Introduction

AI Translation

The THS4521 is an ultra-low power, fully differential amplifier featuring rail-to-rail output and an input common-mode range that includes the negative supply rail. This amplifier is designed for low-power data acquisition systems and high-density applications where power dissipation is a critical parameter, and also delivers excellent performance in audio applications.

The THS4521 provides precise output common-mode control, enabling DC coupling when driving ADCs. This control capability, combined with an input common-mode range that extends below the negative supply rail and rail-to-rail output, allows straightforward interfacing between single-ended ground-referenced signal sources. In addition, the device is well suited for driving SAR and delta-sigma (ΔΣ) ADCs using only a single 2.5-V to 3.3-V supply and ground.

The THS4521 is characterized for operation over a temperature range of -55°C to 210°C.
