SLAS284A 鈥?AUGUST 2000 鈥?REVISED DECEMBER 2002
12 BIT 4 ANALOG INPUT, 6 MSPS, SIMULTANEOUS SAMPLING
ANALOG TO DIGITAL CONVERTER
FEATURES
D
Simultaneous Sampling of 4 Single-Ended
Signals or 2 Differential Signals or
Combination of Both
to program the ADC into the desired mode. The
THS1207 consists of four analog inputs, which are
sampled simultaneously. These inputs can be selected
individually and configured to single-ended or
differential-inputs. 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.
The THS1207C is characterized for operation from 0擄C
to 70擄C, the THS1207I is characterized for operation
from 鈥?0擄C to 85擄C.

DESCRIPTION
The THS1207 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
