*Contact Allegro for additional packing and operating temperature range options

generator, small-signal amplifier, chopper stabilization, a latch,

and a MOSFET output. Advanced BiCMOS processing is used

to take advantage of low-voltage and low-power requirements,

component matching, very low input-offset errors, and small

component geometries.

Devices are rated for operation over a temperature range of

–40°C to 85°C or –40°C to 150°C. Two package styles provide a

magnetically optimized package for most applications. ‘LH’ is a

miniature low-profile surface-mount package, ‘UA’ is a three-lead

SIP for through-hole mounting. Each package is lead (Pb) free

(suffix, –T) , with a 100% matte tin plated leadframe.
