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.
