Microchip Technology Inc. (Chandler, AZ) introduced a family of 1MHz operational amplifiers that reduce supply voltage demand, making them suitable for extending battery life and other low-voltage applications. The MCP6001, MCP6002 and MCP6004 devices, which offer rail-to-rail input/output and have a 90-degree phase margin into a 60, 10kohm load, provide stability in a low-cost operational amplifier.
Low-voltage operation reduces the need for voltage doubler circuitry, and low quiescent current of 100µ:A further lessens demand on the battery. The new devices feature typical power usage of 180µW, making the op amps suitable for use in sensors, instrumentation devices, consumer products, battery-operated applications and devices powered by a single communication loop.
Pricing in 1,000-unit quantities is $0.25 each for the single MCP6001, $0.30 for the dual MCP6002 and $0.35 for the quad MCP6004. Samples and volume quantities are now available. The MCP6001 is available in SOT-23 and SC-70 packages. The MCP6002 is available in PDIP, SOIC and MSOP packages. The MCP6004 is available in PDIP, SOIC and TSSOP packages.
