Product details
Overview
TLC27L4ACDR from Texas Instruments is a precision quad operational amplifier using LinCMOS™ technology, designed for low-power, single-supply sensor signal conditioning. It delivers 5 mV max input offset voltage (25°C), ultra-low 195 µW quiescent power at 5 V, and rail-to-rail output swing with common-mode input extending below ground. It is widely deployed in battery-powered field transmitters including pressure, temperature, and flow sensing systems.
For engineers reviewing the TLC27L4ACDR datasheet, TLC27L4ACDR pinout, TLC27L4ACDR application, or TLC27L4ACDR equivalent, key selection considerations include its C-suffix 0°C to 70°C operating range, SOIC-14 package, 5 mV VIO grade, and compatibility with low-voltage (3–16 V) single-supply architectures requiring high input impedance (>1012 Ω) and ESD-hardened operation.
Technical Context
The TLC27L4ACDR implements a silicon-gate LinCMOS™ input stage that enables sub-picoampere input bias current (0.6 pA typ.), exceptional DC precision (5 mV VIO max), and stable offset drift (0.1 µV/month). Its architecture supports true single-supply operation with common-mode input range extending 0.2 V below GND and output swing to within 50 mV of GND at 5 V supply.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), latch-up immunity, and operates across 3–16 V supply while maintaining 65–87 dB CMRR and 70–97 dB PSRR - making it suitable for noisy industrial analog front-ends where power efficiency and DC accuracy are jointly critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIO (max) | 5 mV at 25°C - ensures minimal DC error in precision gain stages and sensor offset correction circuits |
| IIB (typ) | 0.6 pA at 25°C - enables high-impedance transducer interfacing without loading thermistors or pH electrodes |
| Supply current | 40–68 µA (4 amplifiers, 5 V) - supports multi-year battery life in remote wireless sensor nodes |
| Common-mode range | –0.2 V to 3.5 V (5 V supply) - allows direct interface to grounded sensors without level-shifting circuitry |
| Output swing | Within 50 mV of GND and 0.9 V of VDD - delivers full dynamic range in 3.3 V or 5 V microcontroller ADC input stages |
| Unity-gain BW | 85 kHz (5 V, 25°C) - sufficient for anti-aliasing and low-frequency active filtering in process control loops |
| CMRR | 65–87 dB - rejects common-mode noise from long-line industrial sensor cables |
Pinout & Package
Package: SOIC-14 (D package), 8.65 mm × 3.91 mm, surface-mount, tape-and-reel compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+, 2IN+, 3IN+, 4IN+ | Noninverting input (ch. 1–4) | High-impedance node for reference or sensor signal routing; accepts voltages down to –0.2 V |
| 1IN–, 2IN–, 3IN–, 4IN– | Inverting input (ch. 1–4) | Supports standard op-amp configurations (inverting amp, integrator, diff-amp) with matched input characteristics |
| 1OUT, 2OUT, 3OUT, 4OUT | Amplifier output (ch. 1–4) | Rail-to-rail capable: drives loads to within 50 mV of GND and 0.9 V of VDD under no-load conditions |
| VDD | Positive power supply | Accepts 3–16 V; supplies all four amplifiers; decoupling required per channel for stability |
| GND | Ground / negative rail | Reference for all inputs/outputs; common return path; must be low-impedance for noise rejection |
Key Features
| Feature | Design Value |
|---|---|
| Input offset voltage drift | 0.1 µV/month - maintains calibration integrity over years in unattended field deployments |
| Single-supply operation | 3–16 V range - eliminates need for dual supplies in portable and industrial sensor modules |
| ESD protection | 2000 V HBM - withstands handling and board-level ESD events without functional degradation |
| High input impedance | 1012 Ω typical - prevents loading of high-Z sources like piezoelectric or capacitive sensors |
| Latch-up immunity | Designed-in - prevents catastrophic failure during overvoltage or reverse-bias transients |

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 |
|---|---|---|---|
| TLV2464IDR | Higher supply current (550 µA/ch), rail-to-rail I/O, 2.5 V min supply, 2.2 MHz GBW | Better for higher-speed, higher-power designs needing full rail-to-rail input/output swing | Select when bandwidth >100 kHz and supply ≥2.5 V are required; not drop-in due to higher IDD and different VIO (2 mV typ) |
| OPA4340UA | CMOS input (0.2 pA IIB), 1 MHz GBW, 1.5 mV VIO, 1.8–36 V supply | Superior precision and speed for medical-grade analog front-ends or precision data acquisition | Choose for tighter DC specs and wider supply range; requires layout review due to different pinout and thermal pad |
Compared with TLV2464IDR and OPA4340UA, the TLC27L4ACDR offers the lowest power consumption and best cost-performance balance for 0–85 kHz sensor signal chains operating from 3–16 V, while trading off bandwidth and input bias current for extreme energy efficiency and legacy design compatibility.

FAQ
What is the maximum operating temperature range for the TLC27L4ACDR?
The TLC27L4ACDR 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 ≤6.5 mV and supply current ≤84 µA at 0°C. Operation outside this range is not specified and may result in parametric degradation.
Does the TLC27L4ACDR support true rail-to-rail input?
The TLC27L4ACDR does not provide full 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), but does not reach VDD. However, it does offer rail-to-rail output swing: output can drive to within 50 mV of GND and within 0.9 V of VDD, enabling effective use in single-supply systems with grounded sensors.
Can the TLC27L4ACDR be used with a 3.3 V supply?
Yes, the TLC27L4ACDR is fully specified for operation at 3.3 V (within its 3–16 V range). At 3.3 V, it maintains 5 mV VIO max, 0.6 pA IIB typ, and common-mode input range of –0.2 V to ~2.1 V. Output swing is reduced to ~25 mV above GND and ~0.7 V below VDD, which remains compatible with 3.3 V ADC references.
Is the TLC27L4ACDR pin-compatible with other TLC27Lx variants?
Yes, the TLC27L4ACDR shares identical SOIC-14 (D) pinout and footprint with TLC27L4CDR, TLC27L4BCDR, and TLC27L9CDR. All variants use the same 14-pin configuration, terminal functions, and recommended PCB layout - allowing direct substitution in existing designs when VIO grade or temperature range requirements change.
What packaging and reel specifications apply to the TLC27L4ACDR?
The TLC27L4ACDR is supplied in SOIC-14 (D package) format on 7-inch tape-and-reel per JEDEC J-STD-020. Standard reel quantity is 2500 units; carrier tape width is 12 mm, pocket pitch is 8 mm, and component cavity depth is 1.75 mm. The device is RoHS-compliant and moisture sensitivity level (MSL) 1 - unlimited floor life at ≤30°C/60% RH.
