DESCRIPTION

The ADS824 is a pipeline, CMOS analog-to-digital converter

that operates from a single +5V power supply. This converter

provides excellent performance with a single-ended input and

can be operated with a differential input for added spurious

performance. This high performance converter includes a 10-bit

quantizer, high bandwidth track/hold, and a high accuracy

internal reference. It also allows for the user to disable the

internal reference and utilize external references. This external

reference option provides excellent gain and offset matching

when used in multi-channel applications or in applications

where full scale range adjustment is required.

The ADS824 employs digital error correction techniques to

provide excellent differential linearity for demanding imaging

applications. Its low distortion and high SNR give the extra

margin needed for medical imaging, communications, video,

and test instrumentation. The ADS824 offers power dissipa-

tion of 315mW and also provides a power-down mode, thus

reducing power dissipation to only 20mW.

The ADS824 is specified at a maximum sampling frequency of

70MHz and a single-ended input range of 1.5V to 3.5V. The

ADS824 is available in a 28-lead SSOP package and is pin

compatible with the 10-bit, 40MHz ADS822 and the 10-bit,

60MHz ADS823.
