ADS61B23 Analog-to-Digital Converters

ADS61B23 is a 12-bit A/D converter (ADC) with a maximum sampling frequency of 80 MSPS. It combines high performance and low power consumption in a compact 32-QFN package. The analog inputs use buffers to isolate the switching transients of the internal sample & hold from the external driving circuit. The buffered inputs present very low input capacitance (< .
