描述
描述 The LT?1466L/LT1467 are dual/quad bipolar op amps that combine rail-to-rail input and output operation with precision specifications. Using a patented technique, both input stages of the LT1466L/LT1467L are trimmed: one at the negative supply and the other at the positive supply. The resulting common mode rejection of 83dB minimum is much better than other rail-to-rail input op amps. A minimum open-loop gain of 400V/mV into a 10K load virtually eliminates all gain error. Operation is specified for 3V, 5V and ±5V supplies. Unlike other rail-to-rai; amplifiers, the input offset voltage of 390μV maximum is guaranteed across the entire rail-to-rail input range, not just half supply. The graph below contrasts the V OS specifications of the LT1466L/LT1467L to a competitive part that is specified only at half supply. As can be seen, the LT1466L/LT1467L's limits are much tighter for inputs near either supply. The LT1466L is available in 8-lead PDIP and SO packages with the standard dual pinout. The LT1467L features the standard quad pinout and is available in a 16-lead narrow SO package.
