UNBALANCED NOISE CURRENT (pA/Hz) LT6230/LT6230-10 LT6231/LT6232 215MHz, Rail-to-Rail Output, 1.1nV/Hz, 3.5mA Op Amp Family Fea T Descrip T n Low Noise Voltage: 1.1nV/Hz The LT 6230/LT6231/LT6232 are single/dual/quad low n Low Supply Current: 3.5mA/Amp Max noise, rail-to-rail output unity-gain stable op amps that n Low Offset Voltage: 350V Max 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 A 1 very low noise and supply current with a 215MHz gain- V LT6230-10: 1450MHz A 10 bandwidth product, a 70V/s slew rate and are optimized V 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: 40C to 85C that can be used to reduce the supply current to less n LT6230 Shutdown to 10A Maximum than 10A. 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 e I product of 1.9 per amplifier n SUPPLY is among the most noise efficient of any op amp. a T The LT6230/LT6230-10 are available in the 6-lead SOT-23 n Ultrasound Amplifiers package and the LT6231 dual is available in the 8-pin SO n Low Noise, Low Power Signal Processing package with standard pinouts. For compact layouts, n Active Filters the dual is also available in a tiny dual fine pitch leadless n Driving A/D Converters package (DFN). The LT6232 is available in the 16-pin n Rail-to-Rail Buffer Amplifiers SSOP package. L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
