ADA4411-3

APPLICATIONS

OVERVIEW

CUTOFF FREQUENCY SELECTION

With its high impedance multiplexed inputs and high output

drive, the ADA4411-3 is ideally suited to video reconstruction

and antialias filtering applications. The high impedance inputs

give designers flexibility with regard to how the input signals

are terminated. Devices with DAC current source outputs that

feed the ADA4411-3 can be loaded in whatever resistance

provides the best performance, and devices with voltage outputs

can be optimally terminated as well. The ADA4411-3 outputs

can each drive up to two source-terminated 75 Ω loads and can

therefore directly drive the outputs from set-top boxes, DVD

players, and the like without the need for a separate output

buffer.

Four combinations of cutoff frequencies are provided for the

video signals. The cutoff frequencies have been selected to

correspond with the most commonly deployed component

video scanning systems. Selection between the cutoff frequency

combinations is controlled by the logic signals applied to the

F_SEL_A and F_SEL_B inputs. Table 7 summarizes cutoff

frequency selection.

Binary control inputs are provided to select cutoff frequency,

throughput gain, and input signal. These inputs are compatible

with 3 V and 5 V TTL and CMOS logic levels referenced to

GND. The disable feature is asserted by pulling the DISABLE

pin to the positive supply.

OUTPUT DC OFFSET CONTROL

The LEVEL1 and LEVEL2 inputs work as a differential, input-

referred output offset control. In other words, the output offset

voltage of a given channel is equal to the difference in voltage

between the LEVEL1 and LEVEL2 inputs, multiplied by the

overall filter gain. This relationship is expressed in Equation 1.

The LEVEL1 and LEVEL2 inputs comprise a differential input

that controls the dc level at the output pins.

MULTIPLEXER SELECT INPUTS

V_OS(OUT) = (LEVEL1− LEVEL2)(G)

(1)

Selection between the two multiplexer inputs is controlled by

the logic signals applied to the MUX inputs. Table 6

summarizes the multiplexer operation.

LEVEL1 and LEVEL2 are the voltages applied to the respective

inputs, and G is the throughput gain.

For example, with the G_SEL input set for ×2 gain, setting

LEVEL1 to 3ꢀꢀ mV and LEVEL2 to ꢀ V shifts the offset voltages

at the ADA4411-3 outputs to 6ꢀꢀ mV. This particular setting

can be used in most single-supply applications to keep the

output swings safely above the negative supply rail.

THROUGHPUT GAIN

The throughput gain of the ADA4411-3 signal paths can

be either × 2 or × 4. Gain selection is controlled by the logic

signal applied to the G_SEL pin. Table 6 summarizes how the

gain is selected.

The maximum differential voltage that can be applied across the

LEVEL1 and LEVEL2 inputs is 5ꢀꢀ mV. From a single-ended

standpoint, the LEVEL1 and LEVEL2 inputs have the same

range as the filter inputs. See the Specifications tables for the

limits. The LEVEL1 and LEVEL2 inputs must each be bypassed

to GND with a ꢀ.1 μF ceramic capacitor.

DISABLE

The ADA4411-3 includes a disable feature that can be used

to save power when a particular device is not in use. As

indicated in the Overview section, the disable feature is

asserted by pulling the DISABLE pin to the positive supply.

Table 6 summarizes the disable feature operation. The

DISABLE pin also functions as a reference level for the logic

inputs and therefore must be connected to ground when the

device is not disabled.

In single-supply applications, a positive output offset must be

applied to keep the negative-most excursions of the output

signals above the specified minimum output swing limit.
