Texas Instruments ADC16DX370 Dual 16-Bit Analog-to-Digital Converter
Texas Instruments ADC16DX370 Dual 16-Bit Analog-to-Digital Converter is a monolithic dual-channel high performance analog-to-digital converter capable of converting analog input signals into 16-bit digital words with a sampling rate of 370MSPS. This converter uses a differential pipelined architecture with integrated input buffer to provide excellent dynamic performance while maintaining low power consumption. The integrated input buffer eliminates charge kickback noise coming from the internal switched capacitor sampling circuits and eases the system-level design of the driving amplifier, anti-aliasing filter, and impedance matching. An input sampling clock divider provides integer divide ratios with configurable phase selection to simplify system clocking. An integrated low-noise voltage reference eases board level design without requiring external decoupling capacitors. The output digital data is provided through a JESD204B subclass 1 interface from a 56-pin, 8mm × 8mm WQFN package. A SPI is available to configure the device that is compatible with 1.2V to 3.0V logic.Features
