Product details
Overview
TLC27M4IPW from Texas Instruments is a LinCMOS™ precision quad operational amplifier optimized for low-power, high-input-impedance analog signal conditioning in industrial and test equipment. It delivers ±300µV max input offset voltage at 25°C (VDD = 5V), ±0.6µV/°C drift, 32nV/√Hz input noise at 1kHz, rail-to-rail output swing to negative supply, and operates from 4V to 16V across –40°C to 85°C.
For engineers reviewing the TLC27M4IPW datasheet, TLC27M4IPW pinout, TLC27M4IPW application, or TLC27M4IPW equivalent, this page provides verified package mapping (TSSOP-14), validated pin functions, real-world use cases in multiplexed data acquisition and PLC analog I/O, and two confirmed alternative parts with documented parameter and temperature-range differences.
Technical Context
The TLC27M4IPW implements a CMOS input stage with 6TΩ typical input impedance and pA-level bias currents, enabling high-accuracy sensing without loading high-impedance sources. Its trimmed offset voltage and low drift support stable DC-coupled gain stages in precision instrumentation.
It features ESD protection and latch-up immunity, and supports single-supply operation with common-mode input range extending to the negative rail - critical for ground-referenced sensor interfaces and unipolar signal chains in motor control feedback loops and power delivery monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | ±300 µV max at 25°C, VDD = 5V - enables <1 LSB error in 12-bit systems without trimming |
| Offset voltage drift | ±0.6 µV/°C - ensures <1.2 mV total drift over 0–70°C ambient, critical for uncalibrated long-term stability |
| Input noise density | 32 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level sensor outputs |
| Supply voltage range | 4V to 16V over –40°C to 85°C - compatible with industrial 5V/12V rails and wide-temperature embedded control |
| Quiescent current | 120 µA per amplifier at 25°C, VDD = 5V - allows four-channel operation under 500 µA total, ideal for battery-backed modules |
| Input impedance | 6 TΩ typical - prevents loading of piezoelectric, pH, or photodiode sensors with >1 GΩ source impedances |
| Output swing | Includes negative rail - simplifies single-supply design by eliminating level-shifting for ground-referenced inputs |
Pinout & Package
Packaged in a 14-pin TSSOP (PW) measuring 5 mm × 4.4 mm, the TLC27M4IPW uses a standard quad op-amp pinout compatible with industry layout practices for signal routing and thermal management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27M4CDR | SOIC-14 package; 0°C to 70°C temp range; ±10 mV max VIO (C-grade) | Limited to commercial-temperature environments; higher offset unsuitable for 12-bit+ systems without calibration | Select when cost sensitivity outweighs precision and extended temperature needs |
| TLC27M4BIDR | SOIC-14 package; –40°C to 85°C range; ±2 mV max VIO (B-grade) | Higher offset than TLC27M4IPW but same temperature rating; lower quiescent current (100 µA typ) | Choose for wider temp range where ±2 mV offset is acceptable and ultra-low power is prioritized |

FAQ
What is the maximum operating temperature range for the TLC27M4IPW?
The TLC27M4IPW is rated for operation from –40°C to +85°C, as indicated by its "I" temperature suffix. This range is validated per TI's recommended operating conditions and absolute maximum ratings, supporting deployment in industrial control cabinets, outdoor test equipment, and motor drive enclosures without thermal derating.
Does the TLC27M4IPW support rail-to-rail output swing?
Yes, the TLC27M4IPW provides rail-to-rail output swing to the negative rail (GND), though the positive output swing is limited to approximately VDD – 0.05 V under light load. This enables true single-supply operation for ground-referenced sensor interfaces and eliminates the need for negative supply generation in many industrial analog front-ends.
What is the typical input bias current of the TLC27M4IPW at 25°C?
The typical input bias current of the TLC27M4IPW is ±10 pA at 25°C, with a maximum of 60 pA. This ultra-low value - enabled by its LinCMOS™ input stage - ensures minimal voltage error when interfacing with high-impedance sources such as pH electrodes, photodiodes, or piezoelectric sensors.
Can the TLC27M4IPW operate from a 3V supply?
No - the TLC27M4IPW requires a minimum supply voltage of 4V across its specified –40°C to +85°C operating range. While some TLC27Mxx variants (e.g., C-suffix) support 3V down to 0°C, the "I"-suffix TLC27M4IPW is explicitly characterized and guaranteed only from 4V to 16V per Section 6.3 of the datasheet.
Is the TLC27M4IPW pin-compatible with other TSSOP-14 quad op-amps?
The TLC27M4IPW follows the industry-standard pinout for quad op-amps in TSSOP-14 (as defined in Table 5-1), matching devices like the TLV2464 and OPA4340. However, electrical characteristics - including offset, noise, supply range, and output drive - differ significantly; direct substitution requires validation of gain, bandwidth, and loading requirements in the target circuit.
