DESCRIPTIO  
FEATURES  
Sample Rate: 2.2Msps  
Outstanding Spectral Purity:  
80dB S/(N + D) and 95dB SFDR at 100kHz  
78dB S/(N + D) and 84dB SFDR at Nyquist  
Ultralow Distortion with Single-Ended or  
The LTC®1414 is a 14-bit, 2.2Msps, sampling A/D con-  
verter which draws only 175mW from ±5V supplies. This  
high performance ADC includes a high dynamic range  
sample-and-hold, a precision reference and requires no  
external components.  
Differential Inputs  
±2.5V Bipolar Input Range Eliminates Level Shifting  
and Rail-to-Rail Op Amp Requirements  
Easy Hookup for External or Internal Reference  
No Pipeline Delay  
Power Dissipation: 175mW on ±5V Supplies  
28-Pin Narrow SSOP Package  
The LTC1414s high performance sample-and-hold has a  
full-scale input range of ±2.5V. Outstanding AC perfor-  
mance includes 80dB S/(N + D) and 95dB SFDR with a  
100kHzinput.Theperformanceremains highattheNyquist  
input frequency of 1.1MHz with 78dB S/(N + D) and 84dB  
SFDR.  
Theuniquedifferentialinputsample-and-holdcanacquire
