3 Description

The ADC14X250 device is a monolithic single-

channel high performance analog-to-digital converter

capable of converting analog input signals into 14-bit

digital words with a sampling rate of 250 MSPS. This

converter uses a differential pipelined architecture

with integrated input buffer to provide excellent

dynamic performance and low power consumption

across an extended temperature range from –40°C to

105°C as measured at the device's PCB footprint

thermal pad.

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. The buffer can be also be

adjusted

to

correct

for

phase

and

amplitude

imbalance of the differential input signal path to

improve even order harmonic distortion. An input

sampling clock divider provides integer divide ratios

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 single lane interface from a 32-pin, 5-mm × 5-mm

WQFN package. The ADC14X250 operates on 1.2 V,

1.8 V and 3.0 V power supplies. A SPI is available to

configure the device that is compatible with 1.2-V to

3-V logic.
