ADC Single SAR 1Msps 16-bit Parallel 48-Pin VQFN EP T/R, ADS8472IBRGZTG4, Texas Instruments

The ADS8472 is an 16-bit, 1-MSPS A/C converter with an internal 4.096-V reference and a pseudo-bipolar, fully differential input. The device includes a 16-bit capacitor-based SAR A/D converter with inherent sample and hold. The ADS8472 offers a full 16-bit interface or an 8-bit bus option using two read cycles. The ADS8472 is available in a 48-lead 7×7 QFN package and is characterized over the industrial -40°C to 85°C temperature range.
