ADS8881: Bipolar Input

Nam, Dino

Part Number: ADS8881
Other Parts Discussed in Thread: ADS8900B

Tool/software:

Dear team,

Currently, My customer are using LTC2328-18 for their application.

To replace this device, I found ADS8881 with similar function but this device is unipolar input.

Is there any solution to replace LTC2328-18? please let me know your opinion.

Thank you.

Hi Dino,

The ADS8881 and ADS8900B are the most similar to the LTC device. However, they are both unipolar as you have mentioned. This E2E post tags an app note that may be referred to for bipolar to unipolar conversions. ADS8900B has very low noise.

Alternatively, ADS9817, 18-bit, 2MSPS/CH, 8 channel, MUX, SAR ADC are new and do have bipolar input range up to +-12V.

Best regards,

Samiha
