FEATURES  
DESCRIPTIO  
The LTC®1405 is a 5Msps, 12-bit sampling A/D converter  
that draws only 115mW from either single 5V or dual ±5V  
supplies. Thiseasy-to-usedeviceincludesahighdynamic  
range sample-and-hold, a precision reference and a PGA  
input circuit.  
5Msps Sample Rate  
Low Power Dissipation: 115mW  
Single 5V Supply or ±5V Supplies  
71.3dB S/(N + D) and 85dB SFDR at Nyquist  
100MHz Full-Power Bandwidth Sampling  
Input PGA  
TheLTC1405hasaflexibleinputcircuitthatallowsfull-scale  
inputrangesof±2.048V,±1.024Vand±0.512V. Theinput  
common mode range is rail-to-rail and a common mode

True Differential Inputs with 75dB CMRR  
Maximum DC specs include ±1LSB INL and ±1LSB DNL  
over temperature. Outstanding AC performance includes  
71.3dB S/(N + D) and 85dB SFDR at the Nyquist input fre-  
quency of 2.5MHz.  
Pin-Compatible 10Msps Version (LTC1420)
