DESCRIPTION

The ADC12QS065 is a low power, high performance

CMOS 4-channel analog-to-digital converter with

LVDS serialized outputs. The ADC12QS065 digitizes

signals to 12 bits resolution at sampling rates up to

65 MSPS while consuming a typical 200 mW/ADC

from a single 3.3V supply. Sampled data is

transformed into high speed serial LVDS output data

streams. Clock and frame LVDS pairs aid in data

capture. The ADC12QS065’s six differential pairs

transmit data over backplanes or cable and also

make PCB design easier. In addition, the reduced

cable, PCB trace count, and connector size

tremendously reduce cost.

No missing codes performance is ensured over the

full operating temperature range. The pipeline ADC

architecture achieves 11 Effective Bits over the entire

Nyquist band at 65 MSPS.

When not converting, power consumption can be

reduced by pulling the PD (Power Down) pin high,

placing the converter into a low power state where it

typically consumes less than 3 mW total, and from

which recovery is less than 5 ms. The

ADC12QS065's speed, resolution and single supply

operation makes it well suited for a variety of

applications in ultrasound, imaging, video and

communications. Operating over the industrial (-40°C

to +85°C) temperature range, the ADC12QS065 is

available in a 60-pin WQFN package with exposed

pad (9x9x0.8mm, 0.5mm pin pitch).
