LMF100

SNOSBG9B –JULY 1999–REVISED JUNE 2015

LMF100 Dual High-Performance Switched Capacitor Filters

Not Recommended for New Designs

1 Features

3 Description

The LMF100 device consists of two independent

general-purpose, high-performance switched

•

Wide 4-V to 15-V Power Supply Range

Operation up to 100 kHz

Low Offset Voltage:

capacitor filters. With an external clock and two to

four resistors, each filter block can realize various

second-order and first-order filtering functions. Each

block has three outputs. One output can be

configured to perform either an allpass, highpass, or

notch function. The other two outputs perform

bandpass and lowpass functions. The center

frequency of each filter stage is tuned by using an

external clock or a combination of a clock and resistor

ratio. Up to a fourth-order biquadratic function can be

realized with one LMF100. Higher order filters are

implemented by simply cascading additional

packages, and all the classical filters (such as

Butterworth, Bessel, Elliptic, and Chebyshev) can be

realized.

–

Typically (50:1 or 100:1 mode):

–

Vos1 = ±5 mV

Vos2 = ±15 mV

Vos3 = ±15 mV

•

Low Crosstalk: –60 dB

Clock to Center Frequency Ratio Accuracy ±0.2%

(Typical)

•

f₀× Q Range up to 1.8 MHz

Pin-Compatible With MF10

2 Applications

The LMF100 is fabricated on TI’s high-performance

analog silicon gate CMOS process, LMCMOS™. This

allows for the production of a very low-offset, high-

frequency filter building block. The LMF100 is pin-

compatible with the industry standard MF10, but

provides greatly improved performance.

Factors and Higher Accuracy and Tunability
