AS1506
Datasheet - Application Information
9 Application Information
The AS1506 is intended for circuits requiring digitally controlled adjustable resistance, such as LCD contrast control
(where voltage biasing adjusts the display contrast), or programmable filters with adjustable gain and/or cutoff fre-
quency.
Programmable Filter
Figure 24
shows the configuration for a 1st-order programmable filter.
The DC gain of the filter is adjusted by R
2
and can be calculated as:
G = 1 + (R

/R

)
(EQ 1)
The cutoff frequency (f
C
) is adjusted by R
3
, and can be calculated as:
f
C
= 1/(2

Offset Voltage and Gain Adjustment
Connect the AS1506 to an op amp to nullify the offset voltage over the operating temperature range. Install another
AS1506 potentiometer in the feedback path to adjust the gain of the op amp (
Figure 25
).
