Automotive High-Speed Differential I/O Amplifier

The THS4541-Q1 is a

low-power, voltage-feedback, fully differential amplifier

(FDA) with an input common-mode range less than 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-Q1

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 an

easy interface between single-ended, ground-referenced,

bipolar signal sources and a wide variety of successive

approximation register (SAR), delta-sigma (ΔΣ), or pipeline

ADCs using only a single 2.7V to 5.4V power supply.

The THS4541-Q1 is

characterized for operation over the wide temperature range

of –40°C to +125°C and is available in a 16-pin VQFN

package, both with and without wettable flanks. The package

with wettable flanks eases post-assembly visual inspection

and is available as the THS4541W-Q1.
