A3425
Ultra-Sensitive Dual-Channel Quadrature
Hall-Effect Bipolar Switch
Description (continued)
quadrature. The patented chopper stabilization technique cancels
offsets in each channel, and provides stable operation over the
operating temperature and voltage ranges. An on-chip regulator
allows the use of this device over a wide operating voltage range.
Post-assembly factory programming provides sensitive switchpoints
that are symmetrical between the two switches.
The A3425 is available in a plastic 8-pin SOIC surface mount
package (L) and a plastic 4-pin SIP (K), both in two operating
temperature ranges. Each package is available in a lead (Pb) free
version with 100% matte tin plated leadframe.

1Pb-based variants are being phased out of the product line. The variants cited in this footnote are in production but have been determined to
be NOT FOR NEW DESIGN. This classification indicates that sale of this device is currently restricted to existing customer applications. The
variants should not be purchased for new design applications because obsolescence in the near future is probable. Samples are no longer
available. Status change: May 1, 2006. These variants include: A3425EL, A3425ELTR, A3425LL, and A3425LLTR.
