The MAX1005 is a combined digitizer and reconstruc-

tion integrated circuit designed to work in systems that

demodulate and modulate communications signals. It

integrates IF undersampling and signal synthesis func-

tions into a single, low-power circuit. Its analog-to-

digital converter (ADC) is used to directly sample or

undersample a downconverted RF signal, while its

digital-to-analog converter (DAC) recreates the IF sub-

carrier and transmission data. The MAX1005’s ADC is

ideal for undersampling applications, due to the analog

input amplifier’s wide (15MHz) bandwidth. The DAC

has very low glitch energy, which minimizes the trans-

mission of unwanted spurious signals. An on-chip

reference provides for low-noise ADC and DAC conver-

sions.

The MAX1005 provides a high level of signal integrity

from a low power budget. It operates from a single

power supply, or from separate analog and digital sup-

plies with independent voltages ranging from +2.7V to

+5.5V. The MAX1005 can operate with an unregulated

analog supply of 5.5V and a regulated digital supply

down to 2.7V. This flexible power-supply operation

saves additional power in complex digital systems.

The MAX1005 has three operating modes: transmit

(DAC active), receive (ADC active), and shutdown

(ADC and DAC inactive). In shutdown mode, the total

supply current drops below 1µA. The device requires

only 2.4µs to wake up from shutdown mode. The

MAX1005 is ideal for hand-held, as well as base-station

applications. It is available in a tiny 16-pin QSOP pack-

age specified for operation over both the commercial

and extended temperature ranges.
