AD584
NOISE FILTERING
The bandwidth of the output amplifier in the AD584 can be
reduced to filter output noise. A capacitor ranging between 0.01 μF
and 0.1 μF connected between the CAP and V BG terminals further
reduces the wideband and feedthrough noise in the output of
the AD584 , as shown in Figure 9 and Figure 10. However, this
tends to increase the turn-on settling time of the device; therefore,
allow for ample warm-up time.

Data Sheet
USING THE STROBE TERMINAL
The AD584 has a strobe input that can be used to zero the output.
This unique feature permits a variety of new applications in
signal and power conditioning circuits.
can be used to translate a TTL logic signal into a strobe of the
output. The AD584 operates normally when there is no current
drawn from Pin 5. Bringing this terminal low, to less than 200 mV,
allows the output voltage to go to zero. In this mode, the AD584

is not required to source or sink current (unless a 0.7 V residual
output is permissible). If the AD584 is required to sink a transient
current while strobe is off, limit the strobe terminal input current

SPECIFIED FREQUENCY
The strobe terminal tolerates up to 5 μA leakage, and its driver
should be capable of sinking 500 μA continuous. A low leakage,
open collector gate can be used to drive the strobe terminal directly,
provided the gate can withstand the AD584 output voltage plus 1 V.
PERCISION HIGH CURRENT SUPPLY
The AD584 can be easily connected to a power PNP or power
PNP Darlington device to provide much greater output current

capability. The circuit shown in Figure 12 delivers a precision
10 V output with up to 4 A supplied to the load. If the load has a
significant capacitive component, the 0.1 μF capacitor is required.
If the load is purely resistive, improved high frequency, supply
rejection results from removing the capacitor.
