Low Noise Voltage: 1.9nV/√Hz (100kHz) Low Supply Current: 3mA/Amp Max Gain Bandwidth Product: 100MHz Dual LT6203 in Tiny DFN Package Low Distortion: –80dB at 1MHz Low Offset Voltage: 500µV Max Wide Supply Range: 2.5V to 12.6V Input Common Mode Range Includes Both Rails Output Swings Rail-to-Rail Common Mode Rejection Ratio 90dB Typ Unity Gain Stable Low Noise Current: 1.1pA/√Hz Output Current: 30mA Min Operating Temperature Range –40°C to 85°C
The LT®6202/LT6203/LT6204 are single/dual/quad low noise, rail-to-rail input and output unity gain stable op amps that feature 1.9nV/√Hz noise voltage and draw only 2.5mA of supply current per amplifier. These amplifiers combine very low noise and supply current with a 100MHz gain bandwidth product, a 25V/µs slew rate, and are optimized for low supply signal conditioning systems. These amplifiers maintain their performance for supplies from 2.5V to 12.6V and are specified at 3V, 5V and ±5V supplies. Harmonic distortion is less than – 80dBc at 1MHz making these amplifiers suitable in low power data acquisition systems. The LT6202 is available in the 5-pin SOT-23 and the 8-pin SO, while the LT6203 comes in 8-pin SO and MSOP packages with standard op amp pinouts. For compact layouts the LT6203 is also available in a tiny fine line leadless package (DFN), while the quad LT6204 is available in the 16-pin SSOP and 14-pin SO packages. These devices can be used as plug-in replacements for many op amps to improve input/output range and noise performance.
