Product details
Overview
TLC27L2CPW from Texas Instruments is a precision dual CMOS operational amplifier in TSSOP-8 package, featuring 10 mV max input offset voltage (25°C), ultra-low 34 µA typical supply current per amplifier at 5 V, and rail-to-rail output swing down to the negative rail. It operates from 3 V to 16 V over 0°C to 70°C and supports single-supply sensor signal conditioning in battery-powered field transmitters.
For engineers reviewing the TLC27L2CPW datasheet, TLC27L2CPW pinout, TLC27L2CPW application, or TLC27L2CPW equivalent, key selection criteria include input offset voltage stability over time (0.1 µV/month drift), common-mode input range extending below ground, and LinCMOS™ process–enabled high input impedance (10¹² Ω) with ESD protection up to 2000 V.
Technical Context
The TLC27L2CPW uses Texas Instruments' silicon-gate LinCMOS™ process to achieve superior offset voltage stability versus metal-gate op amps, with typical 0.1 µV/month drift including first 30 days. Its input stage supports common-mode voltages down to −0.2 V (at VDD = 5 V), enabling true single-supply operation with inputs referenced to ground.
It delivers 85 kHz unity-gain bandwidth and 0.03 V/µs slew rate at 5 V, optimized for low-frequency precision applications such as transmitter front-end amplification and analog sensor buffering where power and DC accuracy are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 10 mV at 25°C - sets worst-case DC error in precision gain stages and sensor bridges |
| Supply Current (typ) | 34 µA per amplifier at 5 V - enables multi-year battery life in remote 4–20 mA loop-powered devices |
| Input Impedance (typ) | 10¹² Ω - minimizes loading on high-Z sources like piezoelectric sensors and pH electrodes |
| Common-Mode Input Range | −0.2 V to 3.5 V at 5 V supply - allows direct interfacing to ground-referenced transducers |
| Output Voltage Swing | Within 50 mV of negative rail - supports full-scale signal capture in single-supply configurations |
| ESD Protection | 2000 V HBM - meets MIL-STD-883C Method 3015.2 for robust handling in industrial assembly |
| Unity-Gain Bandwidth | 85 kHz at 5 V - sufficient for anti-aliasing, low-pass filtering, and slow-scan sensor readout |
Pinout & Package
Packaged in an 8-pin TSSOP (PW), the TLC27L2CPW features a surface-mount footprint measuring 3.0 mm × 4.4 mm with 0.65 mm pitch, suitable for space-constrained PCB layouts in portable instrumentation and distributed I/O modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+ | Noninverting input, channel 1 | High-impedance node for reference or sensor signal connection; accepts voltages down to −0.2 V |
| 1IN− | Inverting input, channel 1 | Feedback path entry point; matched bias current minimizes offset in closed-loop configurations |
| 1OUT | Output, channel 1 | Capable of sourcing/sinking ±30 mA; swings within 50 mV of GND and 0.9 V below VDD |
| GND | Ground / negative supply | Reference for both power and signal; common return for dual-channel operation |
| 2IN+ | Noninverting input, channel 2 | Independent high-Z input for second sensor or signal path; same electrical specs as channel 1 |
| 2IN− | Inverting input, channel 2 | Separate feedback node; no crosstalk with channel 1 due to internal isolation |
| VDD | Positive supply | Accepts 3–16 V; supplies both amplifiers; total IDD ≤ 68 µA at 25°C, 5 V |
| NC | No connect | Pin 7 is unconnected - no internal bond wire; must remain floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power consumption | 34 µA per amplifier at 5 V enables <10 µW/channel operation - ideal for energy-harvesting nodes |
| Latch-up immunity | Designed-in robustness against transient-induced latch-up per JEDEC JESD78 - eliminates need for external current limiting |
| Input offset voltage drift | 0.1 µV/month (including first 30 days) - ensures long-term calibration stability in field-deployed equipment |
| Rail-to-rail output | Swings to within 50 mV of GND and 0.9 V below VDD - maximizes dynamic range in 3.3 V or 5 V systems |
| Single-supply operation | Valid common-mode input range includes negative rail - eliminates level-shifting circuitry for ground-referenced sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L2CDR | Same electrical specs, SOIC-8 package (4.9 × 6.0 mm); higher thermal resistance (5.8 mW/°C derating) | Preferred for through-hole prototyping or legacy board reuse; less suitable for dense PCBs | Select when mechanical compatibility with existing SOIC footprints is required |
| TLV2462IDR | Lower 2 mV VIO max, 100 µA IQ, rail-to-rail I/O, but only rated for 0°C to 70°C and lacks LinCMOS™ long-term drift spec | Better initial accuracy but higher drift; not validated for >10-year field stability | Choose for short-lifecycle consumer designs needing tighter initial offset |
Compared with TLC27L2CDR and TLV2462IDR, the TLC27L2CPW uniquely combines TSSOP-8 miniaturization, 0.1 µV/month offset drift guarantee, and LinCMOS™ process reliability-making it optimal for long-life industrial transmitters where layout density and decades-long calibration stability are jointly critical.

FAQ
What is the maximum operating temperature range for the TLC27L2CPW?
The TLC27L2CPW is characterized for operation from 0°C to 70°C (C-suffix grade). It supports supply voltages from 3 V to 16 V across this range, with guaranteed performance including input offset voltage ≤12 mV and supply current ≤42 µA at 70°C. Operation outside this range is not specified and may result in parametric degradation.
Does the TLC27L2CPW support rail-to-rail input operation?
The TLC27L2CPW does not support rail-to-rail input; its common-mode input voltage range extends to −0.2 V (below GND) and up to 3.5 V at 5 V supply. While this enables true single-supply use with ground-referenced sensors, the noninverting and inverting inputs cannot accept signals at or above VDD. For rail-to-rail input capability, consider the TLV2462IDR instead.
What is the typical input bias current of the TLC27L2CPW at 25°C?
The typical input bias current of the TLC27L2CPW is 0.6 pA at 25°C, with a maximum of 60 pA under specified conditions. This ultra-low value results from the LinCMOS™ process and enables high-accuracy interfacing with high-output-impedance sources such as photodiodes, piezoelectric elements, and pH electrodes without significant current-induced offset errors.
Can the TLC27L2CPW drive capacitive loads directly?
The TLC27L2CPW is stable with capacitive loads up to 20 pF, as verified in the datasheet's test conditions for slew rate and phase margin measurements. Driving larger capacitive loads (e.g., >50 pF) may cause peaking or oscillation; for such cases, an external series resistor (typically 10–100 Ω) should be added between the output and load to maintain stability without degrading bandwidth significantly.
Is the TLC27L2CPW pin-compatible with other TLC27Lx variants?
Yes, the TLC27L2CPW shares identical pinout and package dimensions with all other TLC27Lx variants in PW (TSSOP-8), including TLC27L2ACPW, TLC27L2BCPW, and TLC27L7CPW. All share the same 1IN+, 1IN−, 1OUT, GND, 2IN+, 2IN−, VDD, and NC pin assignments - enabling drop-in replacement for different offset voltage grades without PCB revision.
