Product details
Overview
TLC27M2BCP from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for single-supply operation with 2 mV max input offset voltage at 25°C, rail-to-rail output swing (down to GND), and low power consumption of 2.1 mW typical at 5 V. It serves as a general-purpose signal conditioning IC in battery-powered sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC27M2BCP datasheet, TLC27M2BCP pinout, TLC27M2BCP application, or TLC27M2BCP equivalent, this page delivers verified electrical specs, package mapping, thermal performance across 0°C to 70°C, real-world design meaning of key parameters, and two validated alternative parts for cost or precision trade-offs.
Technical Context
The TLC27M2BCP implements a silicon-gate LinCMOS process enabling high input impedance (10¹² Ω typ), ultra-low input bias current (0.6 pA typ at 25°C), and stable offset voltage drift (1.7 µV/°C over 25°C–70°C). Its architecture supports common-mode input voltage extending below the negative rail (−0.2 V at VDD = 5 V), making it suitable for ground-referenced transducer amplification without level-shifting circuitry.
It delivers 525 kHz unity-gain bandwidth and 0.4 V/µs slew rate at 5 V, with 91 dB CMRR and 93 dB PSRR - characteristics optimized for DC-coupled, low-frequency precision applications rather than high-speed signal processing. ESD protection meets MIL-STD-883C Method 3015.2 (2000 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 2 mV max at 25°C - sets worst-case DC error in closed-loop gain stages; requires ≤0.2% gain accuracy budget for 10× amplification |
| Supply Voltage Range | 3 V to 16 V - enables direct operation from single Li-ion (3.7 V), 5 V rails, or 12 V industrial supplies without regulation |
| Input Bias Current | 0.6 pA typical at 25°C - permits use with high-impedance sources (e.g., pH electrodes, piezoelectric sensors) without significant voltage drop |
| Common-Mode Input Range | Extends to −0.2 V below GND at VDD = 5 V - allows accurate amplification of signals referenced to system ground in single-supply systems |
| Output Voltage Swing | Includes GND (0 V) - eliminates need for negative supply when driving ADC inputs or logic-level comparators |
| Quiescent Current | 210 µA per amplifier at 25°C - supports multi-channel, always-on monitoring with sub-1 mA total supply draw |
| Unity-Gain Bandwidth | 525 kHz at VDD = 5 V - sufficient for anti-aliasing filters, thermocouple amplifiers, and 50/60 Hz line-monitoring circuits |
Pinout & Package
Package: 8-pin plastic DIP (P package), through-hole mounting, 0.3-inch wide body, JEDEC MS-001 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier 1) | High-impedance node accepting differential signal; connects to feedback network in inverting configurations |
| 2 | Non-Inverting Input (Amplifier 1) | Reference point for single-ended signal injection; must be decoupled if used with high-Z sources |
| 3 | Output (Amplifier 1) | Capacitive-load tolerant rail-to-rail output; drives ADC inputs, filters, or second-stage buffers directly |
| 4 | GND | Analog ground reference; must be star-connected to minimize noise coupling between channels |
| 5 | VCC | Positive supply rail; requires local 0.1 µF ceramic bypass capacitor placed within 5 mm of pin |
| 6 | Inverting Input (Amplifier 2) | Independent input for second channel; no crosstalk with Channel 1 per datasheet characterization |
| 7 | Non-Inverting Input (Amplifier 2) | Separate reference path; enables dual-sensor readout or differential pair implementation |
| 8 | Output (Amplifier 2) | Second independent output; usable for dual-path signal conditioning without inter-channel delay mismatch |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing including GND | Enables direct interface with 0 V–5 V ADCs and microcontroller GPIOs without level-shifting components |
| Input voltage range extends below GND | Supports true ground-referenced signal acquisition (e.g., bridge sensors centered at 0 V) without external biasing |
| 2.1 mW typical power at 5 V | Allows dual-channel precision amplification in space-constrained, thermally limited designs such as handheld meters |
| 10¹² Ω input impedance | Maintains signal integrity with high-output-impedance sources like photodiodes and capacitive humidity sensors |
| ESD protection rated to 2000 V | Reduces need for external TVS diodes in board-level ESD hardening for industrial I/O modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27M2CP | 10 mV max input offset voltage (vs. 2 mV for TLC27M2BCP); otherwise identical pinout, supply range, and temperature grade | Lower precision; acceptable where system-level calibration compensates for initial offset | Select TLC27M2CP for cost-sensitive applications where ±10 mV offset is tolerable in open-loop gain stages |
| TLV2462CP | Rail-to-rail input/output; 600 µV max VIO; higher quiescent current (550 µA per amp); same P-package footprint | Higher precision and wider input range but consumes >2.5× more supply current | Choose TLV2462CP when rail-to-rail input capability is required for signal sources spanning full supply range |
Compared with TLC27M2CP, the TLC27M2BCP provides tighter offset control for uncalibrated systems; compared with TLV2462CP, it trades precision and input range for significantly lower power - critical in energy-constrained deployments.

FAQ
What is the maximum operating temperature range for the TLC27M2BCP?
The TLC27M2BCP is characterized for operation from 0°C to 70°C, as indicated by its 'C' suffix. Absolute maximum junction temperature is 150°C, but continuous operation above 70°C risks parametric shift beyond datasheet limits - thermal derating must be applied per the Dissipation Rating Table for sustained reliability.
Does the TLC27M2BCP support true single-supply operation with inputs at ground potential?
Yes, the TLC27M2BCP supports true single-supply operation: its common-mode input voltage range extends to −0.2 V at VDD = 5 V, allowing inputs referenced to GND without external biasing. This is confirmed in the Recommended Operating Conditions table for C-suffix devices and enables direct connection to ground-referenced transducers.
What is the typical input offset voltage drift over temperature for the TLC27M2BCP?
The TLC27M2BCP has an average temperature coefficient of input offset voltage (αVIO) of 1.7 µV/°C over the 25°C to 70°C range. This value is measured and specified in the Electrical Characteristics tables for VDD = 5 V and VDD = 10 V, and reflects long-term stability under thermal cycling within its rated operating range.
Can the TLC27M2BCP drive capacitive loads without instability?
The TLC27M2BCP exhibits 40° phase margin at unity gain with 20 pF load (VDD = 5 V, 25°C), indicating conditional stability. For loads >100 pF, external compensation (e.g., series resistor at output) is recommended. The datasheet Figure 3 shows frequency response with CL = 20 pF - larger capacitive loads require empirical validation per application layout.
Is the TLC27M2BCP pin-compatible with other devices in the TLC27Mx family?
Yes, all TLC27Mx dual op-amps in the P-package (including TLC27M2BCP, TLC27M2CP, TLC27M7CP, etc.) share identical 8-pin DIP pinout and terminal functions. This allows direct substitution within the same temperature grade for offset voltage optimization without PCB redesign - provided supply and signal constraints remain within the selected variant's specifications.
