ADC12C105  
12-Bit, 95/105 MSPS A/D Converter  
General Description  
Features  
The ADC12C105 is a high-performance CMOS analog-to-  
digital converter capable of converting analog input signals  
into 12-bit digital words at rates up to 105 Mega Samples Per  
Second (MSPS). This converter uses a differential, pipelined  
architecture with digital error correction and an on-chip sam-  
ple-and-hold circuit to minimize power consumption and the  
external component count, while providing excellent dynamic  
performance. A unique sample-and-hold stage yields a full-  
power bandwidth of 1 GHz. The ADC12C105 may be oper-  
ated from a single +3.0V or +3.3V power supply and  
consumes low power.

Power-down mode  
32-pin LLP package, (5x5x0.8mm, 0.5mm pin-pitch)  
Key Specifications  
A separate +2.5V supply may be used for the digital output  
interface which allows lower power operation with reduced  
noise. 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 differ-  
ential input swing. A stable 1.2V internal voltage reference is  
provided, or the ADC12C105 can be operated with an exter-  
nal 1.2V reference. Output data format (offset binary versus  
2's complement) and duty cycle stabilizer are pin-selectable.  
The duty cycle stabilizer maintains performance over a wide  
range of clock duty cycles.
