32-Channel, 14-Bit DAC with Precision  
Infinite Sample-and-Hold Mode  
a
AD5532B*  
GENERAL DESCRIPTION  
FEATURES  
The AD5532B is a 32-channel, voltage output, 14-bit DAC with  
an additional precision infinite sample-and-hold mode. The  
selected DAC register is written to via the 3-wire serial inter-  
face and VOUT for this DAC is then updated to reflect the new  
contents of the DAC register. DAC selection is accomplished via  
address bits A0–A4. The output voltage range is determined by  
the offset voltage at the OFFS_IN pin and the gain of the  
output amplifier. It is restricted to a range from VSS + 2 V to  
VDD – 2 V because of the headroom of the output amplifier.  
High Integration:  
32-Channel DAC in 12 mm ꢀ 12 mm CSPBGA  
Guaranteed Monotonic to 14 Bits  
Infinite Sample-and-Hold Capability to ꢁ0.018% Accuracy  
Infinite Sample-and-Hold Total Unadjusted Error ꢁ2.5 mV  
Adjustable Voltage Output Range  
Readback Capability  
DSP/Microcontroller Compatible Serial Interface  
Output Impedance 0.5 ꢂ  
Output Voltage Span 10 V  
Temperature Range –40ꢃC to +85ꢃC  
The device is operated with AVCC = +5 V 5%, DVCC = +2.7 V  
to +5.25 V, VSS = –4.75 V to –16.5 V, and VDD = +8 V to +16.5 V  
and requires a stable 3 V reference on REF_IN as well as an  
offset voltage on OFFS_IN.  
APPLICATIONS  
Automatic Test Equipment  
Optical Networks  
Level Setting  
PRODUCT HIGHLIGHTS  
1. 32-channel, 14-bit DAC in one package, guaranteed  
monotonic.  
Instrumentation  
Industrial Control Systems  
Data Acquisition  
Low Cost I/O  
2. The AD5532B is available in a 74-lead CSPBGA with a body  
size of 12 mm ꢀ12 mm.  
3. In infinite sample-and-hold mode, a total unadjusted error of  
2.5 mV is achieved by laser-trimming on-chip resistors.
