Dual, 8-Bit, 40MHz, Current/Voltage,  
Simultaneous-Output DACs  
General Description  
Features  
The MAX5186 contains two 8-bit, simultaneous-update,  
current-output digital-to-analog converters (DACs)  
designed for superior performance in communications  
systems requiring analog signal reconstruction with low  
distortion and low-power operation. The MAX5189 pro-  
vides equal specifications, with on-chip precision resis-  
tors for voltage output operation. The MAX5186/  
MAX5189 are designed for a 10pVs glitch operation to  
minimize unwanted spurious signal components at the  
output. An on-board +1.2V bandgap circuit provides a  
well-regulated, low-noise reference that can be dis-  
abled for external reference operation.  
+2.7V to +3.3V Single-Supply Operation  
Wide Spurious-Free Dynamic Range: 70dB  
at f = 2.2MHz

Low-Current Standby or Full Shutdown Modes  
Internal +ꢂ.2V, Low-Noise Bandgap Reference  
Small 28-Pin QSOP Package  
The MAX5186/MAX5189 are designed to provide a high  
level of signal integrity for the least amount of power dissi-  
pation. Both DACs operate from a single supply voltage  
of +2.7V to +3.3V. Additionally, these DACs have three  
modes of operation: normal, low-power standby, and  
complete shutdown, which provides the lowest possible  
power dissipation with a 1µA (max) shutdown current. A  
fast wake-up time (0.5µs) from standby mode to full DAC  
operation allows power conservation by activating the  
DACs only when required.
