DESCRIPTIO
The LT®6013 and LT6014 op amps combine low noise and
high precision input performance with low power consumption and rail-to-rail output swing. The amplifiers are
stable in a gain of 5 or more and feature greatly improved
CMRR and PSRR versus frequency compared to other
precision op amps.
Input offset voltage is factory-trimmed to less than 35µV.
The low drift and excellent long-term stability ensure a
high accuracy over temperature and time. The 250pA
maximum input bias current and 120dB minimum voltage
gain further maintain this precision over operating
conditions.
The LT6013 and LT6014 operate from any supply voltage
from 2.7V to 36V and draw only 145µA of supply current
per amplifier on a 5V supply. The output swings to within
40mV of either supply rail, making the amplifiers very
useful for low voltage single supply operation.

The amplifiers are fully specified at 5V and ±15V supplies
and from –40°C to 85°C. The single LT6013 and dual
LT6014 are both available in SO-8 and space saving
3mm × 3mm DFN packages. For unity gain stable versions, refer to the LT6010 and LT6011 data sheets.
