PRODUCTION DATA
7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
0 | 0 | 0 | DIS OVR ON LSB | SEL OVR | GLOBAL POWER DOWN | 0 | CONFIG PDN PIN |
Bits 7-5 | Always write 0 | ||
Bit 4 | DIS OVR ON LSB | ||
0 =
Effective ADC resolution is 13 bits (the LSB of a 14-bit output is
OVR) (default) 1 = ADC resolution is 14 bits |
|||
Bit 3 | SEL OVR: OVR selection | ||
0 =
Fast OVR selected (default) 1 = Normal OVR selected. See the Section 8.3.1 section for details. |
|||
Bit 2 | GLOBAL POWER DOWN | ||
0 =
Normal operation (default) 1 = Global power down. All ADC channels, internal references, and output buffers are powered down. Wakeup time from this mode is slow (100 µs). |
|||
Bit 1 | Always write 0 | ||
Bit 0 | CONFIG PDN PIN | ||
Use
this bit to configure PDN terminal. 0 = The PDN terminal functions as a standby terminal. All channels are put in standby. Wake-up time from standby mode is fast (10 µs). (default) 1 = The PDN terminal functions as a global power-down terminal. All ADC channels, internal references, and output buffers are powered down. Wake-up time from global power mode is slow (100 µs). |
