feature 1.1nV/√Hz noise voltage and draw only 3.5mA of n Gain Bandwidth Product: supply current per amplifier. These amplifiers combine LT6230: 215MHz; AV ≥ 1 very low noise and supply current with a 215MHz gain- LT6230-10: 1450MHz; AV ≥ 10 bandwidth product, a 70V/µs slew rate and are optimized n Wide Supply Range: 3V to 12.6V for low supply voltage signal conditioning systems. The n Output Swings Rail-to-Rail LT6230-10 is a single amplifier optimized for higher gain n Common Mode Rejection Ratio: 115dB Typ applications resulting in higher gain bandwidth and slew n Output Current: 30mA rate. The LT6230 and LT6230-10 include an enable pin n Operating Temperature Range: –40°C to 85°C that can be used to reduce the supply current to less n LT6230 Shutdown to 10µA Maximum than 10µA. n LT6230/LT6230-10 in a Low Profile (1mm) The amplifier family has an output that swings within 50mV ThinSOT™ Package of either supply rail to maximize the signal dynamic range n Dual LT6231 in 8-Pin SO and Tiny DFN Packages in low supply applications and is specified on 3.3V, 5V and n LT6232 in a 16-Pin SSOP Package ±5V supplies. The en • √ISUPPLY product of 1.9 per amplifier is among the most noise efficient of any op amp.
