DESCRIPTIO  
EATURE  
S
F
The LTC®1197/LTC1197L/LTC1199/LTC1199L are  
10-bit A/D converters with sampling rates up to 500kHz.  
They have 2.7V (L) and 5V versions and are offered in  
8-pin MSOP and SO packages. Power dissipation is typi-  
cally only 2.2mW at 2.7V (25mW at 5V) during full speed  
operation. The automatic power down reduces supply  
current linearly as sample rate is reduced. These 10-bit,  
switched-capacitor, successive approximation ADCs in-  
clude a sample-and-hold. The LTC1197/LTC1197L have a  
differential analog input with an adjustable reference pin.  
The LTC1199/LTC1199L offer a software-selectable  
2-channel MUX.

O U  
The 3-wire serial I/O, MSOP and SO-8 packages, 2.7V  
operation and extremely high sample rate-to-power ratio  
make these ADCs ideal choices for compact, low power  
high speed systems.

High Speed Data Acquisition  
Portable or Compact Instrumentation  
Low Power or Battery-Operated Instrumentation  
These circuits can be used in ratiometric applications or  
with external references. The high impedance analog  
inputs and the ability to operate with reduced spans below  
1V full scale (LTC1197/LTC1197L) allow direct connec-  
tion to signal sources in many applications, eliminating  
the need for gain stages.
