FEATURES  
DESCRIPTION  
The LTC®1412 is a 12-bit, 3Msps, sampling A/D con-  
verter. This high performance device includes a high  
dynamic range sample-and-hold and a precision refer-  
ence. Operating from ±5V supplies it draws only 150mW.  
Sample Rate: 3Msps  
72dB S/(N + D) and 82dB SFDR at Nyquist  
±0.35LSB INL and ±0.25LSB DNL (Typ)  
Power Dissipation: 150mW  
External or Internal Reference Operation  
The ±2.5V input range is optimized for low noise and low  
distortion. Most high performance op amps also perform  
bestoverthisrange, allowingdirectcouplingtotheanalog  
inputs and eliminating the need for special translation  
circuitry. Outstanding AC performance includes 72dB  
S/(N + D) and 82dB SFDR at the Nyquist input frequency  
of 1.5MHz.  
True Differential Inputs Reject Common Mode Noise  
40MHz Full Power Bandwidth Sampling  
±2.5V Bipolar Input Range  
No Pipeline Delay  
28-Pin SSOP Package

APPLICATIONS  
Theuniquedifferentialinputsample-and-holdcanacquire  
single-ended or differential input signals up to its 40MHz  
bandwidth. The 60dB common mode rejection allows  
users to eliminate ground loops and common mode noise  
by measuring signals differentially from the source.

TheADChasahighspeed12-bitparalleloutputport.There  
is no pipeline delay in the conversion results. A separate  
convert start input and converter status signal (BUSY)  
ease connections to FIFOs, DSPs and microprocessors. A  
digital output driver power supply pin allows direct con-  
nection to 3V logic.
