.
• Selectable 10SPS or 80SPS output data rate.
• Simultaneous 50 and 60Hz supply rejection.
• Current consumption including on-chip analog power supply regulator: normal operation < 1.5mA, power down < 1A.
