LTC1069-6 Single Supply, Very Low Power, Elliptic Lowpass Filter
FEATURES
s s
DESCRIPTION
The LTC(R)1069-6 is a monolithic low power, 8th order lowpass 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. 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. The typical passband ripple is 0.1dB up to 0.9fCUTOFF. The gain at fCUTOFF is - 0.7dB. The transition band of the LTC1069-6 features progressive attenuation reaching 42dB at 1.3fCUTOFF and 70dB at 2.1fCUTOFF. The maximum stopband attenuation is 72dB. 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). 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 0.4VRMS to 1.4VRMS, the Signal-to-(Noise + THD) ratio is 70dB. The wideband noise of the LTC1069-6 is 125VRMS. Other filter responses with higher speed can be obtained. Please contact LTC Marketing for details. The LTC1069-6 is available in an 8-pin SO package.

The q denotes specifications which apply over the full operating temperature range. Note 1: The input offset voltage is measured with respect to AGND (Pin 1). The input (Pin 4) is also shorted to the AGND pin. The analog ground pin potential is internally set to (0.437)(VSUPPLY).
Note 2: The input voltage can swing to either rail (V + or ground); the output typically swings 50mV from ground and 0.8V from V +. Note 3: The LTC1069-6 is optimized for 3V and 5V operation. Although the device can operate with a single 10V supply or 5V, the total harmonic distortion will be degraded. For single 10V or 5V supply operation we recommend to use the LTC1069-1.

PIN FUNCTIONS
AGND (Pin 1): Analog Ground. The quality of the analog signal ground can affect the filter performance. For either single or dual supply operation, an analog ground plane surrounding the package is recommended. The analog ground plane should be connected to any digital ground at a single point. For single supply operation, Pin 1 should be bypassed to the analog ground plane with a 0.47F capacitor or larger. An internal resistive divider biases Pin 1 to 0.4366 times the total power supply of the device (Figure 1). That is, with a single 5V supply, the potential at Pin 1 is 2.183V 1%. As the LTC1069-6 is optimized for single supply operation, the internal biasing of Pin 1 allows optimum output swing. The AGND pin should be buffered if used to bias other ICs. Figure 2 shows the connections for single supply operation.

V +, V - (Pins 2, 7): Power Supply Pins. The V + (Pin 2) and the V - (Pin 7, if used) should be bypassed with a 0.1F capacitor to an adequate analog ground. The filter's power supplies should be isolated from other digital or high voltage analog supplies. A low noise linear supply is recommended. Switching power supplies will lower the signal-to-noise ratio of the filter. Unlike previous monolithic filters, the power supplies can be applied in any order, that is, the positive supply can be applied before the negative supply and vice versa. Figure 3 shows the connection for dual supply operation.

NC (Pins 3, 6): No Connection. Pins 3 and 6 are not connected to any internal circuitry; they should be tied to ground. VIN (Pin 4): Filter Input Pin. The Filter Input pin is internally connected to the inverting input of an op amp through a 50k resistor. CLK (Pin 5): Clock Input Pin. Any TTL or CMOS clock source with a square wave output and 50% duty cycle (10%) is an adequate clock source for the device. The power supply for the clock source should not necessarily be the filter's power supply. The analog ground of the filter should be connected to the clock's ground at a single point
APPLICATIONS INFORMATION
Temperature Behavior The power supply current of the LTC1069-6 has a positive temperature coefficient. The GBW product of its internal op amps is nearly constant and the speed of the device does not degrade at high temperatures. Figures 4a, 4b and 4c show the behavior of the passband of the device for various supplies and temperatures. The filter has a passband behavior which is temperature independent.

only. Table 1 shows the clock's low and high level threshold value for a dual or single supply operation. A pulse generator can be used as a clock source provided the high level ON time is greater than 0.42s (VS = 5V). Sine waves less than 100kHz are not recommended for clock frequencies because, excessive slow clock rise or fall times generate internal clock jitter. The maximum clock rise or fall time is 1s. The clock signal should be routed from the right side of the IC package to avoid coupling into any input or output analog signal path. A 1k resistor between the clock source and the Clock Input (Pin 5) will slow down the rise and fall times of the clock to further reduce charge coupling (Figure 1).

VOUT (Pin 8): Filter Output Pin. Pin 8 is the output of the filter, and it can source 8mA or sink 1mA. The total harmonic distortion of the filter will degrade when driving coaxial cables or loads less than 20k without an output buffer.

Clock Feedthrough The clock feedthrough is defined as the RMS value of the clock frequency and its harmonics that are present at the filter's Output (Pin 8). The clock feedthrough is tested with the Input (Pin 4) shorted to AGND (Pin 1) and depends on PC board layout and on the value of the power supplies. With proper layout techniques the values of the clock feedthrough are shown in Table 2.

quency contents much higher than the applied clock; their amplitude strongly depends on scope probing techniques as well as grounding and power supply bypassing. The clock feedthrough can be reduced by adding a single RC lowpass filter at the Output (Pin 8). Wideband Noise The wideband noise of the filter is the total RMS value of the device's noise spectral density and determines the operating signal-to-noise ratio. The frequency contents of the wideband noise lie within the filter's passband. The wideband noise cannot be reduced by adding post filtering. The total wideband noise is nearly independent of the clock frequency and depends slightly on the power supply voltage (see Table 3). The clock feedthrough specifications are not part of the wideband noise.

Aliasing Aliasing is an inherent phenomenon of sampled data systems and occurs for input frequencies approaching the sampling frequency. The internal sampling frequency of the LTC1069-6 is 100 times its cutoff frequency. For instance, if a 98.5kHz, 100mVRMS signal is applied at the input of an LTC1069-6 operating with a 50kHz clock, a 1.5kHz, 484VRMS alias signal will appear at the filter output. Table 4 shows details.
