The THS4561 fully differential amplifier (FDA) offers a simple interface fromsingle-ended sources to the differential output required by precision analog-to-digital converters(ADCs). Designed for a very low, 8-Hz, 1/f voltage noise corner and low, 130-dB total harmonicdistortion (THD) while consuming on a 775-µA quiescent current, the THS4561 is well suited forpower-sensitive data acquisition (DAQ) systems where high performance is required with the bestsignal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR) through the amplifier and ADCcombination.

The THS4561 features the required negative rail input when interfacing a dc-coupled,ground-centered, source signal to a single-supply, differential-input ADC. Low dc error and driftterms support the emerging high-speed and high-resolution successive approximation register (SAR)and delta-sigma (ΔΣ) ADC input requirements. A 2.85-V to 12.6-V supply range with a flexible outputcommon-mode setting with low headroom to the supplies supports a wide range of ADC input anddigital-to-analog converter (DAC) output requirements.

The THS4561 device is characterized for operation from –40°C to +125°C.
