How do I configure the MAX14001 device for ADC measurements only?

To use this device for ADC measurements only (i.e. without the inrush current limiting circuitry), use the following hardware and firmware configurations:

Hardware:
  1. Connect 120kΩ resistor from ISET to GNDF
  2. Connect IFET to GNDF
  3. Connect 10nF capacitor from GATE to GNDF
Firmware:

Initialization Values:
 
MAX14001_write(MAX14001_WVR_adr,   0x294);
MAX14001_write(MAX14001_FLTEN_adr, 0x7e);   // disable MVL and FET
MAX14001_write(MAX14001_CFG_adr,   0x0c);   // Set filter to x8
 
MAX14001_write(0x10 + MAX14001_WVR_adr,   0x294);  // write verification register
MAX14001_write(0x10 + MAX14001_FLTEN_adr, 0x7e);   // write verification register
MAX14001_write(0x10 + MAX14001_CFG_adr,   0x0c);   // write verification register
 
ADC Read Command:
 
MAX14001_read(MAX14001_ADC_adr);
