LTC1196/LTC1198  
8-Bit, SO-8, 1Msps ADCs  
with Auto-Shutdown Options  
FEATURES  
DESCRIPTION  
The LTC®1196ꢀLTC1198 are 600ns, 8-bit AꢀD converters  
with sampling rates up to 1MHz. They are offered in 8-pin  
SO packages and operate on 3V to 6V supplies. Power  
dissipation is only 10mW with a 3V supply or 50mW with  
a 5V supply. The LTC1198 automatically powers down  
to a typical supply current of 1nA whenever it is not  
performing conversions. These 8-bit switched-capacitor  
successive approximation ADCs include sample-and-  
holds. The LTC1196 has a differential analog input; the  
LTC1198 offers a software selectable /-channel MUX.

Converts 1MHz Inputs to 7 Effective Bits  
The 3-wire serial IꢀO, SO-8 packages, 3V operation and  
extremely high sample rate-to-power ratio make these  
ADCs an ideal choice for compact, high speed systems.

SO-8 Plastic Package  
These ADCs can be used in ratiometric applications or  
with external references. The high impedance analog in-  
puts and the ability to operate with reduced spans below  
1V full scale (LTC1196) allow direct connection to signal  
sources in many applications, eliminating the need for  
gain stages.
