AD8138  
HIGH PERFORMANCE ADC DRIVING  
The signal generator has a ground-referenced, bipolar output,  
i.e., it drives symmetrically above and below ground. Connecting  
VOCM to the CML pin of the AD9224 sets the output common-  
mode of the AD8138 at 2.5 V, which is the midsupply level for  
the AD9224. This voltage is bypassed by a 0.1 mF capacitor.  
The circuit in Figure 6 shows a simplified front-end connection  
for an AD8138 driving an AD9224, a 12-bit, 40 MSPS A/D  
converter. The ADC works best when driven differentially, which  
minimizes its distortion as described in its data sheet. The AD8138  
eliminates the need for a transformer to drive the ADC and  
performs single-ended-to-differential conversion, common-mode  
level-shifting, and buffering of the driving signal.  
The full-scale analog input range of the AD9224 is set to 4 V p-p,  
by shorting the SENSE terminal to AVSS. This has been deter-  
mined to be the scaling to provide minimum harmonic distortion.  
The positive and negative outputs of the AD8138 are connected  
to the respective differential inputs of the AD9224 via a pair of  
49.9 W resistors to minimize the effects of the switched-capacitor  
front end of the AD9224. For best distortion performance, it is  
run from supplies of ±5 V.  
For the AD8138 to swing at 4 V p-p, each output swings 2 V p-p  
while providing signals that are 180Њ out of phase. With a  
common-mode voltage at the output of 2.5 V, this means that  
each AD8138 output will swing between 1.5 V and 3.5 V.  
A ground-referenced 4 V p-p, 5 MHz signal at DIN+ was used  
to test the circuit in Figure 6. When the combined-device circuit  
was run with a sampling rate of 20 MSPS, the SFDR (spurious-  
free dynamic range) was measured at –85 dBc.  
The AD8138 is configured with unity gain for a single-ended  
input-to-differential output. The additional 23 W, 523 W total, at  
the input to –IN is to balance the parallel impedance of the 50 W  
source and its 50 W termination that drives the noninverting input.
