PIN FUNCTIONS
CLKIO (Pin 15): When CLKCNTL (Pin 5) is tied to ground,
CLKIOisthemasterclockinput.WhenCLKCNTLisfloated,
CLKIO is pulled to ground by a weak, 5A pulldown. When
CLKCNTL is tied to V+D(Pin16),CLKIOisthemasterclock
output. When configured as a clock output, this pin can
drive 1k and/or 5pF loads. Heavier loads may cause inac-
curacies due to supply bounce at high frequencies.
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 0.1F
capacitor. The bypass should be as close as possible to
the IC.
SER (Pin 17): Interface Selection Input. When tied to V+D
(Pin16),theinterfaceisinpinprogrammablecontrolmode,
i.e. the filter gain and cutoff frequencies are programmed
by the GAIN1, GAIN0, HPF1, HPF0, LPF1 and LPF0 pin
connections. When SER is tied to ground, the filter gain,
the filter cutoff frequencies and shutdown mode are pro-
grammed 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 100
Ω series resistor
is recommended for each output. The common mode
voltage of the filter outputs is the same as the voltage at
VOCM (Pin 3).
MUTE (Pin 20): MUTEX input. Drive to ground to discon-
nect and mute the inputs. Float or drive to V+D (Pin 16)
for normal operation.
GAIN0(D0) (Pin 21): Logic Input. When in pin program-
mable 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): Logic 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 voltage levels can
range from GND to the V+IN supply rail.
Exposed Pad (Pin 25): Ground. The Exposed Pad must
be soldered to PCB.
