THS4524-EP - Enhanced Product very low power quad channel rail-to-rail output fully differential amplifier

The THS4524 is a very low-power, fully differential operational 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 systems and high-density applications where power dissipation is a critical parameter, and provide exceptional performance in audio applications.

This fully differential op amp 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, the THS4524 is ideally suited for driving both successive-approximation register (SAR) and delta-sigma (ΔΣ) ADCs using only a single +2.5-V to +5-V and ground power supply.

The THS4524 fully differential op amp is characterized for operation over the full industrial temperature range from –55°C to 125°C.
