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
VSS + 2 V to VDD – 2 V because of the headroom of the out-
put amplifier.
The device is operated with AVCC = 5 V ± 5%, DVCC = 2.7 V
to 5.25 V, VSS = –4.75 V to –12 V and VDD = +4.75 V to +12 V
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.
