DESCRIPTION
The THS10064 is a CMOS, low-power, 10-bit, 6 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 are used to program the ADC into the desired
mode. The THS10064 consists of four 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 improve data transfers to the
processor. 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 single conversion mode, a single and
simultaneous conversion of up to four inputs can be
initiated by using the single conversion start signal
(CONVST). The conversion clock in single conversion
mode is generated internally using a clock oscillator
circuit. In continuous conversion mode, an external clock
signal is applied to the CONV_CLK input of the
THS10064. The internal clock oscillator is switched off in
continuous conversion mode.
The THS10064C is characterized for operation from 0°C
to 70°C, and the THS10064I is characterized for operation
from –40°C to 85°C.
