Tiny op-amps deliver high precision, low power

Tiny op-amps deliver high precision, low power

Suited for portable applications in the consumer, industrial and medical markets, the MCP6V11 and MCP6V31 zero-drift operational amplifiers operate with a single supply voltage as low as 1.6 V and a quiescent current as low as 7.5 µA. Based on the company’s advanced CMOS technology, the devices require less current to operate the amplifier while simultaneously delivering longer battery life and minimal thermal-related challenges.

The self-correcting architecture of the op-amp family provides a maximum input offset voltage of 8 µV for ultra-low-offset and low-offset drift, enabling maximum accuracy across time and temperature. The MCP6V11 offers 80 kHz of gain bandwidth product, with a low typical quiescent current of only 7.5 µA; while the MCP6V31 provides 300 kHz of gain bandwidth product, coupled with a low typical quiescent current of 23 µA.

These parts enable the development of portable medical products integrated with higher efficiency, and signal conditioning hardware and software. While designers of industrial applications — such as portable sensor conditioning and instrumentation requiring low power, smaller form factors, temperature considerations and cost-management — can benefit from the optimized performance, low quiescent current and low operating voltage.

Both the new MCP6V11 and MCP6V31 are in 5-pin SOT-23 and 5-pin SC-70 packages. (ea/5,000, MCP6V11, from $0.82;, MCP6V31, from $0.81 — available now)
