Other Parts Discussed in Thread: ADS7280
Hi,
I have a problem with writing to ADS7280 CMR. No matter what I write to the A/D converter I recieve both channels and eaven when I don't send the command Read data (1101b). Is there some special set up…
Other Parts Discussed in Thread: ADS7280 Hi...
I have configurate the ADS7280 with the simple code below:
SEL_AD = 1; //FS/CS delay_us(1); START_AD = 1; // CONVST delay_us(1); SCK = 0; delay_us(30); SEL_AD = 0; delay_us(30); SDO = 1; delay_us…
Hello,
I did a quick parametric search that resulted in 10 devices
I would recommend the ADC122S021 , this is a 12 bit device, but with oversampling you can get a 14 bit resolution if necessary.
There is also the ADS7280 which is 14 bits.

Other Parts Discussed in Thread: ADS7280 I have an application where I would like to control the ADS7280 with just a simple 4-wire SPI interface (SCLK,SDI,SDO,CS). In other words, I would like to initiate acquisition and conversion sequences through the…
Other Parts Discussed in Thread: ADS7280 , TLC3544 I've been trying to configure the ADC (TCL3544), connected to a dsPIC33 via SPI. The uC is sending the signal properly but the ADC is not respondig. Already tried with the Hardware Default Mode and Software…
Hello Chris,
We have a few parts that may fit your needs. ADS7230, ADS7280, or ADS8330. But, I would caution you on the signal conditioning circuitry boosting the input signal up to 10V. This is going to greatly limit the number of devices to use.…
I need help determining the accuracy of a measurement system
I’m having trouble getting my hands around the accuracy of my measurement design. I’ve attached the schematic. There are 4 analog inputs (CH1± …. CH4±). Using relays and resistor dividers…
