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. Low-Power ADCs Supported by the THS4552 PART NUMBER ADC TYPE RESOLUTION, SPEED ADS1278 Delta sigma Octal, 24 bits, 0.512 MSPS ADS8694 SAR Quad, 18 bits, 0.5 MSPS ADC3221 Pipeline Dual, 12 bits, 25 MSPS ADC3241 Pipeline Dual, 14 bits, 25 MSPS (1) For all available packages, see the orderable addendum at the end of the datasheet.
