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 • √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.

Tools & Simulations
LTspice® is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits.
Models for the following parts are available in LTspice:
Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.
Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.
