♦ Differential-Input, 5-Bit ADC
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
und e rs a mp le a d ownc onve rte d RF s ig na l, 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-
mis s ion of unwa nte d s p urious s ig na ls . An on-c hip
reference provides for low-noise ADC and DAC conver-
sions.
♦ Differential-Output, 7-Bit DAC
♦ 15Msps Min Conversion Rate
♦ 25MHz -1dB Full-Power Bandwidth
♦ 44dB SFDR for ADC
39dB at 10.7MHz SFDR (Imaged) for DAC
♦ Internal Voltage Reference
♦ Parallel Logic Interface
♦ Single-Supply Operation (+2.7V to +5.5V)
♦ 0.1µA Low-Power Shutdown Mode
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 a c tive ), re c e ive (ADC a c tive ), a nd s hutd own
(ADC and DAC inactive). In shutdown mode, the total
supply current drops below 1µA. The device requires
only 2.4µs to wa ke up from s hutd own mod e . 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.
