Product details
Overview
TLC27L2ACPSRG4 from Texas Instruments is a precision dual CMOS operational amplifier optimized for low-power, single-supply sensor signal conditioning. It delivers 5 mV max input offset voltage at 25°C, ultra-low 34 µA typical supply current (VDD = 5 V), and rail-to-rail output swing down to the negative rail - enabling accurate amplification in battery-powered field transmitters and smoke detectors.
For engineers reviewing the TLC27L2ACPSRG4 datasheet, TLC27L2ACPSRG4 pinout, TLC27L2ACPSRG4 application, or TLC27L2ACPSRG4 equivalent, key selection criteria include its 0°C to 70°C operating range, SOIC-8 package, LinCMOS™ input stage with 10¹² Ω impedance, and verified performance in low-voltage analog front-ends requiring long-term offset stability and ESD robustness.
Technical Context
The TLC27L2ACPSRG4 uses Texas Instruments' silicon-gate LinCMOS™ process to achieve high DC precision and low power simultaneously. Its input stage provides ultra-low bias currents (≤60 pA typ) and stable offset voltage drift (0.1 μV/month), while the output stage supports rail-to-rail swing on the negative side and operates reliably from 3 V to 16 V supply.
This C-suffix device is characterized for 0°C to 70°C operation and features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2). Its common-mode input voltage extends 0.2 V below ground, enabling true single-supply interfacing with grounded sensors and transducers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 5 mV at 25°C - enables high-accuracy DC-coupled gain stages without trimming in cost-sensitive industrial sensors |
| Supply Current (typ) | 34 µA at VDD = 5 V - supports multi-year battery life in remote wireless sensor nodes |
| Input Impedance | 10¹² Ω typical - minimizes loading error when buffering high-impedance sources like piezoelectric or pH electrodes |
| Common-Mode Input Range | Extends 0.2 V below GND - allows direct interface with 0–V referenced transducer outputs in single-supply systems |
| Output Swing (low) | ≤50 mV above GND (IOL = 0 mA) - ensures full dynamic range utilization near ground in 3.3 V or 5 V systems |
| Unity-Gain Bandwidth | 85 kHz at VDD = 5 V - sufficient for DC–10 kHz signal conditioning in pressure, temperature, and flow transmitters |
| ESD Rating | 2000 V HBM - meets basic handling robustness requirements for assembly and field deployment |
Pinout & Package
Package: SOIC-8 (PS suffix), 3.9 mm × 4.9 mm body, 1.27 mm pitch, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+ | Noninverting input, channel 1 | High-impedance node for differential or single-ended signal routing; accepts voltages down to −0.2 V |
| 1IN− | Inverting input, channel 1 | Feedback node for closed-loop configurations; matched to 1IN+ for common-mode rejection |
| 1OUT | Output, channel 1 | Capable of sourcing/sinking ±30 mA; swings within 50 mV of GND and 0.9 V of VDD |
| GND | Ground reference | Return path for both channels and supply current; must be low-impedance for noise control |
| 2IN+ | Noninverting input, channel 2 | Independent high-Z input for second signal path; identical specs to 1IN+ |
| 2IN− | Inverting input, channel 2 | Independent feedback node; electrically isolated from channel 1 inputs |
| VDD | Positive supply | Accepts 3 V to 16 V; powers both op-amps; decoupling capacitor required at pin |
| NC | No connect | Pin 8 is unused in PS package - no internal connection; leave unconnected |
Key Features
| Feature | Design Value |

| LinCMOS™ input stage | Delivers 10¹² Ω input impedance and ≤60 pA bias current - critical for high-source-impedance sensor interfaces |
| Single-supply operation | Operates from 3 V to 16 V with input range extending below GND - eliminates need for split supplies in portable systems |
| Ultra-low power | 34 µA typical supply current per dual amplifier - enables always-on sensing in energy-constrained edge devices |
| Latch-up immunity | Designed-in robustness against transient-induced latch-up - improves reliability in noisy industrial environments |

FAQ
What is the maximum operating temperature range for the TLC27L2ACPSRG4?
The TLC27L2ACPSRG4 is a C-suffix device characterized for operation from 0°C to 70°C ambient temperature. It is not rated for extended industrial (−40°C to +85°C) or military (−55°C to +125°C) ranges. Exceeding 70°C may degrade offset voltage, bias current, and phase margin beyond datasheet limits.
Does the TLC27L2ACPSRG4 support true rail-to-rail output?
The TLC27L2ACPSRG4 provides rail-to-rail output swing only on the negative side - it drives down to within 50 mV of GND. On the positive side, VOH is typically 4.1 V at VDD = 5 V, leaving ~0.9 V headroom. It does not achieve full rail-to-rail on both rails.
Can the TLC27L2ACPSRG4 be used with a 3.3 V supply?
Yes, the TLC27L2ACPSRG4 supports VDD as low as 3 V over 0°C to 70°C. At 3.3 V, its common-mode input range extends to −0.2 V, output low is ≤50 mV, and unity-gain bandwidth remains functional (~70 kHz), making it suitable for 3.3 V sensor interfaces.
What is the input bias current specification for the TLC27L2ACPSRG4?
The TLC27L2ACPSRG4 has a typical input bias current of 0.6 pA and a maximum of 60 pA at 25°C (C-suffix, VDD = 5 V). This ultra-low value is enabled by its LinCMOS™ input stage and is critical for minimizing errors in high-impedance sensor circuits.
Is the TLC27L2ACPSRG4 pin-compatible with other TLC27Lx variants?
Yes, all TLC27Lx dual op-amps in SOIC-8 (PS), PDIP-8 (P), or TSSOP-8 (PW) packages share identical pinouts. The TLC27L2ACPSRG4 is pin-compatible with TLC27L2CP, TLC27L2ACDR, and TLC27L7CPSR - differing only in offset grade, temperature range, and packaging.
