The THS4521, THS4522, and THS4524 family of
devices are very low-power, fully differential op amps
with rail-to-rail output and an input common-mode
range that includes the negative rail. These amplifiers
are designed for low-power data acquisition systems
and high-density applications where power
dissipation is a critical parameter, and provide
exceptional performance in audio applications.
The family includes single (THS4521), dual
(THS4522), and quad (THS4524) versions.
These fully differential op amps feature accurate
output common-mode control that allows for
dc-coupling when driving analog-to-digital converters
(ADCs). This control, coupled with an input
common-mode range below the negative rail as well
as rail-to-rail output, allows for easy interfacing
between single-ended, ground-referenced signal
sources. Additionally, these devices are ideally suited
for driving both successive-approximation register
(SAR) and delta-sigma (ΔΣ) ADCs using only a single
+2.5V to +5V and ground power supply.
The THS4521, THS4522, and THS4524 family of fully
differential op amps is characterized for operation
over the full industrial temperature range from –40°C
to +85°C.
