The THS4552 fully differential amplifier offers an easy interface from single-ended
sources 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 is
well suited for data acquisition systems where high precision is required along with the best
signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR) through the amplifier and ADC
The THS4552 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 and
drift terms support the emerging 16- to 20-bit successive-approximation register (SAR) input
requirements. A wide-range output common-mode control supports the ADC running from 1.8-V to 5-V
supplies with ADC common-mode input requirements from 0.7 V to greater than
The THS4552 device is characterized for operation over the wide temperature range of
–40°C to +125°C, and is available in 16-pin TSSOP and 24-pin VQFN packages.
