Description
The LTC6605-10 contains two independent, fully differential amplifiers configured as matched 2nd order 10MHz lowpass filters. The f–3dB of the filters 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 single ended or differential signals. An input pin is provided for each amplifier 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 filter response. A single optional external resistor per channel can tailor the frequency response for each amplifier.
Three-state BIAS pins determine each amplifier’s power consumption, allowing a choice between shutdown, medium power or full power.
