3 Description
The ADC16DX370 device 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 370 MSPS. 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, 8-
mm × 8-mm WQFN package. A SPI is available to
configure the device that is compatible with 1.2-V to
3-V logic.
