Texas Instruments THS4541IRGTT
The THS4541 is a low-power, voltage-feedback, fully differential amplifier (FDA) with an input common-mode range below the negative rail, and rail-to-rail output. Designed for low-power data acquisition systems where high density is critical in a high-performance analog-to-digital converter (ADC) or digital-to-analog converter (DAC) interface design.
The THS4541 features the negative-rail input required when interfacing a dc-coupled, ground-centered, source signal. This negative-rail input, with rail-to-rail output, allows for easy interface between single-ended, ground-referenced, bipolar signal sources and a wide variety of SAR, ΔΣ, or pipeline ADCs using only a single +2.7-V to +5.4-V power supply.
The THS4541 is characterized for operation over the wide temperature range of –40°C to 125°C available in 16-pin VQFN and 10-pin WQFN packages.
