LTC1417  
Low Power 14-Bit, 400ksps  
Sampling ADC Converter  
with Serial I/O  
U
FEATURES  
DESCRIPTIO  
The LTC®1417 is a low power, 400ksps, 14-bit A/D con-  
verter. This versatile device can operate from a single 5V or  
±5V supplies. An onboard high performance sample-and-  
hold, a precision reference and internal trimming minimize  
external circuitry requirements. The low 20mW power  
dissipation is made even more attractive with two user-  
selectable power shutdown modes.  
16-Pin Narrow SSOP Package (SO-8 Footprint)  
Sample Rate: 400ksps  
±1.25LSB INL and ±1LSB DNL Max  
Power Dissipation: 20mW (Typ)  
Single Supply 5V or ±5V Operation  
Serial Data Output  
No Missing Codes Over Temperature  
Power Shutdown: Nap and Sleep  
The LTC1417 converts 0V to 4.096V unipolar inputs when  
using a 5V supply and ±2.048V bipolar inputs when using  
±5V supplies. DC specs include ±1.25LSB INL, ±1LSB  
DNLandnomissingcodesovertemperature. Outstanding  
AC performance includes 81dB S/(N + D) and 95dB THD  
at a Nyquist input frequency of 200kHz.  
External or Internal Reference  
Differential High Impedance Analog Input  
Input Range: 0V to 4.096V or ±2.048V  
81dB S/(N + D) and 95dB THD at Nyquist  
U
APPLICATIO S  
The internal clock is trimmed for 2µs maximum conver-  
sion time. A separate convert start input and a data ready  
signal (BUSY) ease connections to FIFOs, DSPs and  
microprocessors.
