MCP6042T-I/SN Microchip Operational Amplifier 2 Circuit Rail-to-Rail 8-SOIC
The MCP6042T-I/SN is a dual-channel, general-purpose operational amplifier (op-amp) manufactured by Microchip Technology, designed for low-power, battery-operated applications. Featuring a rail-to-rail input and output (RRO) architecture, it operates across a wide supply voltage range of 1.4V to 6V, making it ideal for portable devices, sensor interfaces, and low-frequency signal conditioning. The device achieves ultra-low quiescent current of 600nA per channel (typical) while maintaining a unity-gain stable configuration with a gain bandwidth product (GBP) of 14kHz. Its SOIC-8 package ensures compact integration into surface-mount designs, and the -40°C to +85°C operating temperature range supports industrial and consumer electronics use cases. Key applications include battery current monitoring, medical instrumentation, and wearable technology, where minimal power consumption and high accuracy are critical.
Technical Specifications
The MCP6042T-I/SN integrates two independent op-amp channels, each delivering a slew rate of 0.003V/µs and an output current capacity of 20mA per channel. It features an input bias current of 1pA and an input offset voltage of ±3mV, ensuring low distortion and high linearity in precision circuits. The amplifier’s common-mode rejection ratio (CMRR) is 60dB, while its power supply rejection ratio (PSRR) reaches 85dB, enabling robust performance in noisy environments. The device supports single-supply operation, eliminating the need for dual-voltage rails, and its MSL1 moisture sensitivity rating ensures long-term reliability during storage and assembly. The SOIC-8 package dimensions (4.9mm length × 3.9mm width) and 1.25mm height facilitate automated PCB assembly, with RoHS3 and REACH compliance meeting global environmental standards.
