Features 1 GHz Full Power Bandwidth Internal reference and sample-and-hold circuit Low power consumption Data Ready output clock Clock Duty Cycle Stabilizer Single +3.0V or +3.3V supply operation Power-down mode 32-pin LLP package, (5x5x0.8mm, 0.5mm pin-pitch) Description 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 LLP package and operates over the industrial temperature range of −40°C to +85°C.
