ADVANCE INFORMATION for pre-production products; subject to change without notice.
The THS4561 fully differential amplifier (FDA) offers a simple 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 ultra-low harmonic distortion, the device is well suited for data acquisition systems where high precision is required with the best signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR) through the amplifier and ADC combination.
The THS4561 features the required negative rail input 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-bit to 20-bit successive approximation register (SAR) input requirements. A 2.85-V to 12.6-V supply range with a flexible output common-mode setting with low headroom to the supplies supports a wide range of ADC input and digital-to-analog converter (DAC) output requirements.
The THS4561 will be available in a dual-channel device as the THS4562 in a VQFN-24 package.
