Other Parts Discussed in Thread: ADS1261EVM
Hi sir,
For the uA solution of ADS1260:
-R-shunt = 500mΩ for much buffer of avoiding noise.
-Vref = 4.5V
-Vshunt_Max = Isense_Max x Rshunt = 50mA x 500mΩ = 25mV
-Dynamic Range = Isense_Max / Iresolution = 50mA / 1uA = 50000
-Vresolution = Vsense_Max / Dynamic Range = 0.5uV
Here is my Schematic for ADS1260:
NOTE:
(1)LED_5V and GND_LDO (5V ) are from TPS7A4701RGW.
(2)REFP and REFN (4.5V) are from REF6045DGK.
Is this schematic alright to use ?
If something I missed, please let me know.
