LTC6601IUF-2#TRPBF

Overview

The LTC6601IUF-2#TRPBF is a low power, low distortion, fully differential 2nd order active broadband RC filter and ADC driver. It features pin-configurable cutoff frequencies ranging from 5MHz to 27MHz and programmable gain between –17dB and +17dB. The device operates on a supply voltage range of 2.7V to 5.25V with a typical supply current of 16mA at 3V in low power mode. It is housed in a compact 4mm × 4mm 20-lead QFN package and is specified for an operating temperature range of –40°C to +85°C.

Feature Summary

• Pin-configurable filter response and gain settings
• Three-state BIAS pin for adjustable power consumption
• On-chip trimmed resistors and capacitors for consistent characteristics
• Rail-to-rail output swing with adjustable common mode voltage

Applications

• Differential A/D converter driver
• Antialiasing and reconstruction filtering
• Single-ended to differential conversion and amplification
• Common mode voltage translation
• Portable instrumentation signal processing

Procurement Notes

Verify the I suffix indicates the industrial temperature grade (–40°C to +85°C) and the TRPBF suffix denotes tape and reel packaging. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before procurement.

Selection Notes

Select this component when low distortion performance at high frequencies is prioritized over lowest noise. Compare against the LTC6601-1 if minimum noise is the primary requirement. Ensure the required cutoff frequency falls within the 5MHz to 27MHz configurable range.

Part Context

This part belongs to the LTC6601-2 family of active filters. It shares pin compatibility with the LTC6601-1 variant, which is optimized for lowest noise rather than lowest distortion. Both variants utilize the same 20-lead QFN package and offer similar configurability options.

Replacement Considerations

The LTC6601CUF-2#TRPBF serves as a direct replacement with identical electrical specifications but differs in the commercial temperature grade (0°C to 70°C). Verify that the application environment remains within the commercial range before substituting.
