The THS4524IDBT is a very low-power fully Differential Amplifier with rail-to-rail output and an input common-mode range that includes the negative rail. This amplifier is designed for low-power data acquisition system and high-density applications where power dissipation is a critical parameter and provides exceptional performance in audio applications. The family includes quad FDA version. This fully differential amplifier features 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 +2.5 to +5V and ground power supply.
