GENERAL DESCRIPTION
The AD12400 is a 12-bit analog-to-digital converter (ADC)
with a transformer-coupled analog input and digital post-
processing for enhanced SFDR. The product operates at a 400
MSPS conversion rate with outstanding dynamic performance
in wideband carrier systems.
The AD12400 requires 3.8 V analog, 3.3 V digital, and 1.5 V
digital supplies, and provides a flexible encode signal that can
be differential or single-ended. No external reference is
required.
The AD12400 package style is an enclosed 2.9" × 2.6" × 0.6"
module. Performance is rated over a 0°C to 60°C case
temperature range.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
ESD CAUTION
ESD (electrostatic discharge) sensitive device.
Charged devices and circuit boards can discharge
without detection. Although this product features
patented or proprietary protection circuitry, damage may
occur on devices subjected to high energy ESD.
Therefore, proper ESD precautions should be taken to
avoid performance degradation or loss of functionality.
