G2-G0 (Gain Bits) [29:27] [13:11]
For VRS = 0, A = 2; For VRS = 1, A = 1; Bipolar input span is twice the unipolar input span.
000
Gain = 1, (Input Span = [(VREF+)-(VREF-)]/1*A for unipolar).
001
Gain = 2, (Input Span = [(VREF+)-(VREF-)]/2*A for unipolar).
010
Gain = 4, (Input Span = [(VREF+)-(VREF-)]/4*A for unipolar).
011
Gain = 8, (Input Span = [(VREF+)-(VREF-)]/8*A for unipolar).
100
Gain = 16, (Input Span = [(VREF+)-(VREF-)]/16*A for unipolar).
101
Gain = 32, (Input Span = [(VREF+)-(VREF-)]/32*A for unipolar).
110
Gain = 64, (Input Span = [(VREF+)-(VREF-)]/64*A for unipolar).
WR3-WR0 (Word Rate) [26:23] [10:7]
The listed Word Rates are for continuous conversion mode using a 4.9152 MHz clock. All word rates will
scale linearly with the clock frequency used. The very first conversion using continuous conversion mode
will last longer, as will conversions done with the single conversion mode. See the section on Performing
Conversions and Tables 1 and 2 for more details.
