Product details
Overview
TLC27M2IP from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for single-supply operation across −40°C to 85°C. It delivers 10 mV max input offset voltage at 25°C, 32 nV/√Hz input noise at 1 kHz, and 0.43 V/µs slew rate at VDD = 5 V - enabling accurate signal conditioning in battery-powered sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC27M2IP datasheet, TLC27M2IP pinout, TLC27M2IP application, or TLC27M2IP equivalent, key selection considerations include its rail-to-rail output swing, common-mode input range extending below ground, low 210 µA supply current per amplifier at 25°C, and guaranteed performance over extended temperature.
Technical Context
The TLC27M2IP employs 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–85°C). Its architecture supports single-supply operation with VICR extending to −0.2 V at VDD = 5 V.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), latch-up immunity, and robust output drive capability (±30 mA). The device exhibits 91 dB CMRR and 93 dB PSRR at 25°C, making it suitable for noisy industrial environments where DC accuracy and AC rejection are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 10 mV max at 25°C - sets baseline DC error in precision gain stages and sensor amplifiers |
| Supply Voltage Range | 4 V to 16 V over −40°C to 85°C - enables direct use with 5 V, 9 V, or 12 V rails without regulation |
| Input Bias Current | 0.6 pA typical at 25°C - minimizes voltage drop across high-impedance source networks (e.g., pH electrodes) |
| Slew Rate | 0.43 V/µs at VDD = 5 V - supports bandwidth-limited signal conditioning up to ~55 kHz full-swing |
| Common-Mode Input Range | −0.2 V to 3.5 V at VDD = 5 V - allows direct interfacing with grounded sensors and transducers |
| Output Voltage Swing | 0–4 V into 100 kΩ load at VDD = 5 V - delivers usable dynamic range near both supply rails |
| Supply Current (dual) | 210 µA typical at 25°C - enables multi-year battery life in remote monitoring nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27M2CP | Same electrical specs but rated for 0°C to 70°C only; lower cost due to commercial temp grade | Not qualified for industrial or automotive ambient conditions beyond 70°C | Select when operating environment stays within 0°C–70°C and cost is primary constraint |
| LM2904DR | Bipolar input; 7 mV max VIO; higher 1.2 mA supply current; no sub-pA bias current | Higher power consumption limits battery life; less suitable for high-impedance sources | Choose for legacy designs needing pin-compatible bipolar op-amp with wider availability |
Compared with TLC27M2CP, the TLC27M2IP offers extended temperature range without sacrificing offset or noise performance; versus LM2904DR, it provides 20× lower supply current and 1000× lower input bias current - critical for precision, low-power, or high-Z applications.

FAQ
What is the maximum input offset voltage specification for TLC27M2IP at 25°C?
The TLC27M2IP has a maximum input offset voltage of 10 mV at 25°C, as specified in the "Electrical Characteristics" table for I-suffix devices at VDD = 5 V. This value applies across the full −40°C to +85°C operating range, with typical drift of 1.7 µV/°C between 25°C and 85°C. The TLC27M2IP datasheet confirms this limit under RS = 50 Ω, VIC = 0, and RL = 100 kΩ test conditions.
Does TLC27M2IP support true single-supply operation with inputs below ground?
Yes, the TLC27M2IP supports true single-supply operation with its common-mode input voltage range extending to −0.2 V at VDD = 5 V (and −0.2 V at VDD = 10 V), verified across the full −40°C to +85°C temperature range. This allows direct interfacing with grounded transducers and sensors without level-shifting circuitry. The TLC27M2IP datasheet explicitly states this capability in the "Recommended Operating Conditions" table.
What is the typical supply current for TLC27M2IP at room temperature and 5 V supply?
The TLC27M2IP draws a typical supply current of 210 µA for both amplifiers combined at 25°C and VDD = 5 V, with a maximum of 560 µA across the full −40°C to +85°C range. This low quiescent current enables multi-year operation in battery-powered systems. The value is measured under no-load conditions with VO = 2.5 V and VIC = 2.5 V, as documented in the TLC27M2IP electrical characteristics tables.
Can TLC27M2IP drive capacitive loads directly, and what is its phase margin?
The TLC27M2IP maintains 38° to 43° phase margin at unity gain with CL = 20 pF and VDD = 5 V or 10 V, as measured in the "Operating Characteristics" section. It is stable driving moderate capacitive loads (≤100 pF) without external compensation, though layout best practices (short traces, local bypassing) are recommended. The TLC27M2IP datasheet confirms stability under these conditions in Figure 3 and associated test notes.
Is TLC27M2IP pin-compatible with other devices in the TLC27Mx family?
Yes, the TLC27M2IP shares identical 8-pin DIP (P) package pinout with all members of the TLC27Mx dual op-amp family, including TLC27M2CP, TLC27M2AP, TLC27M7IP, and TLC27M7CP. Pin functions (OUT A, IN− A, IN+ A, GND, IN+ B, IN− B, OUT B, VCC) are consistent across variants - enabling drop-in replacement based on offset voltage grade and temperature range requirements. This compatibility is confirmed in the TLC27M2IP mechanical drawings and package diagrams.
