1 Module introduction

AD7606yes16A,8Channel synchronous sampling, sampling rate per channel up to200kSPSAn analog to digital data acquisition chip with analog input clamp protection, two order anti aliasing filter, and tracking holding amplifier,16Bit charge redistribution successive approximationADCDigital filter,2.5VReference voltage source, reference voltage buffer, high-speed serial and parallel interface. Use5VSingle power supply, with on-chip filtering and high input impedance, and therefore no need to drive operational amplifiers and external bipolar power supplies; anti aliasing filters3 dBCutoff frequency is22 kHzWhen the sampling rate is200kSPSWhen it has40 dBAnti aliasing suppression; the input clamp protection circuitry guarantees input tolerance to ±16.5VVoltage. It can be applied to power line monitoring and protection, multiphase motor control, instrumentation and control, multi axis positioning, data acquisition and other systems.

The main features of the module are as follows:

(1)function:16position,8passagewaysynchronizationSampling,sampling rateaccessible200kSPSModulusADAcquisition module.

(2)ADdigit:16A.

(3)Channel number:8passagewaysynchronizationInput, synchronous sampling.

(4)Maximum sampling rate:200kSPS. Support6Oversampling modeRespectively2Times,4Times,8Times,16Times,32Times and64By averaging the acquired data by oversampling, the jitter of the input analog is effectively reduced. The larger the oversampling rate is, the lower the sampling rate is.

(5)data interface:16Bit bus interface/8Bit bus interface/SPIserial interfaceUse2.54The spacing of the double pin interface; the interface level can be5Vperhaps3.3VThrough a short circuit cap on a module, orIOPort programming control.
