3 Description

The ADC14155QML-SP 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 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 3.3-V and 1.8-V power supplies

and consumes 967 mW of power at 155 MSPS.

The separate 1.8-V 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-V internal voltage reference is provided, or

the ADC14155 can be operated with an external

reference. The Clock mode (differential versus singleended)

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 ADC14155QML-SP is available in a 48-lead

thermally enhanced multi-layer ceramic quad

package and operates over the military temperature

range of –55°C to +125°C.
