LTC6085 - Quad 1.5MHz, Rail-to-Rail, CMOS Amplifiers

The LTC6084/LTC6085 are dual/quad, low cost, low offset, rail-to-rail input/output, unity-gain stable CMOS operational amplifiers that feature 1pA of input bias current. A 1.5MHz gain bandwidth, and 0.5V/μs slew rate, along with the wide supply range and a low 0.75mV offset, make the LTC6084/LTC6085 useful in an extensive variety of applications from data acquisition to medical equipment and consumer electronics. The 110μA supply current and the shutdown mode are ideal for signal processing applications which demand performance with minimal power. The LTC6084/LTC6085 have an output stage which swings within 5mV of either supply rail to maximize signal dynamic range in low supply applications. The input common mode range includes the entire supply voltage. These op amps are specified on power supply voltages of 2.5V and 5V from –40°C to 125°C. The dual amplifier LTC6084 is available in 8-lead MSOP and 10-lead DFN packages. The quad amplifier LTC6085 is available in 16-lead SSOP and DFN packages.
