  description

  The LTC®6084/LTC6085 is a dual/quad, low-cost, low-offset, rail-to-rail input/output, unity-gain stabilized CMOS op amp with an input bias current of 1pA. A gain bandwidth of 1.5MHz and a slew rate of 0.5V/μs, combined with a wide supply range and a low offset voltage of 0.75mV, make the LTC6084/LTC6085 suitable for a wide range of applications, from data acquisition to medical devices and consumer electronics. The 110μA supply current and shutdown mode are ideal for signal processing applications that require high performance and very low power. The LTC6084/LTC6085 has an output stage that swings within 5mV of either power rail and is designed to maximize the signal dynamic range in low-power applications. The input common-mode range includes the entire supply voltage. These operational amplifiers are specified for 2.5V and 5V supply voltages and a temperature range of -40°C to 125°C. The dual-channel amplifier LTC6084 is available in an 8-pin MSOP and 10-pin DFN package. The quad amplifier LTC6085 is available in a 16-pin SSOP and DFN package.
