ADS5474

SLAS525C – JULY 2007 – REVISED JANUARY 2016

ADS5474 14-Bit, 400-MSPS Analog-to-Digital Converter

1 Features

3 Description

The ADS5474 device is a 14-bit, 400-MSPS analog-

1

•

400-MSPS Sample Rate

to-digital converter (ADC) that operates from both a

•

14-Bit Resolution, 11.2-Bits ENOB

5-V supply and 3.3-V supply while providing LVDS-

•

1.4-GHz Input Bandwidth

compatible digital outputs. This ADC is one of a

family of 12-, 13-, and 14-bit ADCs that operate from

•

80-dBc SFDR at 230 MHz and 400 MSPS

210 MSPS to 500 MSPS. The ADS5474 device has

•

69.8-dBFS SNR at 230 MHz and 400 MSPS

an input buffer that isolates the internal switching of

•

the onboard track and hold (T&H) from disturbing the

signal source while providing a high-impedance input.

•

LVDS-Compatible Outputs

An internal reference generator is also provided to

•

2.5-W Total Power Dissipation

simplify the system design.

•

50-mW Power Down Mode

Designed with a 1.4-GHz input bandwidth for the

•

Offset Binary Output Format

conversion of wide-bandwidth signals that exceed

•

Output Data Transitions on the Rising and Falling

400 MHz of input frequency at 400 MSPS, the

Edges of a Half-Rate Output Clock

ADS5474

device

has

outstanding

low-noise

performance and spurious-free dynamic range over a

•

On-Chip Analog Buffer, Track-and-Hold, and

large input frequency range.
