MCP652-E/SN

Instrumentation, Op Amps, Buffer Amps Overview

The MCP652-E/SN is a dual-channel operational amplifier from the Microchip MCP65X family, featuring a 50 MHz gain-bandwidth product and a 30 V/µs slew rate. It incorporates internal mCal self-calibration to achieve a maximum input offset voltage of ±200 µV after power-up or calibration trigger. The device operates on a single supply voltage ranging from +2.5V to +5.5V, drawing 6.0 mA per channel in normal mode and 5 µA per channel in low-power mode. It offers rail-to-rail output swing, an input range including the negative rail, and high output current capability of ±100 mA.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Internal mCal self-calibration mechanism reduces input offset voltage to ±200 µmV at power-up or upon CAL/CS pin activation
• Rail-to-rail output with input common-mode range extending to the negative supply rail
• Low-power mode operation accessible via CAL/CS pin for significant quiescent current reduction
• High-speed performance with 50 MHz gain-bandwidth product and 30 V/µs slew rate

Instrumentation, Op Amps, Buffer Amps Applications

• Driving A/D converters
• Fast low-side current sensing
• Power amplifier control loops
• Optical detector amplifiers
• Multi-pole active filters

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'E' indicates extended temperature range (-40°C to +125°C) and 'SN' denotes the SOIC-8 package. Confirm that the datasheet DS20002146D applies to this part number as it covers the MCP651/1S/2/3/4/5/9 family. Ensure the application circuit matches the required gain and load conditions specified in the electrical characteristics table.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high bandwidth and low offset are required in a dual-channel configuration. The inclusion of the CAL/CS pin allows for dynamic low-power switching, making it suitable for battery-operated systems requiring periodic high-speed bursts. Compare against the MCP651 (single channel) or MCP654 (quad channel) if channel count differs. Verify that the 6.0 mA quiescent current fits the thermal budget compared to lower-speed alternatives like the MCP602.

Instrumentation, Op Amps, Buffer Amps Part Context

The MCP652 belongs to the MCP65X series of high-speed, low-offset operational amplifiers manufactured by Microchip Technology. This family is characterized by its use of internal calibration circuits to minimize drift and offset errors without external components. The dual-channel variant provides two independent amplifiers in a compact footprint, sharing the same core architecture as the single and quad versions within the MCP651 through MCP659 lineup.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same family include MCP651 (single channel) and MCP654 (quad channel). For pin-compatible replacements with different channel counts, consider MCP651 or MCP654 depending on design flexibility. Cross-family comparisons should account for differences in GBWP and offset specifications.
