FEATURES  
DESCRIPTIO  
The LTC®1419 is a 1µs, 800ksps, 14-bit sampling  
A/D converter that draws only 150mW from ±5V supplies.  
This easy-to-use device includes a high dynamic range  
sample-and-hold and a precision reference. Two digitally  
selectable power shutdown modes provide flexibility for  
low power systems.  
■
Sample Rate: 800ksps  
■
Power Dissipation: 150mW  
■
81.5dB S/(N + D) and 93dB THD  
■
No Missing Codes  
No Pipeline Delay  
■
■
Nap and Sleep Shutdown Modes  
■
Operates with 2.5V Internal 15ppm/°C  
The LTC1419 has a full-scale input range of ± 2.5V. Out-  
standing AC performance includes 81.5dB S/(N + D) and  
93dB THD with a 100kHz input; 80dB S/(N + D) and 86dB  
THD at the Nyquist input frequency of 400kHz.

Theuniquedifferentialinputsample-and-holdcanacquire  
single-ended or differential input signals up to its 20MHz  
bandwidth. The 60dB common mode rejection allows  
users to eliminate ground loops and common mode noise  
by measuring signals differentially from the source.

APPLICATIO S  
■
Telecommunications  
■
Digital Signal Processing  
The ADC has a µP compatible, 14-bit parallel output port.  
There is no pipeline delay in the conversion results. A  
separate convert start input and data ready signal (BUSY)  
ease connections to FIFOs, DSPs and microprocessors.
