Part Details:

a 32-Channel Precision Infinite Sample-and-Hold AD5533B* FEATURES GENERAL DESCRIPTION Infinite Sample-and-Hold Capability to 0.018% Accuracy The AD5533B combines a 32-channel voltage translation function Infinite Sample-and-Hold Total Unadjusted Error 2.5 m V with an infinite output hold capability. An analog input voltage on High Integration: the common input pin, VIN, is sampled and its digital represen- 32-Channel DAC in 12 mm 12 mm CSPBGA tation transferred to a chosen DAC register. VOUT for this DAC Per Channel Acquisition Time of 16 s Max is then updated to reflect the new contents of the DAC register. Adjustable Voltage Output Range Channel selection is accomplished via the parallel address inputs Output Impedance 0.5 A0­A4 or via the serial input port. The output voltage range is Output Voltage Span 10 V determined by the offset voltage at the OFFS_IN pin and the gain Readback Capability of the output amplifier. It is restricted to a range from VSS + 2 V DSP/Microcontroller Compatible Serial Interface to VDD ­ 2 V because of the headroom of the output amplifier. Parallel Interface The device is operated with AVCC = +5 V ± 5%, DVCC = +2.7 V Temperature Range ­40 C to +85 C to +5.25 V, VSS = ­4.75 V to ­16.5 V, and VDD = +8 V to APPLICATIONS +16.5 V and requires a stable 3 V reference on REF_IN as well Optical Networks as an offset voltage on OFFS_IN. Automatic Test EquipmentLevel Setting PRODUCT HIGHLIGHTS Instrumentation 1. Precision infinite droopless sample-and-hold capability. Industrial Control Systems 2. The AD5533B is available in a 74-lead CSPBGA with a Data Acquisition body size of 12 mm 12 mm. Low Cost I/O 3. In infinite sample-and-hold mode, a total unadjusted error of ±2.5 mV is achieved by laser-trimming on-chip resistors.
