FS511
General Description
FS511 is a high resolution analog-to-digital (ADC) chip. The core of the chip is an 18-bit resolution ΔΣ ADC. Besides the ΔΣ ADC, the FS511 consists of switching circuits, two operational amplifiers, two digital filters, crystal oscillation circuit, digital control logic, and microprocessor interface. Under 5V working voltage, this chip consumes 1.2mA power.
