LT6202/LT6203/LT6204 Single/Dual/Quad 100MHz, Rail-to-Rail Input and Output, Ultralow 1.9nV/√Hz Noise, Low Power Op Amps FEATURESDESCRIPTION n Low Noise Voltage: 1.9nV/√Hz (100kHz) The LT®6202/LT6203/LT6204 are single/dual/quad low n Low Supply Current: 3mA/Amp Max noise, rail-to-rail input and output unity gain stable op amps n Gain Bandwidth Product: 100MHz that feature 1.9nV/√Hz noise voltage and draw only 2.5mA n Dual LT6203 in Tiny DFN Package of supply current per amplifier. These amplifiers combine n Low Distortion: –80dB at 1MHz very low noise and supply current with a 100MHz gain n Low Offset Voltage: 500µV Max bandwidth product, a 25V/µs slew rate, and are optimized n Wide Supply Range: 2.5V to 12.6V for low supply signal conditioning systems. n Input Common Mode Range Includes Both Rails These amplifiers maintain their performance for supplies n Output Swings Rail-to-Rail from 2.5V to 12.6V and are specified at 3V, 5V and ±5V n Common Mode Rejection Ratio 90dB Typ supplies. Harmonic distortion is less than –80dBc at n Unity Gain Stable 1MHz making these amplifiers suitable in low power data n Low Noise Current: 1.1pA/√Hz acquisition systems. n Output Current: 30mA Min n Operating Temperature Range –40°C to 125°C The LT6202 is available in the 5-pin TSOT-23 and the 8-pin n Low Profile (1mm) SOT-23 (ThinSOT™) Package SO, while the LT6203 comes in 8-pin SO and MSOP pack- ages with standard op amp pinouts. For compact layouts APPLICATIONS the LT6203 is also available in a tiny fine line leadless n package (DFN), while the quad LT6204 is available in the Low Noise, Low Power Signal Processing n 16-pin SSOP and 14-pin SO packages. These devices Active Filters n can be used as plug-in replacements for many op amps Rail-to-Rail Buffer Amplifiers n to improve input/output range and noise performance.
