MAX7413CPA

Overview

The MAX7413CPA is a fifth-order, lowpass switched-capacitor filter (SCF) from the Maxim Integrated product family. It operates from a single +3V supply and draws 1.2mA of supply current in active mode. The device features a Bessel response and allows for clock-tunable corner frequencies ranging from 1Hz to 15kHz. It includes a shutdown mode that reduces supply current to 0.2µA. The component is available in an 8-pin DIP package and offers a low output offset of ±4mV.

Feature Summary

• Provides fifth-order lowpass filtering with a Bessel response characteristic
• Operates from a single +3V power supply
• Features a clock-tunable corner frequency range from 1Hz to 15kHz
• Includes a shutdown mode for ultra-low power consumption

Applications

• ADC anti-aliasing
• DAC post-filtering
• Speech processing
• CT2 base stations
• Air-bag electronics

Procurement Notes

Verify the manufacturer origin carefully, as Analog Devices acquired Maxim Integrated. Confirm the specific suffix 'CPA' corresponds to the commercial temperature range and 8-pin PDIP package. Ensure the datasheet revision matches the required specifications for your design.

Selection Notes

Select this component when a Bessel response is required for linear phase characteristics. Choose the MAX7413 over the MAX7410 if a +3V single supply is preferred. Verify that the external clock frequency can be generated within the required limits to achieve the desired 1Hz to 15kHz corner frequency range.

Part Context

The MAX7413 is part of a family of fifth-order switched-capacitor filters that includes the MAX7409, MAX7410, and MAX7414. These devices are designed for low-power applications requiring precise analog filtering without external inductors or large capacitors.

Replacement Considerations

The MAX7410 is a functional substitute but requires a +5V supply instead of +3V. The MAX7409 shares the +3V supply and Bessel response but may have different pinout or electrical tolerances. Verify compatibility before substitution.
