HTS 10-P Current Transducer
The HTS 10-P provides electronic measurement of AC,
DC, pulsed, and complex currents with galvanic
isolation between the primary (power) circuit and the
secondary (measurement) circuit.

Output Reference
A positive going output signal is obtained when
the primary current flows from the I+ to I- pin.
Notes:
1) This device is ratiometric: sensitivity and offset vary in direct proportion to supply voltage.
2) Output linearity is not guaranteed within 500mV of the supply rails.
3) Output loading to V

Dimensions for the HTS 10-P in millimeters
(1mm = 0.0394")
:
Notes:
A positive going output signal is obtained when the primary current flows from I+ to I-.
Primary wires may also be used through the aperture. Sensitivity is reduced by a factor of 3.
A positive going output signal is obtained when the primary current flows from bottom to top.
Optimum performance is attained with a 0.1F capacitor between V
DD
and V
SS
and a 100pF
capacitor between O
UT
to V
SS
, placed as close to the HTS 10-P pins as possible.
Recommended PWB hole diameters: 2 x 1.3 for primary, 3 x 0.8 for secondary.
This device is sensitive to electrostatic discharge (ESD) and must be handled appropriately.
