LTC1419  
14-Bit, 800ksps Sampling  
A/D Converter with Shutdown  
Sample Rate: 800ksps  
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.  
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  
Reference or External Reference  
True Differential Inputs Reject Common Mode Noise  
20MHz Full-Power Bandwidth Sampling  
Bipolar Input Range: ±2.5V  
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.  
28-Pin SSOP and SO Packages  
Telecommunications  
Digital Signal Processing  
Multiplexed Data Acquisition Systems  
High Speed Data Acquisition  
Spectrum Analysis  
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.
