5 Device Comparison Table
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 amplifiers is characterized for operation over
the full industrial temperature range from –40°C to +85°C. Table 1 shows a comparison of the THS4521 device
to similar TI devices.
