APPLICATIO S I FOR ATIO
WU
UU
The difference amplifier generates the high and low refer-
ence for the ADC. High speed switching circuits are
connected to these outputs and they must be externally
bypassed. Each output has two pins. The multiple output
pins are needed to reduce package inductance. Bypass
capacitors must be connected as shown in Figure 6. Each
ADC channel has an independent reference with its own
bypass capacitors. The two channels can be used with the
same or different input ranges.
Other voltage ranges between the pin selectable ranges
can be programmed with two external resistors as shown
in Figure 7. An external reference can be used by applying
its output directly or through a resistor divider to SENSE.
It is not recommended to drive the SENSE pin with a logic
device. The SENSE pin should be tied to the appropriate
level as close to the converter as possible. If the SENSE pin
is driven externally, it should be bypassed to ground as
close to the device as possible with a 1
F ceramic capacitor.
For the best channel matching, connect an external reference
to SENSEA and SENSEB.

Driving the Clock Input
The CLK inputs can be driven directly with a CMOS or TTL
level signal. A differential clock can also be used along with
a low jitter CMOS converter before the CLK pin (Figure 8).
Figure 8. CLK Drive Using an LVDS or PECL to CMOS Converter
The noise performance of the LTC2290 can depend on the
clock signal quality as much as on the analog input. Any
noise present on the clock signal will result in additional
aperture jitter that will be RMS summed with the inherent
ADC aperture jitter.
It is recommended that CLKA and CLKB are shorted
together and driven by the same clock source. If a small
time delay is desired between when the two channels
sample the analog inputs, CLKA and CLKB can be driven
by two different signals. If this delay exceeds 1ns, the
performance of the part may degrade. CLKA and CLKB
should not be driven by asynchronous signals.
Input Range
The input range can be set based on the application. The
2V input range will provide the best signal-to-noise perfor-
mance while maintaining excellent SFDR. The 1V input
range will have better SFDR performance, but the SNR will
degrade by 3.8dB.
