The THS4521ID is a very low power rail-to-rail output fully Differential Amplifier with an input common-mode range that includes the negative rail. This amplifier is 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. This fully differential amplifier feature accurate output common-mode control that allows for dc-coupling when driving analogue-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, this device is 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.
