OPAxEN OPAxSP — — — — OPAxCH<1:0>
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared q = Value depends on condition
bit 7
OPAxEN: Op Amp Enable bit
1 = Op amp is enabled
0 = Op amp is disabled and consumes no active power
bit 6
OPAxSP: Op Amp Speed/Power Select bit
1 = Comparator operates in high GBWP mode
0 = Comparator operates in low GBWP mode
bit 5-2
Unimplemented: Read as ‘0’
bit 1-0 OPAxCH<1:0>: Non-inverting Channel Selection bits
11 = Non-inverting input connects to FVR Buffer 2 output
10 = Non-inverting input connects to DAC_output
0x = Non-inverting input connects to OPAxIN+ pin
