The f3dB of the fi lters is adjustable in the range of 9.7MHz to 14MHz. The internal op amps 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) 10MHz 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 LTC6605-10 is available in a compact 6mm * 3mm 22-pin leadless DFN package and operates over a 40 to 85 temperature range.
