Features n LTC6605-10 Dual Matched 10MHz Filter with Low Noise, Low Distortion Differential Amplifier DESCRIPTION .. n n n n n n n Two Matched 10MHz 2nd Order Lowpass Filters with Differential Amplifiers Gain Match: ±0.35d B Max, Passband Phase Match: ±1.2° Max, Passband Single-Ended or Differential Inputs < - 90d Bc Distortion in Passband 2.1n V/√Hz Op Amp Noise Density Pin-Selectable Gain (0d B/12d B/14d B) Pin-Selectable Power Consumption (0.35m A/ 16.2m A/33.1m A) Rail-to-Rail Output Swing Adjustable Output mon Mode Voltage Control Buffered, Low Impedance Outputs 2.7V to 5.25V Supply Voltage Small 22-Pin 6mm × 3mm × 0.75mm DFN Package The LTC®6605-10 contains two independent, fully differential amplifiers configured as matched 2nd order 10MHz lowpass filters. The f- 3d B 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 patible with 16-bit dynamic range systems. The inputs can accept singleended or differential signals. An input pin is provided for each amplifier to set the mon 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. The LTC6605-10 is available in a pact 6mm × 3mm 22-pin leadless DFN package and operates over a - 40°C to 85°C temperature range. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
