The ADC12DS105 is a high-performance CMOS analog-todigital
converter capable of converting two analog input signals
into 12-bit digital words at rates up to 105 Mega Samples
Per Second (MSPS). The digital outputs are serialized and
provided on differential LVDS signal pairs. This converter uses
a differential, pipelined architecture with digital error correction
and an on-chip sample-and-hold circuit to minimize
power consumption and the external component count, while
providing excellent dynamic performance. The ADC12DS105
may be operated from a single +3.0V or 3.3V power supply.
A power-down feature reduces the power consumption to
very low levels while still allowing fast wake-up time to full
operation. The differential inputs accept a 2V full scale differential
input swing. A stable 1.2V internal voltage reference is
provided, or the ADC12DS105 can be operated with an external
1.2V reference. The selectable duty cycle stabilizer
maintains performance over a wide range of clock duty cycles.
A serial interface allows access to the internal registers
for full control of the ADC12DS105's functionality. The ADC12DS105
is available in a 60-lead LLP package and operates
over the industrial temperature range of ?40°C to +85°C
