APPLICATIONS

DESCRIPTION

The THS1040 is a CMOS, low power, 10-bit, 40-MSPS

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

single 3-V supply. The THS1040 has been designed to

give circuit developers flexibility. The analog input to the

THS1040 can be either single-ended or differential. The

THS1040 provides a wide selection of voltage

references to match the user’s design requirements.

For more design flexibility, the internal reference can be

bypassed to use an external reference to suit the dc

accuracy and temperature drift requirements of the

application. The out-of-range output indicates any

out-of-range condition in THS1040’s input signal.

The speed, resolution, and single-supply operation of

the THS1040 are suited to applications in set-top-box

(STB),

video,

multimedia,

imaging,

high-speed

acquisition, and communications. The speed and

resolution ideally suit charge-couple device (CCD) input

systems such as color scanners, digital copiers, digital

cameras, and camcorders. A wide input voltage range

allows the THS1040 to be applied in both imaging and

communications systems.

The THS1040C is characterized for operation from 0

°C

to 70

°C, while the THS1040I is characterized for

operation from −40

°C to 85°C.
