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.

I/O DESCRIPTION AGND 6 I Analog ground. The noninverting input to the operational amplifiers of the Butterworth fourth-order low-pass filter. CLKIN 1 I Clock in. CLKIN is the clock input terminal for CMOS-compatible clock or self-clocking options. For either option, LS is at VCC– . For self-clocking, a resistor is connected between CLKIN and CLKR and a capacitor is connected from CLKIN to ground. CLKR 2 I Clock R. CLKR is the clock input for a TTL-compatible clock. For a TTL clock, LS is connected to midsupply and CLKIN can be left open, but it is recommended that it be connected to either VCC+ or VCC– .
