description

The TLC04/MF4A-50 and TLC14/MF4A-100 are monolithic Butterworth low-pass switched-capacitor filters.

Each is designed as a low-cost, easy-to-use device providing accurate fourth-order low-pass filter functions in

circuit design configurations.

Each filter features cutoff frequency stability that is dependent only on the external-clock frequency stability. The

cutoff frequency is clock tunable and has a clock-to-cutoff frequency ratio of 50:1 with less than ±0. 8% error

for the TLC04/MF4A-50 and a clock-to-cutoff frequency ratio of 100:1 with less than ±1% error for the

TLC14/MF4A-100. The input clock features self-clocking or TTL- or CMOS-compatible options in conjunction

with the level shift (LS) terminal.

The TLC04C/MF4A-50C and TLC14C/MF4A-100C are characterized for operation from 0°C to 70°C. The

TLC04I/MF4A-50I and TLC14I/MF4A-100I are characterized for operation from –40°C to 85°C. The

TLC04M/MF4A-50M and TLC14M/MF4A-100M are characterized over the full military temperature range of

–55°C to 125°C.
