The THS4521, THS4522, and THS4524
family of devices are very low-power, fully differential amplifiers 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 FDA (THS4521), dual FDA (THS4522), and quad FDA (THS4524)
These fully differential amplifiers 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
characterized for operation over the full industrial temperature range
from 40°C to +85°C.
