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 鈥?.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
V
SS
+ 2 V to V
DD
鈥?2 V because of the headroom of the out-
put amplifier.
The device is operated with AV

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.
