can be configured as an on-chip oscillator, as
shown in Figure 8. The oscillator circuit is designed
to work with a quartz crystal or a ceramic resona-
tor. To reduce circuit cost, two load capacitors C1
and C2 are integrated in the device, one between
XIN and DGND, one between XOUT and DGND.
Lead lengths should be minimized to reduce stray
capacitance. To drive the device from an external
clock source, XOUT should be left unconnected
while XIN is driven by the external circuitry. There
is an amplifier between XIN and the digital section
which provides CMOS level signals. This amplifier
works with sinusoidal inputs so there are no prob-
lems with slow edge times.

By directly connecting FREQ with P4 and IGAIN
with P5 the CS5462 is configured to drive a step-
per motor with a maximum pulse output rate of
2 Hz, to support an input range of 500 mV P-P , and
to remove all DC content on the current signals by
enabling the HPFs on the Ich. The CS5462 is now
ready for calibration.
Before applying power to the chip, connect the
CAL0 and CAL1 pins to P4. This will select
0% + 0% = 0% gain adjustment. After making this
connection the CS5462 is ready to be calibrated.
Once power is applied the CS5462 will begin a
startup sequence in which it will scan the FREQ,
IGAIN, CAL0, and CAL1 pins. After determining
which connections are made the FREQ, IGAIN,

CAL0, and CAL1 pins will become high impedance
inputs and the part will begin normal operation and
start converting. If on-chip calibration is required
place known voltages across the inputs on IIN±
and VIN±.
For example, 150 mV RMS = ~424.26 mV P-P will be
used for both the current and voltage inputs.
424.26 mV P-P is ~84.853% of the maximum full
scale input of both the current and voltage chan-
nels. With this input on both channels the expected
