HMXADC9225  
Radiation Hardened 12-Bit, 20 MSPS  
Monolithic A/D Converter  
The HMXADC9225 is a radiation hardened monolithic, single supply, 12-bit, 20  
MSPS, analog-to-digital converter with an on-chip, high performance sample-and-  
hold amplifier. The HMXADC9225 uses a multistage differential pipelined  
architecture with output error correction logic to provide 12-bit accuracy at 20 MSPS  
data rates, and guarantees no missing codes over the full operating temperature  
range.  
The HMXADC9225 is fabricated on a radiation hardened SOI-IV Silicon On Insulator  
(SOI) process with very low power consumption.  
The input of the HMXADC9225 allows for easy interfacing to space and military imaging, sensor, and communications  
systems. With a truly differential input structure, the user can select a variety of input ranges and offsets including single-  
ended applications. The dynamic performance is excellent.  
The sample-and-hold amplifier (SHA) is well suited for both multiplexed systems that switch full-scale voltage levels in  
successive channels and sampling single-channel inputs at frequencies up to and well beyond the Nyquist rate.  
A single clock input is used to control all internal conversion cycles. The digital output data is presented in straight binary  
output format.  
FEATURES  
ƒ Monolithic 12-Bit, 20 MSPS A/D Converter  
ƒ Rad Hard: >500k Rad(Si) Total Dose  
ƒ Single +5 V Analog Supply  
ƒ Complete On-Chip S/H Amplifier  
ƒ Straight Binary Output Data  
Low Power  
The HMXADC9225 at 345 mW consumes a fraction of the  
power of presently available in existing monolithic  
solutions.  
ƒ 5V or 3.3V Digital and I/O Supply  
ƒ No Missing Codes Guaranteed  
ƒ Differential Nonlinearity Error: 0.4 LSB  
ƒ Signal-to-Noise and Distortion Ratio: 69.6 dB  
ƒ Spurious-Free Dynamic Range: –81 dB  
ƒ 28-Lead Ceramic Flat Pack  
Output Enable (OE)  
The OE input allows user to put the tri-state digital outputs  
into a high impedance mode.  
Dual Power Supply Capability  
The HMXADC9225 uses a single +5 V power supply  
simplifying system power supply design. It also features a  
separate digital I/O power supply line to accommodate  
3.3V and 5V logic families.  
Mixed Signal Rad Hard Process  
The HMXADC9225 is fabricated on space qualified SOI  
CMOS process. High-speed precision analog circuits  
are now combined with high-density logic circuits that  
can reliably withstand the harshest environments.  
On-Chip Sample-and-Hold (SHA)  
The versatile SHA input can be configured for either  
single-ended or differential inputs.  
Space Qualified Package  
The HMXADC9225 is packaged in a 28 lead ceramic flat  
pack.
