MAX7407CSA+T

Overview

The MAX7407CSA+T is an 8th-order, lowpass, elliptic switched-capacitor filter operating from a single +3V supply. It features a sharp rolloff with a transition ratio of 1.2 and typical stopband rejection of 60dB. The corner frequency is clock-tunable from 1Hz to 10kHz using a 100:1 clock-to-corner ratio. Supply current is 2mA in operating mode and reduces to 0.2µA in shutdown mode. The device includes an offset adjustment pin (OS) for DC output level control and supports both internal oscillator and external clocking options.

Feature Summary

8th-order lowpass elliptic filter response
Clock-tunable corner frequency
Low-power shutdown mode
Offset adjustment capability

Applications

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

Procurement Notes

Verify the component authenticity by checking the manufacturer markings against official documentation. Confirm the package type matches the required specifications. Ensure the temperature range meets the application requirements. Check for any specific ordering suffixes that may affect performance or availability. Review the datasheet for any recent updates or changes to the part specifications.

Selection Notes

Select the MAX7407CSA+T when a single +3V supply is available and a steep rolloff is required. The 1.2 transition ratio provides sharper attenuation than the 1.5 ratio variants. Consider the internal oscillator or external clock option based on frequency stability needs. Ensure the input signal amplitude and load conditions are within the specified limits to maintain low distortion.

Part Context

The MAX7407 is part of the MAX7400 family of 8th-order lowpass elliptic switched-capacitor filters. This family includes variants with different supply voltages and transition ratios. The MAX7407 specifically operates at +3V and offers a transition ratio of 1.2. Other members include the MAX7400 (+5V, r=1.5), MAX7403 (+5V, r=1.2), and MAX7404 (+3V, r=1.5).
