LT6600IDF-2.5#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT6600IDF-2.5#TRPBF is a fully differential amplifier integrated with a fourth-order lowpass filter featuring a 2.5MHz cutoff frequency and Chebyshev response. It operates on supply voltages ranging from 3V to 11V, drawing typical currents of 26mA at 3V and 33mA at 5V. The device provides an input-referred noise of 51μV RMS within the 10kHz to 2.5MHz bandwidth and achieves an 86dB signal-to-noise ratio at unity gain. It features a common-mode rejection ratio of 63dB and accepts inputs with bias currents averaging -35μA. Packaged in a DFN-12 format, it supports industrial temperature ranges from -40°C to 85°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Integrates a fully differential amplifier with a fourth-order lowpass filter approximating a Chebyshev frequency response.
• Requires only two external resistors to program differential gain while maintaining internally set cutoff frequencies.
• Provides adjustable output common mode voltage via the VOCM pin to accommodate ADC reference requirements.
• Supports single or dual power supplies including 3V, 5V, and ±5V configurations.

Instrumentation, Op Amps, Buffer Amps Applications

• High-speed ADC antialiasing filtering
• DAC smoothing and output filtering
• Networking or cellular basestation applications
• High-speed test and measurement equipment
• Medical imaging systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the specific suffix #TRPBF corresponds to the tape and reel packaging configuration rather than tube packaging. Confirm the 'I' grade designation indicates the specified -40°C to 85°C operating temperature range. Ensure the DFN-12 package footprint matches the design layout, noting the exposed pad connection requirements for thermal management and electrical grounding.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a compact solution combining amplification and anti-aliasing filtering is required. It serves as a drop-in replacement for standard differential amplifiers where fixed bandwidth filtering is acceptable. Consider the 2.5MHz cutoff frequency against system sampling rates to ensure adequate attenuation of image frequencies. Evaluate the trade-off between the fixed internal filter response and discrete designs requiring more external components.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT6600 series of very low noise differential amplifiers with integrated filters. Variants such as the LT6600-5, LT6600-10, LT6600-15, and LT6600-20 offer higher cutoff frequencies. The IDF suffix denotes the industrial temperature grade and DFN-12 package, while the TRPBF suffix indicates tape and reel availability.
