LTC1164-5

Low Power 8th Order

Pin Selectable Butterworth

or Bessel Lowpass Filter

FEATURES

DESCRIPTIO

The LTC^®1164-5 is a monolithic 8th order filter; it approxi-

mates either a Butterworth or a Bessel lowpass response.

The LTC1164-5 features clock-tunable cutoff frequency

and low power consumption (4.5mA with ±5V supplies

and 2.5mA with single 5V supply).

■

Pin Selectable Butterworth or Bessel Response

■

4mA Supply Current with ±5V Supplies

■

f_CUTOFFup to 20kHz

■

100µV_RMSWideband Noise

■

THD < 0.02% (50:1, V_S= ±7.5V, V_IN= 2V_RMS

)

■

Operates with a Single 5V Supply (1V_RMSInput

Range)

Low power operation is achieved without compromising

noise or distortion performance. With ± 5V supplies and

10kHz cutoff frequency, the operating signal-to-noise

ratio is 86dB and the THD throughout the passband is

0.015%. Under the same conditions, a 77dB signal-to-

noise ratio and distortion is obtained with a single 5V

supply while the clock feedthrough is kept below the noise

level. The maximum signal-to-noise ratio is 92dB.

TTL/CMOS-Compatible Clock Input

Available in 14-Pin DIP and 16-Pin SO Wide

Packages

The LTC1164-5 approximates an 8th order Butterworth

response with a clock-to-cutoff frequency ratio of 100:1

(Pin 10 to V^–) or 50:1 double-sampled (Pin 10 to V⁺and

Pin1shortedtoPin13). Double-samplingallowstheinput

signal frequency to reach the clock frequency before any

aliasing occurrence. An 8th order Bessel response can

also be approximated with a clock-to-cutoff frequency

ratio of 140:1 (Pin 10 to ground). With ±7.5V supply, ±5V

supply and single 5V supply, the maximum clock fre-

quency of the LTC1164-5 is 1.5MHz, 1MHz and 1MHz

respectively. The LTC1164-5 is pin-compatible with the

LTC1064-2 and LTC-1064-3.
