32-Channel Inﬁnite

Sample-and-Hold

AD5533*

GENERAL DESCRIPTION

FEATURES

The AD5533 combines a 32-channel voltage translation function

with an inﬁnite output hold capability. An analog input voltage

on the common input pin, V_IN, is sampled and its digital repre-

sentation transferred to a chosen DAC register. V_OUTfor this

DAC is then updated to reflect the new contents of the DAC

inputs A0–A4 or via the serial input port. 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 V_SS+ 2 V to V_DD– 2 V because of the headroom of the

output ampliﬁer.

Inﬁnite Sample-and-Hold Capability to ؎0.018% Accuracy

High Integration: 32-Channel SHA in 12

12 mm²LFBGA

Per Channel Acquisition Time of 16 ␮s max

Adjustable Voltage Output Range

Output Voltage Span 10 V

Output Impedance 0.5 ⍀

Readback Capability

DSP-/Microcontroller-Compatible Serial Interface

Parallel Interface

Temperature Range –40؇C to +85؇C

Data Acquisition

The device is operated with AV_CC= 5 V 5%, DV_CC= 2.7 V to

5.25 V, V_SS= –4.75 V to –16.5 V and V_DD= 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. Inﬁnite Droopless Sample-and-Hold Capability.

Low Cost I/O

2. The AD5533 is available in a 74-lead LFBGA package with a

body size of 12 mm × 12 mm.
