Storage Temperature Range ................... 65 to 150
Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute  Maximum Rating condition for extended periods may affect device reliability and lifetime.
Note 2: All pins are protected by steering diodes to either supply. If any pin is driven beyond the LTC6605-7's supply voltage, the excess input current (current in excess of what it takes to drive that pin to the supply ail) should be limited to less than 10mA.
Note 3: A heat sink may be required to keep the junction temperature below the Absolute Maximum Rating when the output is shorted indefi nitely. Long-term application of output currents in excess of the Absolute Maximum Ratings may impair the life of the device.
Note 4: Both the LTC6605C and the LTC6605I are guaranteed functional over the operating temperature range 40 to 85.
Note 5: The LTC6605C is guaranteed to meet specifi ed performance from 0 to 70. The LTC6605C is designed, characterized and expected to meet specifi ed performance from 40 to 85, but is not tested or QA sampled at these temperatures. The LTC6605I is guaranteed to meet specifi ed performance from 40 to 85.

The LTC®6605-7 contains two independent, fully differential amplifi ers confi gured as matched 2nd order lowpass fi lters. The f3dB of the fi lters is adjustable in the range of 6.5MHz to 10MHz.

The internal op amps of LTC6605-7 are fully differential, feature very low noise and distortion, and are compatible with 16-bit dynamic range systems. The inputs can accept singleended or differential signals. An input pin is provided for each amplifi er to set the common mode level of the differential outputs.

Internal laser-trimmed resistors and capacitors determine a precise, very well matched (in gain and phase) 7MHz 2nd order fi lter response. A single optional external resistor per channel can tailor the frequency response for each amplifi er.

Three-state BIAS pins determine each amplifi er's power consumption, allowing a choice between shutdown, medium power or full power.

The LTC6605-7 is available in a compact 6mm * 3mm 22-pin leadless DFN package and operates over a 40 to 85 temperature range.
