Description

The MSEPAF integrated circuit provides a continu-

ous time 4th order filter whose corner or center

frequencies can be programmed using a 10 bit

word serially loaded and stored in on-chip EEP-

ROM. The MSEPAF can be set as a lowpass or

a bandpass to 18 MHz from 500 kHz with one

external component. The device operates from

4.5V up to 5.5 VDC The accuracy of the MSEP-

AF is better than 1%. Temperarture stability is

better than discrete solutions using resistors,

capacitors and op amps.

The EEPROM technology for setting the frequency

requires 20V, which can be generated by the

system, and the device programmed in the field,

if desired.

The MSEPAF is available in a 16 pin bench or

system programmable SOIC.
