Product details
Overview
TLC27M2ACDR from Texas Instruments is a dual precision LinCMOS operational amplifier with 5 mV maximum input offset voltage at 25°C, rail-to-rail output swing down to the negative rail, and operation from 3 V to 16 V supply across 0°C to 70°C. It delivers 0.40 V/µs slew rate, 32 nV/√Hz input noise at 1 kHz, and 525 kHz unity-gain bandwidth at VDD = 5 V - enabling low-power sensor signal conditioning in battery-powered industrial monitoring systems.
For engineers reviewing the TLC27M2ACDR datasheet, TLC27M2ACDR pinout, TLC27M2ACDR application, or TLC27M2ACDR equivalent, key selection criteria include its 5 mV initial offset grade (mid-tier precision), single-supply compatibility with extended common-mode range below ground, low 2.1 mW power consumption at 5 V, and D-package SOIC-8 footprint for space-constrained analog front-ends.
Technical Context
The TLC27M2ACDR uses silicon-gate LinCMOS process technology to achieve 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 internal ESD protection withstands 2000 V per MIL-STD-883C Method 3015.2.
Designed for single-supply operation, it supports common-mode input voltage down to −0.2 V (at VDD = 5 V) and output swing to within 50 mV of GND. The device exhibits 91 dB CMRR and 93 dB PSRR at 25°C, making it suitable for DC-coupled transducer interfaces where supply rejection and noise immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 5 mV max at 25°C - defines worst-case DC error in precision gain stages without trimming |
| Supply Voltage Range | 3 V to 16 V - enables direct operation from single Li-ion, 5 V logic rails, or unregulated 12 V supplies |
| Slew Rate | 0.40 V/µs typ at VDD = 5 V - supports ≤50 kHz full-swing signals in unity-gain buffer applications |
| Input Noise Density | 32 nV/√Hz at 1 kHz - limits resolution in low-frequency sensor amplification (e.g., strain gauges) |
| Unity-Gain Bandwidth | 525 kHz typ at VDD = 5 V - sets upper frequency limit for stable closed-loop gain ≥1 configurations |
| Common-Mode Input Range | −0.2 V to 3.5 V at VDD = 5 V - allows direct interfacing with grounded sensors and bipolar signal sources |
| Output Voltage Swing | Within 50 mV of GND and within 100 mV of VDD - ensures full dynamic range utilization in single-supply data acquisition |
Pinout & Package
Package: SOIC-8 (D package), tape-and-reel format (R suffix), 1.75 mm height, industry-standard 150 mil width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Drives external load; rail-to-rail swing capability enables full-scale ADC input drive |
| 2 (IN− A) | Inverting input A | High-impedance node (10¹² Ω); accepts feedback networks for precise gain control |
| 3 (IN+ A) | Non-inverting input A | Accepts low-current sensor signals (e.g., thermocouple, bridge outputs) without loading |
| 4 (GND) | Analog ground reference | Return path for both amplifiers; must be low-impedance to minimize offset drift |
| 5 (IN+ B) | Non-inverting input B | Independent input for second channel; supports dual-sensor or differential pair configurations |
| 6 (IN− B) | Inverting input B | Supports independent feedback; usable for instrumentation amp front-end or active filter sections |
| 7 (OUT B) | Amplifier B output | Second independent output; shares same supply and thermal environment as Channel A |
| 8 (VCC) | Positive supply rail | Accepts 3–16 V; internal regulation not required; decoupling capacitor essential for stability |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives loads to within 50 mV of GND and 100 mV of VCC - eliminates need for level-shifting in 3.3 V/5 V systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV272IDR | Lower 2 mV VIO max, 1.25 V min supply, 1.25 MHz GBW - higher precision but narrower supply range | Better for ultra-low-voltage (1.8–3.3 V) portable designs; less suitable for 12 V industrial rails | Select TLV272IDR when sub-2 mV offset and 1.25 V operation are mandatory; retain TLC27M2ACDR for 3–16 V flexibility and proven ruggedness |
| LMV358IDR | 7 mV VIO max, rail-to-rail I/O, 1 MHz GBW, 0.6 V min supply - lower cost, higher offset, wider voltage range | Preferred for cost-sensitive consumer electronics where 7 mV offset is acceptable | Choose LMV358IDR for budget-constrained designs with relaxed DC accuracy; TLC27M2ACDR remains optimal for mid-precision industrial analog front-ends |
Compared with TLV272IDR and LMV358IDR, the TLC27M2ACDR occupies a unique middle ground: tighter offset than LMV358IDR yet broader supply range than TLV272IDR, making it ideal for mixed-voltage industrial systems requiring stable performance from 3 V to 16 V without sacrificing precision.

FAQ
What is the maximum input offset voltage specification for the TLC27M2ACDR at 25°C?
The TLC27M2ACDR has a maximum input offset voltage of 5 mV at 25°C, as specified in the electrical characteristics table under VDD = 5 V test conditions. This value applies across the full operating temperature range (0°C to 70°C) for the C-suffix grade, and represents the worst-case initial DC error before trimming or system calibration. The TLC27M2ACDR achieves this mid-precision grade while maintaining low power and wide supply voltage capability.
Does the TLC27M2ACDR support true single-supply operation with inputs extending below ground?
Yes, the TLC27M2ACDR supports true single-supply operation with its common-mode input voltage range extending to −0.2 V (at VDD = 5 V) - i.e., 200 mV below the negative rail (GND). This capability is explicitly confirmed in the recommended operating conditions table and enables direct interfacing with grounded sensors such as thermocouples or resistive bridges without requiring level-shifting circuitry. The TLC27M2ACDR maintains this feature across its full 0°C to 70°C temperature range.
What is the typical supply current consumption of the TLC27M2ACDR at 5 V?
The TLC27M2ACDR draws a typical supply current of 210 µA per amplifier, or 420 µA total for both channels, at VDD = 5 V and 25°C with no load. This corresponds to approximately 2.1 mW total power dissipation. The datasheet confirms this value under "IDD Supply current (two amplifiers)" in the electrical characteristics section for the TLC27M2AC grade, making the TLC27M2ACDR well-suited for battery-powered applications where low quiescent current is critical.
Is the TLC27M2ACDR pin-compatible with other devices in the TLC27Mx family?
Yes, the TLC27M2ACDR is pin-compatible with all other dual variants in the TLC27Mx family housed in the SOIC-8 (D) package, including TLC27M2CDR, TLC27M2BCDR, TLC27M7CDR, and their I-suffix and M-suffix counterparts. Pin assignments - including dual amplifier inputs/outputs, VCC, and GND - are identical across the family. This allows direct substitution based on required offset voltage grade (2 mV, 5 mV, or 500 µV) or temperature range without PCB layout changes, provided the selected variant shares the same D-package footprint.
What packaging and reel options are available for the TLC27M2ACDR?
The TLC27M2ACDR is supplied in an 8-pin SOIC (D) package in tape-and-reel format, as indicated by the "R" suffix in the part number. Per the datasheet's ordering information, the D package is explicitly listed as available taped and reeled, and the R suffix denotes this configuration. Standard reel quantities are 2500 units per reel, compatible with automated SMT placement equipment. No other package variants (e.g., TSSOP, PDIP) carry the "R" suffix for this specific grade - only the SOIC-8 D package is offered in reel form for the TLC27M2ACDR.
