GENERAL DESCRIPTION
The AD5532HS is a 32-channel voltage-output 14-bit DAC
with a high-speed serial interface. The selected DAC register is
written to via the 3-wire interface. The serial interface operates
at clock rates up to 30 MHz and is compatible with DSP and
microcontroller interface standards. The output voltage range is
0 V to 5 V or –2.5 V to +2.5 V and is determined by the offset
voltage at the OFFS_IN pin. It is restricted to a range from
+ 2 V to VDD – 2 V because of the headroom of the out-
V
SS
put amplifier.
The device is operated with AV
to 5.25 V, V
= –4.75 V to –12 V and VDD = +4.75 V to +12 V
SS
= 5 V ± 5%, DVCC = 2.7 V
CC
and requires a stable 2.5 V reference on REF_IN.
PRODUCT HIGHLIGHTS
1. 32 14-bit DACs in one package, guaranteed monotonic.
2. The AD5532HS is available in a 74-ball LFBGA package
with a body size of 12 mm by 12 mm.

NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
2
Transient currents of up to 100 mA will not cause SCR latch-up.
3
This limit includes load power and applies only when there is a resistive load on

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD5532HS features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
