Product Overview

The MAX7422EUA+ is a 5th order low pass, switched capacitor filter in 8 pin µMAX package. This is an elliptic low pass filter provides sharp roll-off with good stop band rejection. It operates with a 100:1 clock to corner frequency ratio. Two clocking options are available on this device, self-clocking (through the use of an external capacitor) or external clocking for tighter corner-frequency control. An offset adjust pin allows for adjustment of the DC output level. It uses an alternative approach which is to emulate a passive network using switched-capacitor integrators with summing and scaling. It is used in DAC post filtering, air-bag electronics and CT2 base stations.
  • Supply voltage range is 2.7V to 3.6V
  • Operating temperature range from -40°C to 85°C
  • Typical corner frequency range from 100:1 to 45KHz at VIN = 2.5Vp-p
  • Clock to corner tempco of 10ppm
  • °C, typical internal oscillator frequency is 87KHz
  • Typical supply current is 2.6mA (operating mode, no load)
  • Typical shutdown current is 0.2µA
