Auto-Zero Operational Amplifier

Microchip Technology Inc announced the MCP6V2X family of operational amplifiers (op amps). The new devices feature a self-correcting auto-zero architecture, which enables ultra-high precision, including an input offset voltage of just 2 microvolts and a gain bandwidth product of 2 MHz. With low noise of 50 nV/root Hz, the MCP6V2X family is a lower-noise alternative to Microchip's existing family of auto-zero op amps. Their low 2.3V to 5.5V operating voltage allows batteries to be fully utilized, and their rail-to-rail input/output structure allows for full-range use, even in low-supply conditions. The devices are available in a compact, 8-pin MSOP package, and are ideal for applications in the consumer, industrial and medical markets, such as sensor and signal conditioning and instrumentation.

Applications that require low noise, low-voltage operation, ultra-high precision and low drift can benefit from the performance and features of the MCP6V2X family. With their auto-zero architecture, the devices offer very high accuracy over time and temperature, and their lower noise provides for higher accuracy and repeatability. Additionally, the MCP6V2X family's low-voltage operation with rail-to-rail input/output enables greater dynamic range, which leads to better performance across the entire operating-voltage range.

The MCP6V26 is available in 8-pin SOIC, 8-pin MSOP and 2 mm x 3 mm 8-pin TDFN packages, for $1.13 each in 10,000-unit quantities. The MCP6V27 is available in 8-pin SOIC, 8-pin MSOP and 4 mm x 4 mm 8-pin DFN packages, for $1.73 each in 10,000-unit quantities. The MCP6V28 is available in 8-pin SOIC, 8-pin MSOP and 2 mm x 3 mm 8-pin TDFN packages, for $1.18 each in 10,000-unit quantities.
