Microchip expands zero-drift operational amplifier portfolio for signal conditioning, instrumentation and portable sensor applications

Microchip has broadened its portfolio of zero-drift operational amplifiers (op amps) with the debut of the MCP6V11 and MCP6V31 single amplifiers.  Operating with a single supply voltage as low as 1.6V and a quiescent current as low as 7.5 µA, these ultra-high-performance devices offer some of the industry’s lowest quiescent current for the given bandwidth without sacrificing the optimal performance essential for portable applications in the consumer, industrial and medical markets.

With an ageing world population in need of new therapies and early diagnostic tools, devices such as the MCP6V11/31 enable the development of portable medical products integrated with higher efficiency, and signal-conditioning hardware and software, which is critical to accommodate the continued push for lower costs and faster times to market.  In addition, designers of industrial applications such as portable sensor conditioning and instrumentation which require low power, smaller form factors, simplified thermal management and cost control, can benefit from the optimised performance, low quiescent current and low operating voltage made possible by the MCP6V11/31 op amps.

Employing Microchip’s advanced CMOS technology, the devices require less current to operate the amplifier whilst simultaneously delivering longer battery life and minimal thermal-related challenges.  The self-correcting architecture of the MCP6V11/31 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.  Additionally, the MCP6V11 and MCP6V31 single amplifiers are both available in small 5-pin SOT-23 and 5-pin SC-70 packages, enabling minimal use of board space, ease of system design and reduced cost.
