Tool/software:

Hi team,

My customer asked for ADC solutions and we need BU's help to suggest suitable solutions.

Below list is their requirement:

1. 6 channels

2. Resolution is 16 bits

3. sample rate is no concern

4.there are 5 different output request:

Voltage range between 1V and 5V
Voltage range between 0V and 10V
Voltage range between -5V and 5V
Voltage range between -10V and 10V
Current range between 4mA and 20mA

According to customer's request, they hope one device could cover all request. If not, please provide each TI suitable solutions.

Thanks

Hi Paul,

The ADS8668 is a good fit to the requested specifications. This device is 8-channel, but can be used in the requested configurations.

Kyle,

Good day. customer provide new requirement, is ADC084S021 ok for them?

Our ADC should support negative input voltage and negative input current.

Customer just needs cheapest solution 4CH ADC solution. And below table is their analog input specification.

Please advise.

Thanks

Hi Paul,

The TLA2024 is the most cost-effective 4-channel ADC we offer in the portfolio, but the AIN range is from GND to VDD.

The ADS8634 is the most cost effective 4-channel device in the portfolio support negative input analog input ranges up to +/-10V with a scalable input to +/-5V.
