FEATURES  
DESCRIPTIO  
TheLTC®1420isa10Msps,12-bitsamplingA/Dconverter  
that draws only 250mW from either single 5V or dual ±5V  
supplies. Thiseasy-to-usedeviceincludesahighdynamic  
range sample-and-hold, a precision reference and a PGA  
input circuit.  
10Msps Sample Rate  
Single 5V Supply or ±5V Supplies  
Integral Nonlinearity Error <0.35LSB  
Differential Nonlinearity <0.25LSB  
71dB S/(N + D) and 83dB SFDR at Nyquist  
100MHz Full-Power Bandwidth Sampling  
±2.048V, ±1.024V and ±0.512V Bipolar Input Range  
Input PGA  
The LTC1420 has a flexible input circuit that allows full-  
scale input ranges of ±2.048V ±1.024V and ±0.512V. The  
input common mode voltage is arbitrary, though a 2.5V  
reference is provided for single supply applications. The  
input PGA has a digitally selectable 1x or 2x gain.  
Out-of-Range Indicator  
True Differential Inputs with 75dB CMRR  
Power Dissipation: 250mW  
28-Pin Narrow SSOP Package  
Maximum DC specs include ±1LSB INL and ±1LSB DNL  
over temperature. Outstanding AC performance includes  
71dB S/(N + D) and 83dB SFDR at the Nyquist input  
frequency of 5MHz.  
U
APPLICATIO S  
Telecommunications  
Theuniquedifferentialinputsample-and-holdcanacquire  
single-ended or differential input signals up to its 100MHz  
bandwidth. The 75dB common mode rejection allows  
users to eliminate ground loops and common mode noise  
by measuring signals differentially from the source. A  
separate output logic supply allows direct connection to  
3V components.
