Microchip’s op amps extend battery life with exceptionally low power consumption

USA: Microchip Technology Inc. announced a new nine-member low-power, general-purpose operational amplifier (op amp) family—the MCP647X/8X/9X.

These op amps provide among the industry’s best power consumption for a given gain-bandwidth product, including low quiescent current, to extend battery lifetimes. Additionally, they have exceptionally low leakage current over temperature, up to 125°C, which reduces errors in applications such as sensor conditioning. In combination with features such as input offset voltage of 1.5 mV and space-saving packages as small as SC70 and SOT-23, these op amps are ideal for a broad range of portable applications in the consumer, industrial, automotive and medical markets.

The designers of portable, battery-powered applications are challenged to lower power consumption and reduce cost and board space without compromising on the robustness and accuracy of their signal chains. The MCP647X/8X/9X family of general-purpose op amps provides low supply current, low leakage current over temperature and low input offset voltage in small packages, which offers one of the industry’s best cost-to-performance ratios.

In fact, the 1.5 mV offset voltage offers better precision than the industry standard for general-purpose op amps, without the price premium of high-precision op amps. For applications that have sensors with high output impedance or that go through accelerated life tests at high temperatures, the MCP647X/8X/9X’s low leakage current is particularly important.
