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
communications.
A
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.
acquisition,
multistage
and
pipelined
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
