Texas Instruments TLC27M7CP

Overview

TLC27M7CP from Texas Instruments is a dual precision LinCMOS operational amplifier with 500 µV max input offset voltage at 25°C, rail-to-rail output swing (includes negative rail), and operation from 3 V to 16 V supply across 0°C to 70°C. It delivers low noise (32 nV/√Hz @ 1 kHz), high input impedance (10¹² Ω), and low power (2.1 mW typ @ 5 V), enabling use in battery-powered sensor signal conditioning and precision analog front-ends.

For engineers reviewing the TLC27M7CP datasheet, TLC27M7CP pinout, TLC27M7CP application, or TLC27M7CP equivalent, this page provides verified package mapping (8-pin PDIP), confirmed dual-opamp circuit role, exact offset voltage grade (500 µV), temperature range (0°C to 70°C), and validated alternatives for precision low-power analog designs.

Technical Context

The TLC27M7CP uses silicon-gate LinCMOS process technology to achieve stable offset voltage drift (0.1 µV/month) and latch-up immunity, distinguishing it from metal-gate CMOS op-amps. Its input stage extends common-mode range below the negative rail, supporting true single-supply operation without level-shifting circuitry.

Each amplifier features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), surge-current tolerance (±100 mA), and designed-in robustness against input overvoltage. The device exhibits 525 kHz unity-gain bandwidth and 40° phase margin at 5 V, ensuring stable closed-loop performance in active filters and transducer interfaces.

FAQ

What is the maximum input offset voltage specification for TLC27M7CP at 25°C?

The maximum input offset voltage for TLC27M7CP is 500 µV at 25°C, as specified in the "Available Options" table and confirmed in the Electrical Characteristics section (VDD = 5 V, TA = 25°C). This value defines the worst-case DC error at room temperature before trimming and is the key differentiator between the TLC27M7 (precision grade) and lower-grade variants like TLC27M2.

Does TLC27M7CP support true single-supply operation with inputs referenced to ground?

Yes, TLC27M7CP supports true single-supply operation: its common-mode input voltage range extends to −0.2 V below GND at VDD = 5 V, and the output swings fully to the negative rail. This allows direct connection of grounded-sensor outputs (e.g., bridge circuits) without level-shifting components-verified in the Recommended Operating Conditions and Electrical Characteristics tables.

What package type is used for the TLC27M7CP part number?

TLC27M7CP uses the 8-pin plastic DIP (dual in-line package), designated "P" in TI's packaging nomenclature. This through-hole package has 0.3-inch body width, 0.1-inch pin spacing, and is JEDEC MS-001 compliant-explicitly listed in the "AVAILABLE OPTIONS" table alongside "TLC27M7CP" under the "PLASTIC DIP (P)" column.

How does the input bias current of TLC27M7CP compare to bipolar op-amps?

TLC27M7CP exhibits typical input bias current of 0.6 pA at 25°C-six orders of magnitude lower than typical bipolar op-amps (e.g., LM741: ~80 nA). This ultra-low bias current, enabled by LinCMOS technology, prevents significant voltage errors across high-impedance sources (e.g., >1 MΩ feedback networks or pH electrodes), making it suitable for precision measurement front-ends where bipolar devices would introduce unacceptable offsets.

Is TLC27M7CP pin-compatible with other devices in the TLC27Mx family?

Yes, all TLC27Mx dual op-amps-including TLC27M2, TLC27M7, and their C/I/M suffix variants-are fully pin-compatible in the same package (e.g., P, D, PW). The TLC27M7CP shares identical pinout, supply connections, and terminal functions with TLC27M2CP and TLC27M7ID, allowing direct substitution in existing layouts when upgrading offset performance without hardware changes.
