TheA1308 andA1309 sensor ICs are offered in two package styles.

The LH is a SOT-23W style, miniature, low-profile package for

surface-mount applications. The UA is a 3-pin, ultramini, single

inline package (SIP) for through-hole mounting. Both packages are

lead (Pb) free, with 100% matte-tin leadframe plating.
