The ISL28470 is available immediately in a 28-Lead QSOP
package and is priced at USD2.33 each in 1,000-unit quantities.
IPAs can generally be found in two categories of packaging: MMICs, using plastic packages (QSOP
, MLP, for example) and usually with integrated heatsink/exposed ground area; or hybrid modules with matching components integrated, possibly containing several chips of different technologies.
IPD's integrate multiple passive components into a single package; for example CAMD's P/Active(R) Super1284(TM) combines 42 discrete passive components and 17 electrostatic protection devices in a single 28-pin QSOP

Texas Instruments manufactures the SN74CBTT3253 device in the 16-pin QSOP
, SOIC, TSSOP and TVSOP packages.
Body style options include narrow and wide SOIC, QSOP
and 0.6, 0.5 or 0.4 die packs.
They are available in 16-pin and 24-pin QSOP
. Prices start at $2.35 each in 10,000-piece quantities.
All three of these low cost ICs operate from a 3 V power supply and are provided in small QSOP
The A3935 is supplied in either a 44- lead plastic PLCC with four copper batwing tabs for maximum heat dissipation or in a 36-lead QSOP
The 24-lead quality small outline package (QSOP
) industry-standard plastic package occupies the same PCB area (0.080 sq.
