ADS1256 8 channel data acquisition AD module /24 Bit Multichannel acquisition system 30Khz for Electronic Design Contest
ADS1256 Description
One: Module Introduction
ADS1256 module ADS1256 REF3225,8 Road 24 AD acquisition.
II: Wiring diagram
Three: wiring instructions
1, 5V port: supply voltage 5V
2, SC-SCL
DO-DRDY
DR-SCLK
3,0 ~ 7 Port: AD channel 0-7
Module Introduction
1, power supply voltage: 5V
2, a single-ended voltage acquisition: 0 ~ 5V or Difference acquisition -5 ~ 5V
Note: negative voltage differential acquisition means: Channel 0- Channel 1 = negative voltage is required for each channel to be positive.
The channels A and B on the ground is a negative voltage is not collected, please note!
For example: Channel 0 (2.5V) - Channel 1 (5V) = - 2.5V, this time to measure
Channel 0 (2.5V) - Channel 1 (-2.5V) = 5V at this time can not be measured, and will burn Channel 1, do not try
In short: on the ground to a negative voltage is not collected, please note!
3: TI imported chips ADS1256
4: Professional 2.5V reference: REF3225 (4ppm / C)
Non-REF315 (15ppm / c), a non-LM285-2.5 ( - 20ppm / c)
5, programmable gain amplifier: 1 to 64 times
6, low non-linearity: - 0.0010%
7, Sampling rate: Highest 30KSPS
8: up to 23-bit noise-free precision

Serial data collection:
Redefine modules, is able to co-direct the secondary development of products, rather than learning boards, electronic studio would dream AD, DA module reseal provide schematics and package library, the module is seen as an in-line device , directly into your project, you do not need to re-create the board.
