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)

■

f_CUTOFF: 14kHz (Max)

S/N Ratio: 72dB

■

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

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.

f_CUTOFF: 20kHz (Max)

S/N Ratio: 79dB

■

±0.1dB Passband Ripple Up to 0.9f_CUTOFF(Typ)

■

The typical passband ripple is ±0.1dB up to 0.9f_CUTOFF

42dB Attenuation at 1.3f_CUTOFF

■

The gain at f_CUTOFFis –0.7dB. The transition band of the

Wide Dynamic Range, 75dB or More (S/N + THD),

Under Single 5V Operation

Wideband Noise: 120µV_RMS

Clock-to-f_CUTOFFRatio: 50:1

■

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

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
