PIN FUNCTIONS
UU
U
IN +/IN – (Pins 1, 2): Signals can be applied to either or
both input pins. The DC gain from IN + (Pin 1) to OUT
(Pin 8) is 1.0, and the DC gain from Pin 2 to Pin 8 is –1. The
input range, input resistance and output range are de-
scribed in the Applications Information section. Input
voltages which exceed the power supply voltages should
be avoided. Transients will not cause latchup if the current
into/out of the input pins is limited to 20mA.
GND (Pin 3): The GND pin is the reference voltage for the
filter and should be externally biased to 2V (1.11V) to
maximize the dynamic range of the filter in applications
using a single 5V (3V) supply. For single supply operation,
the GND pin should be bypassed with a quality 1
F
ceramic capacitor to V – (Pin 4). The impedance of the
circuit biasing the GND pin should be less than 2k
as the
GND pin generates a small amount of AC and DC current.
For dual supply operation, connect Pin 3 to a high quality
DC ground. A ground plane should be used. A poor ground
will increase DC offset, clock feedthrough, noise and
distortion.
V –/V + (Pins 4, 7): For 3V, 5V and
±5V applications a
quality 1
F ceramic bypass capacitor is required from V+
(Pin 7) to V – (Pin 4) to provide the transient energy for the
internal clock drivers. The bypass should be as close as
possible to the IC. In dual supply applications (Pin 3 is
grounded), an additional 0.1
F bypass from V+ (Pin 7) to
GND (Pin 3) and V – (Pin 4) to GND (Pin 3) is recom-
mended.
The maximum voltage difference between GND (Pin 3) and
V + (Pin 7) should not exceed 5.5V.
DIV/CLK (Pin 5): DIV/CLK serves two functions. When the
internal oscillator is enabled, DIV/CLK can be used to
engage an internal divider. The internal divider is set to 1:1
when DIV/CLK is shorted to V – (Pin 4). The internal divider
is set to 4:1 when DIV/CLK is allowed to float (a 100pF
bypass to V – is recommended). The internal divider is set
to 16:1 when DIV/CLK is shorted to V + (Pin 7). In the
divide-by-4 and divide-by-16 modes the power supply
current is reduced by as much as 40%.
When the internal oscillator is disabled (RX shorted
to V –) DIV/CLK becomes an input pin for applying an
external clock signal. For proper filter operation, the clock
waveform should be a squarewave with a duty cycle as
close as possible to 50% and CMOS voltages levels (see
Electrical Characteristics section for voltage levels). DIV/
CLK pin voltages which exceed the power supply voltages
should be avoided. Transients will not cause latchup if the
fault current into/out of the DIV/CLK pin is limited to 40mA.
RX (Pin 6): Connecting an external resistor between the RX
pin and V + (Pin 7) enables the internal oscillator. The value
of the resistor determines the frequency of oscillation. The
maximum recommended resistor value is 40k and the
minimum is 3.8k. The internal oscillator is disabled by
shorting the RX pin to V – (Pin 4). (Please refer to the
Applications Information section.)
OUT (Pin 8): Filter Output. This pin can drive 10k
and/or
40pF loads. For larger capacitive loads, an external 100
series resistor is recommended. The output pin can ex-
ceed the power supply voltages by up to
±2V without
latchup.
