Feature: *3.3V or 5.0V DC power supply. *MCU interface: SPI. *Main ADC chip: TM7705 (AD7705 chip is fully compatible) *LM285-2.5 external reference voltage. Part peers using low-end domestic TL-431 is not a number as a reference, temperature stability and accuracy of the level difference. Please sights. *The input circuit with a divided resistor and RC filter, enabling customers to change their own gain range. *Chip programmable gain amplifier with a gain range: 1-128 times. *Chip buffer amplifier input with direct connection Sensor.

This module described here is based on ADS9850, a CMOS, 125MHz, and Complete DDS Synthesizer. The AD9850 is a highly integrated device that uses advanced DDS technology coupled with an internal high speed, high performance, D/A converter and comparator, to form a complete digitally programmable frequency synthesizer and clock generator function. All the external components which are needed are integrated on the board and the designer don’t need to care more about the detailed design of ADS9850. The designer only needs to add the power and control signals to this module to driver this module
