Part Number: ADS8319 Other Parts Discussed in Thread: ADS8862 , ADS8685W , ADS8685 Dear Technical Support Team,
Do you have latest devices to replace ADS8319(1ch/16bit/500ksps) + REF5045(4.5V) with alternative ADC ?
ADS8862 seems to be good option…
Part Number: REF5045A-Q1 Other Parts Discussed in Thread: ADS1299 Tool/software: 为了进一步的降低系统的输入参考噪声RTI, 在使用ADS1299时，想使用外部基准电压源，但选型时发现，当前REF5045没有增强型的物料，只有high grade level， 请问REF5045E的物料什么时候可以买?
我看4.096V的基准源更多一些，请问可以用4.096V的基准源吗，在进行ADC电压转换时，使用4.096V进行数据转换…
Thank you for the information. That clears my question about the REF5045. Can I know more about the buffer configuration and how did you arrive at the cutoff frequency of the buffer in the provided circuit ?
Part Number: ADS131A04 Hello,
I'm designing a design with ADS131A04 for current/voltage protection&metering application.
I plan to use adc @10ks/s sample rate and to fit all the signal dynamic I will need to be 20bits enob. Then I use an external…
Hi Daniel,
You can use an electrolytic capacitor and will not need to add an additional series resistor. These are only needed for low ESR ceramic capacitors. Just check the datasheet for the capacitor and confirm the ESR is in the range of 0.25ohm…
Hi Huriye,
The Iq of the REF5045 will not increase with Vin and it will still output 4.5V. So you can supply any voltage between 4.5V + 0.2V to 18V and have the same Iq across VIN in a no load condition. This includes 4.7V to 18V. The 0.2V is the drop…
Hi Murthy,
4.5V is a very niche voltage so we do have limited options. can you help share the use case of this voltage? We are always looking to expand the portflio.
Currently, we have the REF5045 which is a very high-precision device.
If you need…
Hello Thomas,
First, welcome to the TI E2E Community.
If using an external reference, please refer to Firgure 14 in the datasheet for the reference buffer. You can then generate the 3 voltages (4V, 2.5V, 1V) using a single low noise reference, such…
Part Number: ADS8699 Hi TI Technical Support Team,
I have designed a small 4 layer board with 2 18bit 100kHz ADS8699 and I am planning to use it to read voltage and current values from the device under test. The top and bottom layer are used for routing…
