Product Details
The LT6230/LT6231/LT6232 are single/dual/quad low noise, rail-to-rail output unity-gain stable op amps that feature 1.1nV/√Hz noise voltage and draw only 3.5mA of supply current per amplifier. These amplifiers combine very low noise and supply current with a 215MHz gain bandwidth product, a 70V/μs slew rate and are optimized for low supply voltage signal conditioning systems. The LT6230-10 is a single amplifier optimized for higher gain applications resulting in higher gain bandwidth and slew rate. The LT6230 and LT6230-10 include an enable pin that can be used to reduce the supply current to less than 10μA.
The amplifier family has an output that swings within 50mV of either supply rail to maximize the signal dynamic range in low supply applications and is specified on 3.3V, 5V and ±5V supplies. The en • √ISUPPLY product of 1.9 per amplifier is among the most noise efficient of any op amp.
The LT6230/LT6230-10 are available in the 6-lead SOT-23 package and the LT6231 dual is available in the 8-pin SO package with standard pinouts. For compact layouts, the dual is also available in a tiny dual fine pitch leadless package (DFN). The LT6232 is available in the 16-pin SSOP package.
