Description The ADC14155 is a high-performance CMOS analog-to-digital converter capable of converting analog input signals into 14-bit
digital words at rates up to 155 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 1.1
GHz. The ADC14155 operates from dual +3.3V and +1.8V power supplies and consumes 967 mW of power at 155 MSPS.
The separate +1.8V supply for the digital output interface allows lower power operation with reduced noise. A power-down feature
reduces the power consumption to 5 mW with the clock input disabled, while still allowing fast wake-up time to full operation.
The differential inputs provide a full scale differential input swing equal to 2 times the reference voltage. A stable 1.0V
internal voltage reference is provided, or the ADC14155 can be operated with an external reference.
The ADC14155 can be configured for either single-ended or differential operation. Clock mode (differential versus single-ended)
and output data format (offset binary versus 2's complement) are pin-selectable. A duty cycle stabilizer maintains performance
over a wide range of clock duty cycles.
The ADC14155 is available in a 48-lead thermally ehanced mult-layer ceramic quad package and operates over the military temperature
range of -55°C to +125°C.
