Dual Channel, Low-Noise, Precision, 150-MHz, Fully Differential Amplifier

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

combination.

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 3.0 V.

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.
