Dual, 12-Bit, 40 MSPS MCM A/D Converter  
with Analog Input Signal Conditioning  
a
AD10242  
FEATURES  
T he AD10242 operates with ±5.0 V for the analog signal condi-  
Tw o Matched ADCs w ith Input Signal Conditioning  
Selectable Bipolar Input Voltage Range  
(؎0.5 V, ؎1.0 V, ؎2.0 V)  
Full MIL-STD-883B Com pliant  
80 dB Spurious-Free Dynam ic Range  
Trim m ed Channel-Channel Matching  
tioning with a separate +5.0 V supply for the analog-to-digital  
conversion. Each channel is completely independent allowing  
operation with independent encode or analog inputs. T he  
AD10242 also offers the user a choice of analog input signal  
ranges to minimize additional signal conditioning required for  
multiple functions within a single system. T he heart of the  
AD10242 is the AD9042 which is designed specifically for appli-  
cations requiring wide dynamic range.  
APPLICATIONS  
Radar Processing  
T he AD10242 is manufactured by Analog Devices on our  
MIL-PRF-38534 MCM line and is completely qualified. Units  
are packaged in a custom cofired ceramic 68-lead gull wing  
package and specified for operation from –55°C to +125°C.  
Contact the factory for additional custom options including  
those which allow the user to ac couple the ADC directly, by-  
passing the front end amplifier section. Also see the AD9042  
data sheet for additional details on ADC performance.

T he AD10242 is a complete dual signal chain solution including  
onboard amplifiers, references, ADCs, and output buffering pro-  
viding unsurpassed total system performance. Each channel is  
laser trimmed for gain and offset matching and provides channel-  
to-channel crosstalk performance better than 80 dB. The AD10242  
utilizes two each of the AD9631, OP279, and the AD9042 in a  
custom MCM to gain space, performance, and cost advantages  
over solutions previously available.  
P RO D UCT H IGH LIGH TS  
1. Guaranteed sample rate of 40 MSPS.  
2. Dynamic performance specified over entire Nyquist band;  
spurious signals @ 80 dBc for –1 dBFS input signals.  
3. Low power dissipation: <2 W off ±5.0 V supplies.  
4. User defined input amplitude.  
5. Packaged in 68-lead ceramic leaded chip carrier.
