Product details
Overview
TLC27M2BCDR from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for single-supply operation with rail-to-rail output swing, 2 mV max input offset voltage at 25°C, 0.4 V/µs slew rate (VDD = 5 V), and operation across 0°C to 70°C. It serves as a low-power, high-input-impedance signal conditioning amplifier in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC27M2BCDR datasheet, TLC27M2BCDR pinout, TLC27M2BCDR application, or TLC27M2BCDR equivalent, key selection criteria include its guaranteed 2 mV VIO grade, −0.2 V to 3.5 V common-mode input range (VDD = 5 V), 32 nV/√Hz input noise, 10¹² Ω input impedance, and compatibility with 3–16 V supply rails - critical for precision analog front-ends in industrial and medical devices.
Technical Context
The TLC27M2BCDR implements a silicon-gate LinCMOS process enabling stable offset voltage drift (typically 0.1 µV/month) and latch-up immunity. Its input stage supports common-mode voltage extending below ground, and its output drives to the negative rail - enabling true single-supply functionality without level-shifting circuitry.
It delivers 525 kHz unity-gain bandwidth and 40° phase margin at VDD = 5 V, supporting stable closed-loop operation in active filters and transducer amplifiers. The device exhibits 91 dB CMRR and 93 dB PSRR at 25°C, ensuring robust performance in noisy environments with varying supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 2 mV max at 25°C - enables accurate DC-coupled amplification without external trimming in cost-sensitive systems |
| Supply Voltage Range | 3 V to 16 V - supports direct integration into 3.3 V, 5 V, and 12 V systems without regulators |
| Common-Mode Input Range | −0.2 V to 3.5 V (VDD = 5 V) - accepts signals below ground, simplifying sensor biasing in single-supply designs |
| Output Voltage Swing | Includes negative rail - eliminates need for dual supplies when interfacing with ADCs or microcontrollers referencing GND |
| Input Impedance | 10¹² Ω typical - minimizes loading on high-impedance sources like pH electrodes or piezoelectric sensors |
| Input Noise Density | 32 nV/√Hz at 1 kHz - suitable for low-level signal amplification where thermal noise dominates |
| Quiescent Current | 210–560 µA per amplifier (VDD = 5 V) - enables multi-channel, always-on monitoring in energy-constrained applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV272IDR | Lower VIO (1.25 mV max), higher GBW (2 MHz), but narrower supply range (2.7–16 V) and no guaranteed −0.2 V common-mode capability | Better for high-speed, ultra-low-offset designs; less suitable for sub-ground sensor inputs | Select TLV272IDR only if VIO < 1.5 mV is required and input common-mode never goes below GND |
| LMV358IDR | Higher VIO (3 mV max), rail-to-rail input/output, lower quiescent current (80 µA), but reduced CMRR (70 dB) and no ESD rating above 2 kV | Optimized for ultra-low-power, cost-driven consumer electronics; not recommended for industrial noise immunity | Choose LMV358IDR for battery life >5 years in benign environments; avoid where 91 dB CMRR or 2000 V ESD is mandatory |
Compared with TLV272IDR and LMV358IDR, the TLC27M2BCDR uniquely balances 2 mV VIO guarantee, −0.2 V input capability, 91 dB CMRR, and 2000 V ESD rating - making it the only option among the three qualified for precision, single-supply, noise-immune industrial sensor front-ends.

FAQ
What is the maximum input offset voltage specification for TLC27M2BCDR at 25°C?
The TLC27M2BCDR has a maximum input offset voltage of 2 mV at 25°C, as specified in the "Electrical Characteristics" table for the TLC27M2BC grade under VDD = 5 V conditions. This value is guaranteed across the full 0°C to 70°C operating range, with typical drift of 1.7 µV/°C between 25°C and 70°C. The TLC27M2BCDR maintains this grade consistently due to TI's LinCMOS trimming process.
Does TLC27M2BCDR support true single-supply operation with inputs below ground?
Yes, the TLC27M2BCDR supports common-mode input voltages down to −0.2 V (with VDD = 5 V), explicitly enabling signals referenced below ground - such as thermocouple outputs or grounded-source transducers - without external level-shifting circuitry. This capability is confirmed in the "Recommended Operating Conditions" table and applies across its full 0°C to 70°C temperature range.
What is the supply current consumption of TLC27M2BCDR at 5 V and 25°C?
At VDD = 5 V and 25°C, the TLC27M2BCDR draws 210–560 µA total supply current for both amplifiers, as specified in the "Electrical Characteristics" table. This represents quiescent current only - no load condition, VO = 2.5 V, VIC = 2.5 V. The typical value is 370 µA, making it suitable for always-on, low-duty-cycle sensor monitoring applications.
Is TLC27M2BCDR pin-compatible with standard SOIC-8 dual op-amps?
Yes, the TLC27M2BCDR uses the industry-standard SOIC-8 (D) package with 1.27 mm pitch and identical pinout to generic dual op-amps: Pin 1 = OUT A, Pin 2 = IN− A, Pin 3 = IN+ A, Pin 4 = GND, Pin 5 = IN+ B, Pin 6 = IN− B, Pin 7 = OUT B, Pin 8 = VCC. No PCB layout changes are needed when replacing functionally similar dual op-amps in SOIC-8 footprints.
What is the unity-gain bandwidth of TLC27M2BCDR at 5 V supply?
The unity-gain bandwidth of TLC27M2BCDR is 525 kHz typical at VDD = 5 V and 25°C, as measured under VI = 10 mV, CL = 20 pF conditions. It remains stable across temperature, ranging from 400 kHz at 70°C to 600 kHz at 0°C. This bandwidth supports stable closed-loop gain configurations up to ~50 kHz with adequate phase margin (40° at 25°C).
