Op amp has wide supply voltage range of 5 to 40V, output current limit of 3.0A and slew rate of 1.2V/ps. Applications include half and full bridge motor drivers, audio power amplifier, single supply systems, and bi-directional motor controllers.Original Press Release:
Apex Announces The PA37; A Low Cost, High Voltage, Surface-Mount Amplifier
Apex Microtechnology introduces the PA37, the newest addition to the Apex Power Operational Amplifier product line. Joining Apex's PA21, PA25 and the PA26; the PA37 was developed to fulfill market needs for a true surface-mounted product. The PA37 consists of a monolithic dual power op amp in a 24-pin PSOP package. Featuring two power op amps in one package and on one-die results in an extremely cost effective solution for applications requiring multiple amplifiers per board, parallel operation or bridge mode configuration.
The PA37 is a product that can be automatically inserted onto FR-4 boards using a copper-slug as a solder connection for heat-dissipation. In addition to a wide supply voltage range (single supply: 5V to 40V, split supplies: ±2.5V to ±20V), the PA37 has an output current limit of 3.0A and a slew rate of 1.2V/ps. The PA37 can also operate on a single power supply. At a $10K price of $4.15 the PA37 will interest anyone who wants to supply high power on a surface mount process at a low cost.
