APPLICATIONS

DESCRIPTION

The THS1009 is a CMOS, low-power, 10-bit, 8 MSPS

analog-to-digital

converter

(ADC).

The

speed,

resolution, bandwidth, and single-supply operation are

suited for applications in radar, imaging, high-speed

acquisition,

and

communications.

A

multistage

pipelined architecture with output error correction logic

provides for no missing codes over the full operating

temperature range. Internal control registers allow for

programming the ADC into the desired mode. The

THS1009 consists of two analog inputs, which are

sampled simultaneously. These inputs can be selected

individually

and

configured

to

single-ended

or

differential inputs. Internal reference voltages for the

ADC (1.5 V and 3.5 V) are provided. An external

reference can also be chosen to suit the dc accuracy

and temperature drift requirements of the application.

The THS1009C is characterized for operation from 0

°C

to 70

°C, and the THS1009I is characterized for

operation from –40

°C to 85°C.
