LTC1164CN#PBF

Overview

The LTC1164CN#PBF is an ultraselective, low power 8th order elliptic bandpass filter manufactured by Linear Technology. It integrates a high-performance active filter with adjustable gain capabilities in a single package. The device operates within a supply voltage range of 2.7V to 5.5V and draws a typical quiescent current of 3mA. It features a center frequency determined by an external clock resistor, allowing for precise tuning. The component is housed in a 16-lead narrow plastic DIP package suitable for through-hole mounting.

Feature Summary

• Integrates an 8th-order elliptic bandpass filter response for high selectivity
• Provides adjustable gain control via an external resistor connection
• Operates on a single low-voltage power supply ranging from 2.7V to 5.5V
• Features low power consumption with a typical quiescent current of 3mA

Applications

• Communication systems requiring selective signal filtering
• Instrumentation where high Q-factor bandpass characteristics are needed
• Data acquisition front-ends for noise rejection
• Medical equipment signal processing circuits

Procurement Notes

Verify the specific suffix CN#PBF indicates the commercial temperature grade and lead-free packaging status. Confirm the 16-lead PDIP package availability matches your assembly requirements. Check for RoHS compliance documentation from Analog Devices prior to final procurement decisions.

Selection Notes

Select this component when an 8th-order elliptic response is required without discrete filter stages. Ensure the external clock frequency setting aligns with the desired center frequency. Verify that the adjustable gain feature meets the system's dynamic range requirements compared to fixed-gain alternatives.

Part Context

This part belongs to the LTC1164 family of integrated filters, which also includes lowpass variants like the LTC1164-6. Unlike the lowpass versions, the -8 variant provides bandpass characteristics. It serves as a drop-in replacement for older discrete filter designs in applications demanding high selectivity and low power consumption.

Replacement Considerations

Direct substitutes include other parts within the LTC1164 family such as the LTC1164-6 for lowpass applications. Cross-reference with LTC1064 series devices if clock-sweepable functionality is preferred over fixed center frequency operation.
