I'm working on a project that requiers high precision gyro Z axis on the atmega328 chip, in the mpu6050 lib it is explained that when you set dlpf mode to 0, the low pass filter is disabled and sample rate is set to 8kHz.

That's what the invensense docs says as well, but then what is the purpose of the option to set DLPF to 0 and sample at 8000Hz while the bandwidth is only 256kHz?

For some reason the output on 256kHz is very stable as if it was going through the low pass filter.

I know I could sample directly at 1kHz but this is wasting way too much my system recources, so sampling every 3.9ms at 256Hz is ok for me.

Any help is appreciated.
