ADS5237

SBAS420A – AUGUST 2007 – REVISED OCTOBER 2007

Dual, 10-Bit, 65MSPS, +3.3V

Analog-to-Digital Converter

• Single +3.3V Supply

• High SNR: 61.7dBFS at f

The ADS5237 is a dual, high-speed, high dynamic

range, 10-bit, pipelined analog-to-digital converter

• Total Power Dissipation:

(ADC).

This

device

includes

a

high-bandwidth

Internal Reference: 366mW

sample-and-hold

amplifier

that

gives

excellent

External Reference: 330mW

spurious performance up to and beyond the Nyquist

• Internal or External Reference

rate. The differential nature of the sample-and-hold

amplifier and ADC circuitry minimizes even-order

• Low DNL: ±0.1LSB

harmonics and gives excellent common-mode noise

• Flexible Input Range: 1.5V

immunity.

• TQFP-64 Package

The ADS5237 provides for setting the full-scale range

of the converter without any external reference

circuitry. The internal reference can be disabled,

• Communications IF Processing

allowing low-drive, external references to be used for

• Communications Base Stations

improved tracking in multichannel systems.

• Test Equipment

The ADS5237 provides an over-range indicator flag

• Medical Imaging

to indicate an input signal that exceeds the full-scale

• Video Digitizing

input range of the converter. This flag can be used to

reduce the gain of front-end gain control circuitry.

• CCD Digitizing

There is also an output enable pin to allow for

multiplexing and testing on a printed circuit board

(PCB).

The

ADS5237

employs

digital

error

correction

techniques to provide excellent differential linearity for

demanding imaging applications. The ADS5237 is

available in a TQFP-64 package.
