LTC6084/LTC6085 Dual/Quad 1.5MHz, Rail-to-Rail, CMOS Ampli ers FEATURES DESCRIPTION n Low Offset Voltage: 750V Maximum The LTC 6084/LTC6085 are dual/quad, low cost, low offset, n Low Offset Drift: 5V/C Maximum rail-to-rail input/output, unity-gain stable CMOS operational n Low Input Bias Current: ampli ers that feature 1pA of input bias current. 1pA (Typical at 25C) A 1.5MHz gain bandwidth, and 0.5V/s slew rate, along 40pA (85C) with the wide supply range and a low 0.75mV offset, make n Rail-to-Rail Inputs and Outputs the LTC6084/LTC6085 useful in an extensive variety of ap- n 2.5V to 5.5V Operation Voltage plications from data acquisition to medical equipment and n Gain Bandwidth Product: 1.5MHz consumer electronics. The 110A supply current and the n CMRR: 70dB Minimum shutdown mode are ideal for signal processing applications n PSRR: 94dB Minimum which demand performance with minimal power. n Supply Current: 110A per Ampli er n The LTC6084/LTC6085 have an output stage which swings Shutdown Current: 1.1A per Ampli er n within 5mV of either supply rail to maximize signal dynamic Available in 8-Lead MSOP and 10-Lead DFN range in low supply applications. The input common Packages (LTC6084) and 16-Lead SSOP and DFN mode range includes the entire supply voltage. These op Packages (LTC6085) amps are speci ed on power supply voltages of 2.5V and 5V from 40C to 125C. The dual ampli er LTC6084 is APPLICATIONS available in 8-lead MSOP and 10-lead DFN packages. The quad ampli er LTC6085 is available in 16-lead SSOP and n Portable Test Equipment DFN packages. n Medical Equipment n L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
