ADC14155

14-Bit, 155 MSPS, 1.1 GHz Bandwidth A/D Converter

General Description

Features

The ADC14155 is a high-performance CMOS analog-to-dig-

ital 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 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 ADC14155 operates from

dual +3.3V and +1.8V power supplies and consumes 967 mW

of power at 155 MSPS.

Internal sample-and-hold circuit

Low power consumption

Internal precision 1.0V reference

Single-ended or Differential clock modes

Data Ready output clock

Clock Duty Cycle Stabilizer

Dual +3.3V and +1.8V supply operation (+/- 10%)

Power-down mode

Offset binary or 2's complement output data format

48-pin LLP package, (7x7x0.8mm, 0.5mm pin-pitch)

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 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 com-

plement) are pin-selectable. A duty cycle stabilizer maintains

performance over a wide range of clock duty cycles.

■

Applications

The ADC14155 is available in a 48-lead LLP package and

operates over the industrial temperature range of −40°C to

+85°C.
