Hi
I like to understand more about this ADS1274 which is ideal for 3 channel sensor (AMR) with 4thl temperature channel , however, I like to reduce current to a minimum as possible via reduced CLK and power-up and down behaviour.
The sample rate for all 4 channel is 40mSec, I like to put this device to power down but unclear how quickly the SD recover from power up and thus ready for next capture and then power down. I mean internal analogue circuit settle time from power up.
How long is active mode and power down mode?
I'm limited by the clock of 1MHz from MSP430 (SMCLK output from GPIO) to keep power down. How this impact the sampling operating in Sigma Delta using non-standard clock.
I would be grateful for your input based on experience with this device and any issue related to CLK and powerup-down I need to be aware of?
