Differential amplifier offers easy interface from single-ended sources to differential output

Texas Instruments THS4551 fully differential amplifier, available from Mouser, offers an easy interface from single-ended sources to the differential output required by high-precision analog-to-digital converters (ADCs). These are designed for exceptional DC accuracy, low noise and robust capacitive load driving. This makes them well suited for data acquisition systems where high precision is required along with the best signal-to-noise ratio and spurious-free dynamic range (SFDR) through the amplifier and ADC combination. The device features the negative rail input required when interfacing a DC-coupled, ground-centred, 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) input requirements. A wide-range output common-mode control supports the ADC running from 1.8V to 5V supplies with ADC common-mode input requirements from 0.7V to greater than 3V.
