FUNCTIONAL DESCRIPTION
The AD5533 can be thought of as consisting of an ADC and
32 DACs in a single package. The input voltage VIN is sampled
and converted into a digital word. The digital result is loaded
into one of the DAC Registers and is converted (with gain and
offset) into an analog output voltage (VOUT0–VOUT31). Since
the channel output voltage is effectively the output of a DAC,
there is no droop associated with it. As long as power to the
device is maintained, the output voltage will remain constant
until this channel is addressed again.
To update a single channel’s output voltage, the required new
voltage level is set up on the Common Input Pin, VIN. The desired
channel is then addressed via the Parallel Port or the Serial Port.
When the channel address has been loaded, provided
TRACK is
high, the circuit begins to acquire the correct code to load to the
DAC in order that the DAC output matches the voltage on VIN.
The
BUSY Pin goes low and remains so until the acquisition is
complete. The noninverting input to the output buffer is tied to VIN
during the acquisition period to avoid spurious outputs, while
the DAC acquires the correct code. The acquisition is completed
in 16
µs max. The BUSY Pin goes high and the updated DAC
output assumes control of the output voltage. The output voltage
of the DAC is connected to the noninverting input of the output
buffer. Since the internal DACs are offset by 70 mV (max) from
GND, the minimum VIN in ISHA Mode is 70 mV. The maximum
VIN is 2.96 V due to the upper dead band of 40 mV (max).
On power-on, all the DACs, including the offset channel, are loaded
with zeros. Each of the 33 DACs is offset internally by 50 mV (typ)
from GND so the outputs VOUT0 to VOUT31 are 50 mV (typ) on
power-on if the OFFS_IN Pin is driven directly by the on-board
offset channel (OFFS_OUT), i.e.: If OFFS_IN = OFFS_OUT =
50 mV = > VOUT = (Gain
× VDAC)– (Gain – 1) × VOFFS_IN = 50 mV.
Analog Input
The equivalent analog input circuit is shown in Figure 6. The
Capacitor C1 is typically 20 pF and can be attributed to the pin
capacitance and 32 off-channels. When a channel is selected, an
extra 7.5 pF (typ) is switched in. This Capacitor C2 is charged to the
previously acquired voltage on that particular channel so it must
charge/discharge to the new level. It is essential that the external
source can charge/discharge this additional capacitance within
1
µs–2 µs of channel selection so that V
IN can be acquired accurately.
For this reason a low impedance source is recommended.

Large source impedances will significantly affect the performance of
the ADC. This may necessitate the use of an input buffer amplifier.
Output Buffer Stage—Gain and Offset
The function of the output buffer stage is to translate the 50 mV–3 V
output of the DAC to a wider range. This is done by gaining up
the DAC output by 3.52 and offsetting the voltage by the voltage
on the OFFS_IN Pin.

VDAC is the output of the DAC.
VOFFS_IN is the voltage at the OFFS_IN Pin.
Table I shows how the output range on VOUT relates to the offset
voltage supplied by the user.

VOUT is limited only by the headroom of the output amplifiers,
VOUT must be within the maximum ratings.
Offset Voltage Channel
The offset voltage can be externally supplied by the user at
OFFS_IN or it can be supplied by an additional offset voltage
channel on the device itself. The required offset voltage is set up
on VIN and acquired by the offset DAC. This offset channel’s
DAC output is directly connected to OFFS_OUT. By connect-
ing OFFS_OUT to OFFS_IN this offset voltage can be used as
the offset voltage for the 32-output amplifiers. It is important to
choose the offset so that VOUT is within maximum ratings.
