LTC1418  
Low Power, 14-Bit, 200ksps  
ADC with Serial and Parallel I/O  
FEATURES  
DESCRIPTION  
The LTC®1418 is a low power, 200ksps, 14-bit A/D con-  
verter. Data output is selectable for 14-bit parallel or serial  
format. This versatile device can operate from a single 5V  
or 5Vsupply.Anonboardhighperformancesample-and-  
hold, a precision reference and internal timing minimize  
external circuitry requirements. The low 15mW power  
dissipation is made even more attractive with two user  
selectable power shutdown modes.

Differential High Impedance Analog Input  
The LTC1418 converts 0V to 4.096V unipolar inputs from  
a single 5V supply and 2.048V bipolar inputs from 5V  
supplies. DC specs include 1.25LSB INL, 1LSB DNL  
and no missing codes over temperature. Outstanding AC  
performance includes 82dB S/(N + D) and 94dB THD at  
the Nyquist input frequency of 100kHz.

APPLICATIONS  
The flexible output format allows either parallel or serial  
I/O. The SPI/MICROWIRE compatible serial I/O port can  
operate as either master or slave and can support clock  
frequencies from DC to 10MHz. A separate convert start  
input and a data ready signal (BUSY) allow easy control  
of conversion start and data transfer.
