BIAS ADJUSTMENT CIRCUIT BLOCK
A.C. OPERATING CHARACTERISTICS
Recommended Operating Conditions: (Vcc, V+ = 4.75 to 5.25V; Vsense+, Vsense- = 26V; T
A
= -40°C to +85°C, unless
otherwise noted.)
A.C. TIMING
Note:
(11) MI in the A.C. timing diagram refers to the minimum incremental change in the V
BIAS
output due to a change in the wiper position.
