Description
The HX717 is a precision 24-bit analogto-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. The input multiplexer selects either Channel A or B differential input to the low-noise programmable gain amplifier (PGA).
Features
- Two selectable differential input channels
- On-chip active low noise PGA with selectable gainof 8, 64 and 128
- On-chip power supply regulator for load-cell andADC 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 10, 20, 80 or 320SPS output data rate
- Simultaneous 50 and 60Hz supply rejection
- Current consumption including on-chip analogpower supply regulator: normal operation < 1.5mA, power down<1uA
- Operation supply voltage range: 2.7 ~ 5.5V
- Operation temperature range: -40 ~ +85C
- 16 pin SOP-16 package
