5 ⍀ Output Voltage Span 10 V Temperature Range –40 ؇C to +85؇ C APPLICATIONS Automatic Test Equipment Optical Networks Level Setting Instrumentation Industrial Control Systems Data Acquisition Low Cost I/O 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 interface 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.
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.
PRODUCT HIGHLIGHTS 1.
32-channel, 14-bit DAC in one package, guaranteed monotonic.
2.
The AD5532B is available in a 74-lead CSPBGA with a body size of 12 mm ϫ 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.
