NTM88 maximum sensor samples per second via SPI

martijn-VB — Tue, 03 Feb 2026 21:26:11 GMT

Hello,

We're interested in using the NTM88 in one of our applications.

What is the maximum samples per second we can get from the pressure sensor and accelerometer? And what is the maximum response time of both sensors? (I couldn't find it in the datasheet, I might have overlooked it...)

With kind regards,
Martijn

Hello, please refer to the SPI section of the NTM88 manual for information on the protocol and frame format supported by the NTM88 UM11227 section 10.18, and the attached document.

Hope this helps.

Hi ErikaC,

I'm sorry, I've not formulated my question clear enough.
I was not looking for the SPI specific information but sensor specific.

How fast is the pressure sensor and accelerometer?
Does the pressure and accelero reading from the sensor update with 1Hz or with 1000Hz?

And what is the reponsetime of the sensors?
If the pressure or accelerration in the vehicle change very fast (ms range), how fast will the sensor reading out of the sensor change?

With kind regards,
Martijn

@ErikaCAny more information on this?

Can anyone point me in the right direction?
I'm not looking for SPI information but information about the actual sensing elements in the chip.

How fast is the pressure sensor and accelerometer?
Does the pressure and accelero reading from the sensor update with 1Hz or with 1000Hz?

And what is the reponsetime of the sensors?
