PIN FUNCTIONS
LPF1(CS) (Pin 6): TTL Level Input. When in pin program-
mable control mode, this pin is the MSB of the lowpass
cutoff frequency control code; in serial control mode, this
pin is the chip select input (active low).
+INB, –INB (Pins 7, 8): Channel B Differential Inputs.
The input range and input resistance are described in the
Applications Information section. Input voltages which
exceed V+IN (Pin 1) should be avoided.
LPF0 (SCLK) (Pin 9): TTL Level Input. When in pin pro-
grammable control mode, this pin is the LSB of the lowpass
cutoff frequency control code; in serial control mode, this
pin is the clock of the serial interface.
SDI (Pin 10): TTL Level Input. When in pin programmable
control mode, this pin is left oating; in serial control
mode, this pin is the serial data input.
SDO (Pin 11): TTL Level Input. When in pin programmable
control mode, this pin is left oating; in serial control
mode, this pin is the serial data output.
–OUTB, +OUTB (Pins 12, 13): Channel B Differential Filter
Outputs. These pins can drive 1k and/or 50pF loads. For
larger capacitive loads, an external 100Ω series resistor
is recommended for each output. The common mode
voltage of the lter outputs is the same as the voltage at
VOCM (Pin 3).
GND (Pin 14): Ground. Should be tied to a ground plane
for best performance.
CLKIO (Pin 15): When CLKCNTL (Pin 5) is tied to ground,
CLKIO is the master clock input. When CLKCNTL is oated,
CLKIO is pulled to ground by a weak pulldown. When
CLKCNTL is tied to V+D (Pin 16), CLKIO is the master
clock output. When congured as a clock output, this pin
can drive 1k and/or 5pF loads (heavier loads will cause
inaccuracies).
V+D (Pin 16): Digital Voltage Supply (2.7V ≤ V ≤ 3.6V).
This supply must be kept free from noise and ripple. It
should be bypassed directly to a ground plane with a 0.1μF
capacitor. The bypass should be as close as possible to
the IC.
SER (Pin 17): Interface Selection Input. When tied to V+D
(Pin 16) or oated, the interface is in pin programmable
control mode, i.e. the lter gain and cutoff frequencies
are programmed by the GAIN1, GAIN0, LPF1 and LPF0
pins. When SER is tied to ground, the lter gain, the lter
cutoff frequency and shutdown mode are programmed
by the serial interface.
–OUTA, +OUTA (Pins 18, 19): Channel A Differential Filter
Outputs. These pins can drive 1k and/or 50pF loads. For
larger capacitive loads, an external 100Ω series resistor
is recommended for each output. The common mode
voltage of the lter outputs is the same as the voltage at
VOCM (Pin 3).
CAP (Pin 20): Connect a 0.1μF bypass capacitor to this
pin. Pin 20 is a buffered version of Pin 3.
GAIN0(D0) (Pin 21): TTL Level Input. When in pin pro-
grammable control mode, this pin is the LSB of the gain
control code; in serial control mode, this pin is the LSB
of the serial control register, an output.
GAIN1 (Pin 22): TTL Level Input. When in pin programmable
control mode, this pin is the MSB of the gain control code;
in serial control mode, this pin is a no-connect.
–INA, +INA (Pins 23, 24): Channel A Differential Inputs.
The input range and input resistance are described in the
Applications Information section. Input voltages which
exceed V+IN (Pin 1) should be avoided.
Exposed Pad (Pin 25): Ground. The Exposed Pad must
be soldered to PCB.
