Frequently Asked Questions
What is the gain-bandwidth product of the MCP6L91T-E/OT, and how does it affect signal fidelity at higher frequencies?
The MCP6L91T-E/OT has a 10 MHz gain-bandwidth product, meaning at a closed-loop gain of 10, the usable bandwidth is approximately 1 MHz. This makes it suitable for audio and instrumentation circuits requiring accurate signal reproduction up to several hundred kilohertz while keeping phase margin adequate for stable operation.
Which industrial sensor applications benefit most from the MCP6L91T-E/OT's 91 dB common-mode rejection ratio?
Applications such as thermocouple amplifiers, strain gauge bridges, and 4–20 mA current-loop receivers benefit greatly from the 91 dB CMRR. This high rejection level attenuates common-mode noise by over 35,000:1, preserving signal integrity in electrically noisy industrial environments where ground potential differences of several hundred millivolts are common.
How does the SOT-23-5 package of the MCP6L91T-E/OT support compact PCB designs compared to larger op-amp packages?
The SOT-23-5 package measures approximately 2.9 mm × 1.6 mm, occupying less than 5 mm² of PCB area, which is roughly 80% smaller than an SOIC-8 footprint. This enables denser layouts in handheld instruments, wearables, and IoT sensor nodes where board real estate is limited and a single-channel op-amp per stage is preferred.
What is the maximum input offset voltage of the MCP6L91T-E/OT, and when does it matter in precision circuits?
The maximum input offset voltage is 4000 µV (4 mV). In precision DC measurement circuits with gains above 100, this offset would introduce up to 400 mV of output error, so external trimming or auto-zeroing techniques should be applied. For AC-coupled or lower-gain stages the offset impact is minimal.
