Unique, dual-connected op amp enables two stages in one chip

Chandler, AZ — Microchip Technology Inc., a provider of microcontroller and analog semiconductors offers an innovative analog device for the digital environment. These devices enable a standard two-stage amplifier signal chain to be implemented into an eight-lead package with a power-saving chip select. The internal connection of the two stages enables one operational amplifier to feed into the other making a more compact design.

Microchip's MCP62x5 devices are extended industrial-temperature range (-40 degrees C to 125 degrees C), Rail-to-Rail input/output (I/O), single-ended operational amplifiers. Covering the 2 MHz, 5 MHz and 10 MHz Gain Bandwidth Product (GBWP), these devices allow for the most current flow efficient design by having low supply-current requirements. With a migration path along the GBWP spectrum, designers can optimize the GBWP to be selected for the current flow versus GBWP demand for the application.

These devices are ideal for sensor, automotive, instrumentation, industrial and battery-operated applications. The MCP6275 has a 2 MHz-gain bandwidth and operates at 5.5V to 2.0V with a supply current of 165 microamps. Meanwhile, the MCP6285 has a 5 MHz-gain bandwidth, operates at 5.5V to 2.2V and has a supply current of 450 microamps. The MCP6295 has a 10 MHz-gain bandwidth, operates at 5.5V to 2.4V and has a supply current of 1.0 milliamps.

Pricing in 1,000-unit quantities in the MSOP package is $0.58 each for the MCP6275, $0.65 each for the MCP6285 and $0.71 each for the MCP6295. These devices are also available in an 8-pin, PDIP and SOIC packages. Samples are available now and volume production is scheduled for July 2004.
