FEATURES  
DESCRIPTION  
The LTC®6362 is a low power, low noise differential op  
amp with rail-to-rail input and output swing that has been  
optimized to drive low power SAR ADCs. The LTC6362  
draws only 1mA of supply current in active operation, and  
features a shutdown mode in which the current consump-  
tion is reduced to 70μA.

The amplifier may be configured to convert a single-  
ended input signal to a differential output signal, and is  
capable of being operated in an inverting or noninverting  
configuration.

Low offset voltage, low input bias current, and a stable  
high impedance configuration make this amplifier suit-  
able for use not only as an ADC driver but also earlier in  
the signal chain, to convert a precision sensor signal to  
a balanced (differential) signal for processing in noisy  
industrial environments.
