MCP6C26T-100E/LTY

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6C26T-100E/LTY is a single-channel, zero-drift current sense amplifier manufactured by Microchip Technology. It features a fixed differential-mode gain of 100 V/V and operates within a supply voltage range of 2.7V to 5.5V. The device supports both unidirectional and bidirectional current sensing with an input common-mode voltage range specified from -0.2V to +36V. Key electrical characteristics include a typical input offset voltage of ±15 µV, a typical common-mode rejection ratio (CMRR) of 123 dB, and a typical power supply rejection ratio (PSRR) of 131 dB. The bandwidth is typically 90 kHz, with a quiescent current of approximately 65 µA. It is housed in a compact SC-70 package and is rated for operation over an extended temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'LTY' corresponds to the SC-70 tape-and-reel packaging configuration as defined in the product identification system. Confirm that the 'E' designation indicates the extended temperature rating (-40°C to +125°C). Ensure the ordering part number matches the required 100 V/V gain variant, distinct from the 50 or 200 V/V options available in the family.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits requiring high accuracy in current monitoring where shunt resistor power dissipation must be minimized due to low offset voltage. The 100 V/V gain is suitable for applications needing moderate signal amplification without excessive bandwidth reduction compared to the 200 V/V variant. Consider the SC-70 package size constraints and the requirement for a reference voltage pin (VREF) for output level shifting in single-supply designs.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MCP6C26 family of zero-drift current sense amplifiers. The family differentiates primarily by preset differential gains of 50, 100, and 200 V/V. All variants share the same core architecture, including the wide common-mode input range, low supply current, and SC-70 packaging. The MCP6C26T-100E/LTY specifically denotes the 100 V/V gain version in the extended temperature grade with reel packaging.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same family include MCP6C26T-050E/LTY (50 V/V gain) and MCP6C26T-200E/LTY (200 V/V gain), provided the gain difference is acceptable for the application circuit design.
