ADC11C125

11-Bit, 125 MSPS, 1.1 GHz Bandwidth A/D Converter with

CMOS Outputs

General Description

Features

The ADC11C125 is a high-performance CMOS analog-to-

digital converter capable of converting analog input signals

into 11-Bit digital words at rates up to 125 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 1.1 GHz. The ADC11C125 operates from

dual +3.3V and +1.8V power supplies and consumes 608 mW

of power at 125 MSPS.

The separate +1.8V supply for the digital output interface al-

lows lower power operation with reduced noise. A power-

down feature reduces the power consumption to 5 mW while

still allowing fast wake-up time to full operation. In addition

there is a sleep feature which consumes 50 mW of power and

has a faster wake-up time.

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 ADC11C125 can

be operated with an external reference.

Power Consumption

Clock mode (differential versus single-ended) and output data

format (offset binary versus 2's complement) are pin-se-

lectable. A duty cycle stabilizer maintains performance over

a wide range of input clock duty cycles.

Applications

The ADC11C125 is pin compatible with the ADC12C170 and

the ADC14155.
