LTC6605IDJC-10#TRPBF

Overview

The LTC6605IDJC-10#TRPBF is a dual matched 10MHz lowpass filter with low noise and low distortion differential amplifiers. It contains two independent fully differential amplifiers configured as matched second-order filters with internal laser-trimmed resistors and capacitors. The -3dB cutoff frequency is adjustable from 9.7MHz to 14MHz using an external resistor. Pin-selectable gain options include 0dB, 12dB, and 14dB. Supply voltage ranges from 2.7V to 5.25V. The device operates over a temperature range of -40°C to 85°C and is housed in a compact 22-pin 6mm x 3mm DFN package.

Feature Summary

• Dual matched second-order lowpass filters with integrated differential amplifiers
• Pin-selectable passband gain configurations for system flexibility
• Three-state BIAS pins enable power consumption management between shutdown and full performance modes
• Adjustable output common mode voltage control via dedicated VOCM pins

Applications

• Broadband wireless ADC driver and filtering
• Antialiasing filter applications
• Single-ended to differential signal conversion
• DAC smoothing filter circuits
• Zero-IF direct conversion receivers

Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging rather than tube packaging. Confirm the IDJC suffix indicates the industrial temperature grade (-40°C to 85°C) required for the application environment. Ensure the component matches the 22-lead DFN physical footprint during procurement validation.

Selection Notes

Select this component when precise channel-to-channel gain and phase matching are critical for differential signal paths. Consider the pin-selectable gain options to simplify circuit design without requiring external precision resistors. Evaluate the three-state BIAS functionality if dynamic power management or thermal constraints are present in the system architecture.

Part Context

This part belongs to the LTC6605 family of dual matched filter amplifiers. The 'I' designation specifies the industrial temperature range variant, distinct from the commercial grade 'C' version. The 'DJC' identifies the specific 22-lead plastic DFN package form factor used for surface mount assembly.

Replacement Considerations

LTC6605CDJC-10#TRPBF serves as a functional substitute within the same family, differing only in the guaranteed operating temperature range.
