Part Number: TLC2574 Tool/software: Hello,
I have my ADC and Controller both on different PCBs.
ADC is on High Voltage Section(36KV) so to isolate I wanted to use Fiber Optic links to communicate with ADC.
Limitation of Fiber Optic links is, they…
Other Parts Discussed in Thread: TLC2574 We have a design that is using the TLC2574 in single ended mode. We seem to be seeing a positive offset of ~ 50-100 mV on our expected readings at normal room temperatures. This relates to 10-20 ADC counts. We…
Other Parts Discussed in Thread: TLC2574 We have a new design using the TLC2574 in single ended mode. We use as reference voltage the ADR434AR with adjustable output, set to 4.0V. We connected several external sources and noticed that the readings are…
Other Parts Discussed in Thread: TLC2574 Hello,
I am trying to use the TLC2574 in the REPEAT SWEEP mode using CS as the trigger and the 00-11-22-33 conversion sequence. The data sheet suggests that to begin conversion of a channel, a SELECT command…
Part Number: TL082 Other Parts Discussed in Thread: TLC2574 Tool/software: I am confused with the C192 capacitor, the C192 capacitor will lead the positive feedback of the input signal of TL082.
Normally, we design the circuit will avoid the positive…
Hi Wenting,
Most of the precision ADC portfolio is based on higher speed products using an SPI interface. Such devices include TLV2544 family, the TLC2574 family and the ADS8201. You could also look into the ADS7142 which is an I2C interface. Another…
Hi Stephen,
Assuming you are going by figures 11 or 12, you are not overlooking anything. That is simply the way these devices were designed to work if /CS or FS initiates the conversion. If you can use the CSTART pin to initiate the conversion as in…
