Texas Instruments THS4551IRUNR
The THS4551 fully differential amplifier offers an easy interface from single-endedsources to the differential output required by high-precision analog-to-digital converters (ADCs).Designed for exceptional dc accuracy, low noise, and robust capacitive load driving, this device iswell suited for data acquisition systems where high precision is required along with the bestsignal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR) through the amplifier and ADCcombination.
The THS4551 features the negative rail input required when interfacing a dc-coupled,ground-centered, source signal to a single-supply differential input ADC. Very low dc error anddrift terms support the emerging 16- to 20-bit successive-approximation register (SAR) inputrequirements. A wide-range output common-mode control supports the ADC running from 1.8-V to 5-Vsupplies with ADC common-mode input requirements from 0.7 V to greater than3.0 V.
The THS4551 device is characterized for operation over the wide temperature range of–40°C to +125°C, and is available in 8-pin VSSOP, 16-pin VQFN, and 10-pin WQFN packages.
