MAX7409EUA+T

The MAX7409EUA+T from Maxim Integrated Products is a 5th-order, lowpass, switched-capacitor filter in 8 pin µMAX package. This bessel filter provides low overshoot and fast settling. It operates with a 100:1 clock to corner frequency ratio. The device draw only 1.2mA of supply current and allow corner frequencies from 1Hz to 15KHz, making it ideal for low power post-DAC filtering and anti-aliasing applications. 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 is used in ADC anti-aliasing, DAC post filtering, air bag electronics, speech processing and CT2 base stations.

• Supply voltage range is 4.5V to 5.5V
• Operating temperature range from -40°C to +85°C
• Clock to corner tempco is 10ppm/°C, typical internal oscillator frequency is 30KHz
• Typical shutdown current is 0.2µA
• Low output offset of ±4mV
