LTC6605CDJC-7#PBF

Overview

The LTC6605CDJC-7#PBF is a dual matched 7MHz lowpass active filter with differential amplifiers. It features two independent channels with internal laser-trimmed resistors and capacitors for precise gain and phase matching. The device operates on a single supply voltage ranging from 2.7V to 5.25V. Pin-selectable gains include 0dB, 12dB, and 14dB. Power consumption is configurable via three-state BIAS pins, offering shutdown, medium power, or full power modes. The component is housed in a compact 22-pin 6mm x 3mm DFN package.

Feature Summary

• Dual matched second-order lowpass filters with integrated fully differential amplifiers
• Internal laser-trimmed components ensure tight channel-to-channel gain and phase matching
• Pin-selectable passband gain configurations without external components
• Three-state BIAS control allows selection between shutdown, medium power, and full power operation

Applications

• WCDMA 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 against official documentation to confirm temperature grade and packaging type. The CDJC variant indicates a commercial temperature range of 0°C to 70°C. Confirm lead-free finish status and tube packaging details directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when precise channel-to-channel matching is required for differential signal paths. Ensure the operating temperature range aligns with the commercial specification limits. Verify that the supply voltage and power consumption requirements fit within the available BIAS pin configurations. Check input common mode voltage ranges against the system signal levels.

Part Context

This part belongs to the LTC6605 family of dual matched filter amplifiers. Variants such as the IDJC differ primarily in their specified operating temperature ranges. The family utilizes internal laser trimming to achieve high precision without external calibration components. This specific model represents the commercial grade version of the 7MHz filter configuration.
