TLC4502MD

Instrumentation, Op Amps, Buffer Amps Overview

The TLC4502MD is a dual precision CMOS operational amplifier featuring Self-Cal technology. It operates within a supply voltage range of 4 V to 6 V and supports an operating temperature range from -55°C to 125°C. The device achieves a maximum input offset voltage of 100 µV with a typical drift of 1 µV/°C. Key electrical characteristics include a gain-bandwidth product of 4.7 MHz, a slew rate of 2.5 V/µs, and high output drive capability of ±50 mA per channel.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Self-calibrating circuitry digitally trims input offset voltage to less than 100 µV within the first 300 ms of operation.
• Rail-to-rail output voltage swing capability for single-supply applications.
• High output drive capability supporting capacitive loads up to 1000 pF without instability.
• Low input bias current of 1 nA at 25°C minimizes loading effects on high-impedance sources.

Instrumentation, Op Amps, Buffer Amps Applications

• Data acquisition systems requiring high precision.
• Measurement equipment utilizing low-noise amplification.
• Industrial control applications demanding wide temperature stability.
• Portable digital scales needing accurate signal conditioning.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'M' indicates the military-grade temperature range (-55°C to 125°C) and 100 µV max offset. Confirm package availability matches design requirements, as this part is available in D (SOIC), FK (Chip Carrier), JG (Ceramic DIP), and U (Flat Pack). Ensure calibration time constraints are compatible with system power-on sequences.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the TLC4502MD when extended temperature performance and higher offset voltage tolerance (100 µV) are acceptable alternatives to the tighter 40 µV variants. This model offers robust industrial reliability with rail-to-rail outputs. Consider the physical package dimensions for FK, JG, or U options if through-hole or chip carrier mounting is required instead of standard surface mount.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the TLC450x family of self-calibrating precision amplifiers. It shares architectural similarities with the TLC4501 (single channel) and TLC4502A (tighter offset specs). The 'M' suffix specifically denotes the extended military temperature range and distinct offset specifications compared to the commercial 'C' or industrial 'I' grades.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the self-calibration process affect initial startup?

Upon power-up, the internal calibration circuitry activates for approximately 300 ms to trim the offset voltage. During this period, the device functions as a calibrator before switching to standard operational amplifier mode.

What is the maximum capacitive load supported?

The device is stable driving capacitive loads up to 1000 pF, ensuring reliable operation in filtering and buffering applications without external compensation components.
