Op amps deliver high precision, low-power operation in tiny package

Microchip Technology Inc. has broadened its portfolio of zero-drift operational amplifiers with the debut of the MCP6V11 and MCP6V31 single amplifiers. 

The MCP6V11 and MCP6V31 op amps operate with a single supply voltage as low as 1.6V and a quiescent current as low as 7.5 µA. They are aimed at portable applications in the consumer, industrial and medical markets.

Employing Microchip'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 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.

Pricing: For the MCP6V11 starts at $0.82 each in 5,000-unit quantities, while the MCP6V31 starts at $0.81 each.
