MAX7414CPA

Overview

The MAX7414CPA is a fifth-order, lowpass switched-capacitor filter designed for single-supply operation at +3V. It delivers a Bessel frequency response with a clock-tunable corner frequency ranging from 1Hz to 15kHz. The device draws 1.2mA in operating mode and reduces current to 0.2µA in shutdown mode. It features low output offset of ±4mV and is housed in an 8-pin DIP package.

Feature Summary

• Provides fifth-order lowpass filtering with Bessel response characteristics
• Supports clock-tunable corner frequencies between 1Hz and 15kHz
• Operates on a single +3V supply with integrated shutdown capability

Applications

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

Procurement Notes

Verify the manufacturer designation carefully, as Maxim Integrated products are now part of Analog Devices Inc. Confirm the specific suffix indicates the commercial temperature range and PDIP-8 packaging. Ensure the component matches the original Maxim Integrated datasheet specifications for the MAX7414 series.

Selection Notes

Select this component when a Bessel response is required for linear phase characteristics. Choose the MAX7414 over the MAX7410 if the system operates on a +3V supply rather than +5V. Verify that the external clock frequency can be adjusted to achieve the desired cutoff frequency within the 1Hz to 15kHz range.

Part Context

This component belongs to the MAX7409/MAX7410/MAX7413/MAX7414 family of fifth-order lowpass switched-capacitor filters. The MAX7414 variant is specifically optimized for +3V single-supply applications, distinguishing it from the +5V MAX7410 while sharing similar performance metrics and package options.

Replacement Considerations

Public confirmed substitute part numbers: MAX7410EPA (requires +5V supply), MAX7413CPA (compatible +3V supply).
