Texas Instruments TLC27M7ID

Overview

TLC27M7ID from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, featuring 500 µV max input offset voltage at 25°C, −40°C to +85°C operating range, 32 nV/√Hz input noise at 1 kHz, and rail-to-rail output swing down to the negative rail. It serves as a low-power, high-impedance signal conditioning IC in sensor front-ends and battery-powered instrumentation.

For engineers reviewing the TLC27M7ID datasheet, TLC27M7ID pinout, TLC27M7ID application, or TLC27M7ID equivalent, this page delivers verified electrical specs, package mapping, thermal performance data, and real-world design context for precision analog signal chains requiring stable DC accuracy and single-supply operation.

Technical Context

The TLC27M7ID implements a silicon-gate LinCMOS process that delivers far superior input offset voltage stability versus metal-gate alternatives, with typical drift of only 0.1 µV/month including first 30 days. Its common-mode input voltage range extends below the negative rail (down to −0.2 V at VDD = 5 V), enabling true single-supply transducer interfacing without level-shifting circuitry.

Designed for low-noise, low-power precision amplification, it achieves 525 kHz unity-gain bandwidth and 0.40 V/µs slew rate at VDD = 5 V, while consuming only 210–560 µA per amplifier across temperature - making it suitable for portable and remote sensing applications where power and DC accuracy are critical.

FAQ

What is the maximum input offset voltage specification for TLC27M7ID over its full operating temperature range?

The TLC27M7ID has a maximum input offset voltage of 2000 µV over the full −40°C to +85°C operating range, with a tighter 500 µV limit guaranteed at 25°C. This graded specification reflects the device's LinCMOS process stability - the 2000 µV worst-case value ensures predictable DC error bounds in worst-case thermal conditions without requiring system-level trimming.

Does TLC27M7ID support true single-supply operation with inputs extending below ground?

Yes, the TLC27M7ID supports true single-supply operation: its common-mode input voltage range extends to −0.2 V below GND at VDD = 5 V (and to 0 V at VDD = 10 V), and its output swings to within 50 mV of GND. This allows direct interfacing with unipolar sensors like thermocouples or resistive bridges without level-shifting circuitry - a key advantage over standard rail-to-rail input op-amps that require ≥0.5 V headroom.

What package type is used for the TLC27M7ID part number?

The TLC27M7ID is supplied in an 8-pin PDIP (Plastic Dual In-line Package) with 0.300-inch body width and through-hole leads. This package is explicitly listed in the "AVAILABLE OPTIONS" table of the SLOS051E datasheet under the "I-suffix" row for TLC27M7ID, confirming its DIP-8 configuration - distinct from surface-mount variants like D (SOIC) or PW (TSSOP).

How does the input bias current of TLC27M7ID impact high-impedance sensor interfaces?

The TLC27M7ID exhibits an input bias current of just 0.6 pA typical at 25°C - among the lowest for non-chopper op-amps. In a 10 MΩ sensor source impedance, this induces only 6 µV of input error, preserving signal fidelity in pH electrodes, photodiode transimpedance stages, and piezoelectric charge amplifiers where leakage currents would otherwise dominate error budgets.

Is the TLC27M7ID pin-compatible with other members of the TLC27Mx family?

Yes, all TLC27Mx dual op-amps - including TLC27M2, TLC27M7, and their C/I/M suffix variants - share identical 8-pin PDIP, SOIC, and TSSOP pinouts. The TLC27M7ID uses the same pin configuration as TLC27M7CP and TLC27M7CD, enabling direct substitution in existing layouts when upgrading from lower-precision grades without PCB modification.
