LTC1164-6CSW#PBF

Overview

The LTC1164-6CSW#PBF is a monolithic 8th order elliptic lowpass filter featuring clock-tunable cutoff frequency and low power supply current. It operates with ±5V supplies using only 4mA supply current while maintaining wideband noise below 110 µVRMS. With a single 5V supply, it provides up to 10kHz cutoff frequency and 80dB signal-to-noise ratio while consuming only 2.5mA. The device offers an elliptic lowpass rolloff with stopband attenuation of 64dB at 1.44 fCUTOFF and an fCLK-to-fCUTOFF ratio of 100:1 (Pin 10 to V–). For a ratio of 100:1, fCUTOFF can be clock-tuned up to 10kHz. For a f CLK-to-fCUTOFF ratio of 50:1 (Pin 10 to V +), the LTC1164-6 provides an elliptic lowpass filter with fCUTOFF frequencies up to 20kHz. When Pin 10 is connected to ground, the LTC1164-6 approximates an 8th order linear phase response with 65dB attenuation at 4.5 f–3dB and fCLK /f –3dB ratio of 160:1.

Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free compliance when sourcing this component. Confirm package type SW for 16-lead plastic SO. Check availability through authorized distributors as stock levels may vary. Ensure proper handling for surface mount assembly.

Selection Notes

Select the LTC1164-6CSW#PBF for applications requiring an 8th order elliptic lowpass filter with clock-tunable cutoff frequency. Consider the 16-lead SO package for surface mount designs. Evaluate power supply requirements and clock input compatibility before implementation.

Part Context

The LTC1164-6 is part of Analog Devices' family of low-power switched capacitor filters. It is pin compatible with the LTC1064-1. The CSW variant specifically denotes the 16-lead plastic small outline wide package. This component is designed for applications requiring high selectivity and low power consumption.

Replacement Considerations

The LTC1064-1 is a pin-compatible alternative offering similar functionality. Verify electrical specifications and package dimensions before substitution. Ensure clock input requirements and power supply ranges match the application needs.
