GENERAL DESCRIPTION
The AD10242 is a complete dual signal chain solution including
on-board amplifiers, references, ADCs, and output buffering
providing 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 AD9632, OP279, and AD9042 in a cus-
tom MCM to gain space, performance, and cost advantages over
solutions previously available.
The AD10242 operates with ± 5.0 V for the analog signal condi-
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. The AD10242
also offers the user a choice of analog input signal ranges to mini-
mize additional signal conditioning required for multiple functions
within a single system. The heart of the AD10242 is the AD9042,
which is designed specifically for applications requiring wide
dynamic range.
The AD10242 is manufactured on Analog Devices’
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
that allow the user to ac couple the ADC directly, bypassing the
front end amplifier section. Also see the AD9042 data sheet for
additional details on ADC performance.
PRODUCT HIGHLIGHTS
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.
