FEATURES  
DESCRIPTIO  
The LTC®1273/LTC1275/LTC1276 are 300ksps, sam-  
pling 12-bit A/D converters that draw only 75mW from  
single 5V or ±5V supplies. These easy-to-use devices  
come complete with 600ns sample-and-holds, precision  
references and internally trimmed clocks. Unipolar and  
bipolar conversion modes provide flexibility for various  
applications. They are built with LTBiCMOSTM switched  
capacitor technology.  
Single Supply 5V or ±5V Operation  
300ksps Sample Rate  
75mW (Typ) Power Dissipation  
On-Chip 25ppm/°C Reference  
Internal Synchronized Clock; No Clock Required  
High Impedance Analog Input  
70dB S/(N + D) and 77dB THD at Nyquist  
±1/2LSB INL and ±3/4LSB DNL Max (A Grade)  
ESD Protected On All Pins  
These devices have 25ppm/°C (max) internal references.  
The LTC1273 converts 0V to 5V unipolar inputs from a  
single 5V supply. The LTC1275/LTC1276 convert ±2.5V  
and ±5V respectively from ±5V supplies. Maximum DC  
specifications include ±1/2LSB INL, ±3/4LSB DNL and  
25ppm/°C full scale drift over temperature. Outstanding  
AC performance includes 70dB S/(N + D) and 77dB THD  
at the Nyquist input frequency of 150kHz.  
24-Pin Narrow PDIP and SW Packages  
Variety of Input Ranges:  
0V to 5V (LTC1273)  
±2.5V (LTC1275)  
±5V (LTC1276U)  
APPLICATIO S  
High Speed Data Acquisition  
The internal clock is trimmed for 2.7µs maximum conver-  
sion time. The clock automatically synchronizes to each  
sample command eliminating problems with asynchro-  
nous clock noise found in competitive devices. A high  
speed parallel interface eases connections to FIFOs, DSPs  
and microprocessors.
