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.
