DESCRIPTION
The THS10082 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 THS10082 consists of two analog inputs,
which are sampled simultaneously. These inputs can be
selected individually and configured to single-ended or
differential inputs. An integrated 16 word deep FIFO
allows the storage of data in order to take the load off
of the processor connected to the ADC. 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. Two different conversion modes can be
selected. In the single conversion mode, a single and
simultaneous conversion can be initiated by using the
single conversion start signal (CONVST). The conversion
clock in the single conversion mode is generated internally
using a clock oscillator circuit. In the continuous
conversion mode, an external clock signal is applied to the
CONV_CLK input of the THS10082. The internal clock
oscillator is switched off in the continuous conversion
mode.
The THS10082C is characterized for operation from 0°C
to 70°C, and the THS10082I is characterized for operation
from −40°C to 85°C.
