ADC12L080 12-Bit, 80 MSPS, 450 MHz Bandwidth A/D Converter with Internal Reference  
Check for Samples: ADC12L080

FEATURES  
DESCRIPTION  
The ADC12L080 is a monolithic CMOS analog-to-  
digital converter capable of converting analog input  
signals into 12-bit digital words at 80 Megasamples  
2
Single Supply Operation  
Low Power Consumption  
Power Down Mode  
per second (MSPS). This converter uses  
a
Internal or External Reference  
differential, pipeline architecture with digital error  
correction and an on-chip sample-and-hold circuit to  
minimize die size and power consumption while  
providing excellent dynamic performance. The  
ADC12L080 can be operated with either the internal  
or an external reference. Operating on a single 3.3V  
power supply, this device consumes just 425 mW at  
80 MSPS, including the reference current. The Power  
Down feature reduces power consumption to just 50  
mW.  
Selectable Offset Binary or 2's Complement  
Data Format  
Pin-Compatible with ADC12010, ADC12020,  
ADC12040, ADC12L063, ADC12L066  
APPLICATIONS  
Ultrasound and Imaging  
Instrumentation  
Cellular Base Stations/Communication  
Receivers  
The differential inputs provide a full scale input swing  
equal to ±VREF. The buffered, high impedance, single-  
ended external reference input is converted on-chip  
to a differential reference for use by the processing  
circuitry. Output data format may be selected as  
either offset binary or two's complement.  
Sonar/Radar  
xDSL  
Wireless Local Loops  
Data Acquisition Systems  
DSP Front Ends  
This device is available in the 32-lead LQFP package  
and operates over the industrial temperature range of  
40°C to +85°C.  
KEY SPECIFICATIONS  
Full Power Bandwidth: 450 MHz  
DNL: ±0.4 LSB (typ)  
SNR (fIN = 10 MHz): 66 dB (typ)  
SFDR (fIN = 10 MHz): 80 dB (typ)  
Power Consumption, 80 MHz  
Operating: 425 mW (typ)
