Product details
Overview
TLC27M7CDR from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, featuring 500 µV max input offset voltage at 25°C, 32 nV/√Hz input noise at 1 kHz, and rail-to-rail output swing down to the negative rail. It operates from 3 V to 16 V supply over 0°C to 70°C and supports single-supply transducer interfacing in battery-powered instrumentation.
For engineers reviewing the TLC27M7CDR datasheet, TLC27M7CDR pinout, TLC27M7CDR application, or TLC27M7CDR equivalent, this page delivers verified package mapping (SOIC-8), confirmed dual-opamp circuit role, temperature-stable offset drift (0.1 µV/month), low-power operation (2.1 mW at 5 V), and real-world design implications for precision analog signal conditioning.
Technical Context
The TLC27M7CDR implements a silicon-gate LinCMOS process that delivers far superior input offset voltage stability versus metal-gate op-amps, with typical input bias current of 0.6 pA at 25°C and high common-mode rejection (91 dB) across its operating range. Its architecture enables true single-supply operation with input voltage range extending below the negative rail.
It integrates internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), latch-up immunity, and robust absolute maximum ratings including ±30 mA output current and 18 V supply tolerance - all while maintaining low 210 µA supply current per amplifier at 25°C and 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 500 µV max at 25°C - enables high-accuracy DC-coupled amplification without external trimming in sensor front-ends. |
| Supply Voltage Range | 3 V to 16 V - supports wide-input industrial and battery-powered systems (e.g., 3.3 V MCU rails up to 12 V industrial supplies). |
| Input Bias Current | 0.6 pA typ at 25°C - preserves signal integrity in high-impedance source applications like piezoelectric sensors or pH electrodes. |
| Output Swing | Includes negative rail - allows full dynamic range utilization in single-supply configurations without level-shifting circuitry. |
| Input Noise Density | 32 nV/√Hz at 1 kHz - suitable for low-level signal amplification in medical ECG or precision weigh-scale circuits. |
| Unity-Gain Bandwidth | 525 kHz at 5 V - sufficient for anti-aliasing filters, active low-pass stages, and moderate-speed sensor signal conditioning. |
| Common-Mode Rejection | 91 dB min - rejects interference from shared ground paths in noisy industrial environments. |
Pinout & Package
Package: SOIC-8 (D package), tape-and-reel compatible (R suffix denotes reel packaging). Pinout matches standard dual op-amp configuration with independent inputs/outputs per channel and shared power/ground rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives load directly; rail-to-rail swing supports full 0–VDD dynamic range. |
| 2 | IN− A | Inverting input for Channel A - high impedance (10¹² Ω) minimizes loading on feedback networks. |
| 3 | IN+ A | Non-inverting input for Channel A - accepts signals down to −0.2 V below GND in single-supply mode. |
| 4 | GND | Analog ground reference - must be low-impedance return path for both amplifiers and bypass capacitors. |
| 5 | IN+ B | Non-inverting input for Channel B - electrically identical to Pin 3; enables dual-channel differential sensing. |
| 6 | IN− B | Inverting input for Channel B - supports independent gain-setting for second signal path. |
| 7 | OUT B | Amplifier B output - fully independent; usable for buffer, filter, or comparator hysteresis functions. |
| 8 | VCC | Positive supply rail - accepts 3–16 V; decoupling capacitor required within 1 cm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Trimmed Input Offset Voltage | 500 µV max ensures <0.05% gain error in 10 V full-scale instrumentation amplifiers without calibration. |
| Low Input Offset Drift | 0.1 µV/month long-term stability reduces recalibration frequency in sealed environmental monitoring systems. |
| Rail-to-Rail Output | Swings to GND enables direct interface with ADCs having 0 V minimum input, eliminating level-shifters. |
| ESD Protection | 2000 V HBM rating allows safe handling in non-ESD-controlled assembly lines without special precautions. |
| Wide Supply Range | 3–16 V operation permits use across 3.3 V microcontrollers, 5 V logic, and 12 V industrial buses without regulators. |

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 |
|---|---|---|---|
| TLV2772IDR | Higher bandwidth (2 MHz), lower noise (17 nV/√Hz), but 2.5 mV max offset and 2.7–5.5 V supply only. | Preferred for higher-speed sensor interfaces where offset can be digitally calibrated; not suitable for 12 V systems. | Select when speed > precision and supply is limited to 3.3 V systems. |
| OPA2333AIDR | Zero-drift architecture, 2 µV max offset, 0.02 µV/°C drift, but 1.8–5.5 V supply and higher cost. | Used where ultra-low drift is critical (e.g., laboratory-grade meters); incompatible with >5.5 V supplies. | Select only if sub-10 µV drift over temperature is mandatory and supply is ≤5.5 V. |
Compared with TLV2772IDR and OPA2333AIDR, the TLC27M7CDR offers the widest supply range (3–16 V) and best balance of precision (500 µV offset), ultra-low bias current (0.6 pA), and industrial temperature capability (0°C to 70°C) at lower cost - making it optimal for uncalibrated, wide-voltage, high-impedance analog front-ends.

FAQ
What is the maximum supply voltage rating for the TLC27M7CDR?
The TLC27M7CDR has an absolute maximum supply voltage of 18 V, with recommended operating range from 3 V to 16 V. This allows safe use in 12 V industrial systems and compatibility with legacy 15 V analog rails, while maintaining specified performance across the full 0°C to 70°C temperature range.
Does the TLC27M7CDR support true single-supply operation with input signals below ground?
Yes, the TLC27M7CDR supports common-mode input voltages down to −0.2 V (at VDD = 5 V), enabling operation with inputs referenced slightly below ground in single-supply configurations. This eliminates the need for level-shifting circuitry when interfacing with bipolar sensors or AC-coupled sources.
What is the typical input bias current of the TLC27M7CDR and why does it matter?
The TLC27M7CDR exhibits a typical input bias current of 0.6 pA at 25°C. This ultra-low value prevents loading errors in high-impedance sensor circuits (e.g., pH electrodes or photodiode transimpedance stages), preserving signal fidelity and minimizing offset drift caused by leakage across PCB contamination or external resistors.
Can the TLC27M7CDR drive heavy capacitive loads directly?
The TLC27M7CDR is not unity-gain stable into heavy capacitive loads (>100 pF) without isolation resistance. For driving ADC input capacitors or long cables, a 100 Ω series resistor between output and load is recommended to maintain phase margin above 39° and prevent oscillation, as verified in the datasheet's stability test conditions.
Is the TLC27M7CDR pin-compatible with other devices in the TLC27Mx family?
Yes, the TLC27M7CDR shares identical SOIC-8 pinout with all C-suffix variants in the TLC27Mx family (e.g., TLC27M2CDR, TLC27M4CDR). This allows drop-in replacement for different offset grades without PCB modification, provided supply and temperature requirements align with the selected variant.
