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 V
outputs.

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.
