Overview
The THS4524MDBTREP is a very low-power, fully differential operational amplifier produced by Texas Instruments. This amplifier is designed for low-power data acquisition systems and high-density applications where power dissipation is a critical parameter. It features rail-to-rail output and an input common-mode range that includes the negative rail, making it ideal for interfacing between single-ended, ground-referenced signal sources. The THS4524 is characterized for operation over the full industrial temperature range from –55°C to 125°C, making it suitable for a wide range of applications, including low-power SAR and ΔΣ ADC drivers, differential signal conditioning, and high-performance differential audio amplifiers.
