GENERAL DESCRIPTION

The AD5533B combines a 32-channel voltage translation function

with an infinite output hold capability. An analog input voltage on

the common input pin, V

, is sampled and its digital represen-

tation transferred to a chosen DAC register. V

OUT

for this DAC

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

Channel selection is accomplished via the parallel address 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

+ 2 V

to V

– 2 V because of the headroom of the output amplifier.

The device is operated with AV

= +5 V

5%, DV

= +2.7 V

to +5.25 V, V

= –4.75 V to –16.5 V, and V

= +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. Precision infinite droopless sample-and-hold capability.

2. The AD5533B 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.
