LTC1069-6

Single Supply, Very Low

Power, Elliptic Lowpass Filter

FEATURES

DESCRIPTION

The LTC^®1069-6 is a monolithic low power, 8th order low-

pass filter optimized for single 3V or single 5V supply

operation. The LTC1069-6 typically consumes 1mA under

single 3V supply operation and 1.2mA under 5V operation.

8th Order Elliptic Filter in SO-8 Package

Single 3V Operation: Supply Current: 1mA (Typ)

: 14kHz (Max) S/N Ratio: 72dB

CUTOFF

Single 5V Operation: Supply Current: 1.2mA (Typ)

: 20kHz (Max) S/N Ratio: 79dB

CUTOFF

The cutoff frequency of the LTC1069-6 is clock tunable and it

is equal to the clock frequency divided by 50. The input signal

is sampled twice per clock cycle to lower the risk of aliasing.

Under Single 5V Operation

LTC1069-6 features progressive attenuation reaching

42dB at 1.3f_CUTOFFand 70dB at 2.1f_CUTOFF. The maximum

stopband attenuation is 72dB.

Wideband Noise: 120µV

RMS

Ratio: 50:1

Clock-to-f

CUTOFF

The LTC1069-6 can be clock tuned for cutoff frequencies

up to 20kHz (single 5V supply) and for cutoff frequencies

up to 14kHz (single 3V supply).

Internal Sample Rate: 100:1

APPLICATIONS

The low power feature of the LTC1069-6 does not penalize

the device’s dynamic range. With single 5V supply and

an input range of 0.4V_RMSto 1.4V_RMS, the Signal-to-

(Noise + THD) ratio is ≥70dB. The wideband noise of the
