Each BiCMOS monolithic circuit integrates a Hall element,
temperature-compensatingcircuitrytoreducetheintrinsicsensitivity
driftoftheHallelement,asmall-signalhigh-gainamplifier,aclamped
low-impedance output stage, and a proprietary dynamic
offset cancellation technique.
The A138x devices are provided in a 3 pin ultramini single-in-line
package (UA suffix), and a 3 pin surface mount SOT-23W package
(LH suffix).
