Description:The AD7705 is a complete 16-bit, low-cost, Sigma Delta ADCs intended for dc and low-frequency ac measurement applications. LC AD7705 module is AD acquisition module, there are two full differential input channels. AD7705 inside with a programmable gain amplifier, chip internal input with buffer amplifier, so can directly connected sensor. Their low power (1 mW max @ 3 V) allows them to be used in loop-powered, battery-powered or locally-powered applications. The on-chip Programmable Gain Amplifier with gain settings from I through 128 can accommodate both low-level and high-level analog inputs with no external signal conditioning hardware. This ADC board is able to sample an analog signal with 16 bits at 500 samples per second.
