MICROCHIP Technology has unveiled three operational amplifier (op amp) families featuring extended industrial temperature range (-40ºC to +125ºC) and input/output rail-to-rail functionality.

These are general-purpose op amps, which are suitable for many diverse markets, specifically in automotive, industrial and other appliances where higher temperature is expected.

These multiple gain bandwidth product (GBWP) op amps have a low-supply current requirement, which enables an efficient current-flow design.

With an offering at 2, 5 and 10MHz GBWP, engineers have a migration path to maximise their designs for best bandwidth vs. supply current.

This path along the GBWP spectrum is available for amplifiers with the same general performance, making it easier to change or improve designs.

Designed with Microchip's advanced CMOS process, the new op amp families provide a wide bandwidth for current. In addition, they support both input and output rail-to-rail swing.

Microchip's MCP6271/2/3/4 family has a 2MHz gain bandwidth and a 65 degree phase margin. It operates from a single-supply voltage as low as 2.0V, while drawing a 170μA (typical) quiescent current at 5.5V.

The MCP6281/2/3/4 family has a 5MHz gain bandwidth and 65 degree phase margin. This family operates from a single-supply voltage as low as 2.2V, while drawing 450μA (typical) quiescent current at 5.5V.

Microchip's MCP6291/2/3/4 family has a 10MHz gain bandwidth product and 65 degree phase margin. This family operates from a single-supply voltage as low as 2.4V, while drawing 1mA (typical) quiescent current at 5.5V.

These devices are available in PDIP, SOIC, MSOP and TSSOP packaging and offer single, single with chip select, dual and quad amplifiers.
