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.
