What are the key features of MCP6273-E/SN?
- Single-channel 2 MHz gain-bandwidth product operational amplifier with voltage-feedback architecture for precision signal conditioning
- Ultra-low 5 nA average bias current and 65 dB minimum common-mode rejection ratio (85 dB typical) for accurate low-frequency measurement
- Chip select (CS) enable pin allows power-down control, reducing supply current in multi-channel systems with duty-cycled analog front ends
What is MCP6273-E/SN used for?
The MCP6273-E/SN is used in precision low-frequency signal conditioning, sensor interface circuits, and portable battery-powered instrumentation where ultra-low bias current and a chip select power-down function are required. Its 2 MHz bandwidth and 85 dB typical CMRR make it suitable for active filter stages, data acquisition front ends, and transimpedance amplifiers driving 12-bit or 16-bit ADCs. The compact SOIC-8 package fits standard PCB layouts in industrial and consumer measurement devices.

Frequently Asked Questions
How does the MCP6273-E/SN chip select pin reduce power consumption in multi-channel analog front ends?
The MCP6273-E/SN chip select (CS) pin places the op-amp into a low-power shutdown state, cutting quiescent current from the active value to microamp levels. In a system cycling multiple sensor channels, toggling CS between conversions on a 2 MHz bandwidth op-amp can reduce average supply current by over 90% compared to leaving it continuously active, extending battery life in handheld instruments.
What ADC resolution does the MCP6273-E/SN CMRR spec support in differential sensor measurement circuits?
With a 65 dB minimum and 85 dB typical common-mode rejection ratio, the MCP6273-E/SN suppresses common-mode noise well enough to support 12-bit to 14-bit ADC resolution in differential sensor inputs. At 5 V supply, 65 dB CMRR limits common-mode error to approximately 1.4 mV from a 5 V common-mode input, which stays within the LSB budget of a 12-bit converter with a 5 V reference.
Is MCP6273-E/SN a suitable replacement for MCP6271-E/SN in an existing SOIC-8 PCB layout?
The MCP6273 adds a chip select pin not present on the MCP6271, so the two are not pin-for-pin compatible in all respects. Both share the same 2 MHz gain-bandwidth product and SOIC-8 footprint, but the MCP6273's CS pin requires a logic-level drive on the corresponding pin. If CS is tied to VDD (logic high, always-on), the MCP6273-E/SN operates like the MCP6271, allowing a drop-in board substitution with an added pull-up resistor of 10 kΩ or less.
