Data Sheet  
AD9106  
FEATURES  
GENERAL DESCRIPTION  
Highly integrated quad DAC  
On-chip 4096 × 12-bit pattern memory  
On-chip DDS  
Power dissipation at 3.3 V, 4 mA output  
315 mW at 180 MSPS  
Sleep mode: < 5 mW at 3.3 V  
Supply voltage: 1.8 V to 3.3 V  
SFDR to Nyquist  
86 dBc at 1 MHz output  
85 dBc at 10 MHz output  
Phase noise at 1 kHz offset, 180 MSPS, 8 mA: −140 dBc/Hz  
Differential current outputs: 8 mA maximum at 3.3 V  
Small footprint 32-lead, 5 mm × 5 mm with 3.5 mm ×  
3.6 mm exposed paddle LFCSP  
The AD9106 TxDAC® and waveform generator is a high perform-  
ance quad DAC integrating on-chip pattern memory for complex  
waveform generation with a direct digital synthesizer (DDS). The  
DDS is a 12-bit output, up to 180 MHz master clock sinewave  
generator with a 24-bit tuning word allowing 10.8 Hz/LSB  
frequency resolution. The DDS has a single frequency output  
for all four DACs and independent programmable phase shift  
outputs for each of the four DACs.  
SRAM data can include directly generated stored waveforms,  
amplitude modulation patterns applied to DDS outputs, or  
DDS frequency tuning words.  
An internal pattern control state machine allows the user to  
program the pattern period for all four DACs as well as the start  
delay within the pattern period for the signal output on each  
DAC channel.  
Pb-free package  
APPLICATIONS  
An SPI interface is used to configure the digital waveform  
generator and load patterns into the SRAM.  
Medical instrumentation  
Ultrasound transducer excitation  
Portable instrumentation  
There are gain adjustment factors and offset adjustments  
applied to the digital signals on their way into the four DACs.  
Signal generators, arbitrary waveform generators  
The AD9106 offers exceptional ac and dc performance and  
supports DAC sampling rates up to 180 MSPS. The flexible  
power supply operating range of 1.8 V to 3.3 V and low power  
dissipation of the AD9106 make it well suited for portable and low  
power applications.
