LTC6240/LTC6241/LTC6242 Single/Dual/Quad 18MHz, Low Noise, Rail-to-Rail Output, CMOS Op Amps FEATURES DESCRIPTION n 0.1Hz to 10Hz Noise: 550nV The LTC 6240/6241/LTC6242 are single, dual and quad P-P n Input Bias Current: low noise, low offset, rail-to-rail output, unity gain stable 0.2pA (Typ at 25C) CMOS op amps that feature 1pA of input bias current. Input 1pA Max (LTC6240) bias current is guaranteed to be 1pA max on the single n Low Offset Voltage: 125V Max LTC6240. The 0.1Hz to 10Hz noise of only 550nV , along P-P n Low Offset Drift: 2.5V/C Max with an offset of just 125V are signi cant improvements n Gain Bandwidth Product: 18MHz over traditional CMOS op amps. Additionally, noise is n Output Swings Rail-to-Rail guaranteed to be less than 10nV/Hz at 1kHz. An 18MHz n Supply Operation: gain bandwidth, and 10V/s slew rate, along with the wide 2.8V to 6V LTC6240/LTC6241/LTC6242 supply range and low input capacitance, make them perfect 2.8V to 5.5V LTC6240HV/LTC6241HV/LTC6242HV for use as fast signal processing ampli ers. n Low Input Capacitance These op amps have an output stage that swings within n H-Grade Temperature Range: 40C to 125C 30mV of either supply rail to maximize the signal dynamic n Single LTC6240 in 5-Pin Low Pro le (1mm) range in low supply applications. The input common mode ThinSOT Package and 8-Pin SO for PCB Guard Ring range extends to the negative supply. They are fully speci- n Dual LTC6241 in 8-Pin SO and Tiny DFN Packages ed on 3V and 5V, and an HV version guarantees operation n Quad LTC6242 in 16-Pin SSOP and 5mm 3mm on supplies up to 5V.
