LTC1564

10kHz to 150kHz

Digitally Controlled

Antialiasing Filter and 4-Bit P.G.A.

DESCRIPTIO

The LTC

1564 is a new type of continuous time filter for

antialiasing, reconstruction and other band-limiting appli-

cations. No other analog components or filter expertise are

needed to use it. There is one analog input pin and one

analog output pin. The cutoff frequency (f

) and gain are

programmable while the shape of the lowpass response is

fixed. A latching digital interface stores f

and gain settings

or it can be bypassed for control directly from the pins. The

LTC1564 operates from 2.7V to 10V total (single or split

supplies) and comes in a 16-pin surface mount SSOP.

The LTC1564 is a rail-to-rail high resolution 8th-order

lowpass filter with two stopband notches, giving approxi-

mately 100dB attenuation at 2.5 times the passband cutoff

frequency f

(a de-facto standard for DSP front ends).

Signals with low or variable levels can be normalized with

the built-in variable gain that reduces input-referred noise

with increasing gain for a typical dynamic range (maxi-

mum signal level to minimum noise) of 122dB (20 equiva-

lent bits) with 20kHz f

and 118dB at 100kHz f

on a

±5V

supply.

Other frequency-response shapes can be provided upon

request. Please contact LTC Marketing.
