Hello,
I received a question about LTC2986 from our customer. He is checking LTC2986 by following setting.
When the customer sets YOKOGAWA 2553A to 0.0 deg C. The measurement result of LTC2986 is -0.5 deg C.
Then he sets 2553A to 100.0 deg C. The measurement…
I'm looking through the LTC2986 datasheet and I'm a little bit confused about the external configuration for the single ended and differential thermistors.
If I understand correctly, the device has ten channels, but can only be connected to three…
Hi,
I have a couple of questons about the direct ADC mode of LTC2986. Please take care of this case.
- What is the maximum sampling speed of internal 24 bit ADCs in the direct ADC mode?
- How can I know conversion start and finish in the direct ADC mode…
Question:
Are the LTC2983/LTC2984/LTC2986/LTC2986-1 interchangeable?
Answer:
The LTC298x family consists of pin and software compatible parts that differ in their number of channels and inclusion of EEPROM. LTC2983 (without EEPROM) and LTC2984 (with EEPROM…
We have a design based on the LTC2983, but currently having trouble procuring them for an upcoming build. I see that the LTC2984 and LTC2986 are very similar parts, with the addition of EEPROM for storing data through power cycles. Assuming we don't need…
你好，要做到0~200℃全温0.5℃精度的话，建议使用LTC2986+K型热电偶做测量电路，LTC2986通过隔离SPI与MCU交换数据。电源和SPI隔离部分建议使用ADP1031，485隔离器建议使用ADM2463E。
Hi Botnic,
Differential mode has two advantages for diodes:
1) If COM was tied to a different potential than GND for other sensors, using a differential reading for the diode ensures the voltage is sensed correctly.
2) If the ground connection between…

Hi akashk,
If you need all 20 channels, the LTC2983 is firmware compatible with the exception that it does not have the EEPROM of the LTC2984. This means any channel configs, custom sensor table data, etc. would have to be reloaded on power-up from the…
That sounds like a good plan to me. The single ended input range is 0-1.25V (VREF/2) so you're good to go there and the input buffers are very high impedance so there shouldn't be any loading of the 1k resistance.
I'm assuming you need all 20…
