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 (< 2pF) &wide bandwidth.This makes it easy to drive them at high input frequencies, compared to an ADC without the input buffers.
The ADS61B23 is a high-performance 12-bit Analog-to-Digital Converter (ADC) featuring a maximum sampling frequency of 80 MSPS. It integrates buffered analog inputs to isolate switching transients, presenting very low input capacitance (< 2 pF) and wide bandwidth for easy driving at high frequencies.
The device offers flexible output options including Parallel CMOS and Double Data Rate (DDR) LVDS interfaces, with programmable gain settings to optimize Signal-to-Noise Ratio (SNR) and Spurious-Free Dynamic Range (SFDR). It includes an internal reference voltage, eliminating the need for external decoupling capacitors in standard configurations.
