The ADC14C105 is a high-performance CMOS analog-to-digital converter capable of
converting analog input signals into 14-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 sample-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 ADC14C105 may be operated from a single +3.0V or +3.3V
power supply and consumes low power.
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 differential input swing. A stable 1.2V internal voltage reference is provided, or
the ADC14C105 can be operated with an external 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.
The ADC14C105 is available in a 32-lead WQFN package and operates over the industrial
temperature range of −40°C to +85°C.
