DESCRIPTION

The THS1206 is a CMOS, low-power, 12-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 THS1206 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 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 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 THS1206.

The internal clock oscillator is switched off in continuous

conversion mode.

The THS1206C is characterized for operation from 0°C to

70°C while the THS1206I is characterized for operation

from –40°C to 85°C. The THS1206Q is characterized to

meet the rigorous requirements of the automotive

environment from –40°C to 125°C. The THS1206M is

characterized for operation over the full military

temperature range of –55°C to 125°C.
