Product details
Overview
TLC27L4BIDG4 from Texas Instruments is a precision quad operational amplifier in SOIC-14 package, featuring 2 mV max input offset voltage at 25°C, ultra-low 195 µW power consumption at 5 V, and rail-to-rail output swing down to the negative rail. It operates from 4 V to 16 V over –40°C to +85°C, enabling use in battery-powered field transmitters and remote sensor interfaces.
For engineers reviewing the TLC27L4BIDG4 datasheet, TLC27L4BIDG4 pinout, TLC27L4BIDG4 application, or TLC27L4BIDG4 equivalent, key selection criteria include input offset voltage stability (0.1 µV/month drift), LinCMOS™ high-input-impedance architecture (10¹² Ω), single-supply operation capability, and ESD protection rated to 2000 V per MIL-STD-883C Method 3015.2.
Technical Context
The TLC27L4BIDG4 implements Texas Instruments' silicon-gate LinCMOS™ process, delivering bipolar-like performance-high gain, low noise (70 nV/√Hz at 1 kHz), and excellent common-mode rejection (65–94 dB)-without bipolar power penalties. Its input stage supports common-mode voltage down to –0.2 V (below GND) and up to 8.5 V at VDD = 10 V.
Designed for precision analog signal conditioning, it provides unity-gain bandwidth of 85 kHz (VDD = 5 V, I-suffix), phase margin of 34°, and slew rate of 0.03 V/µs under standard test conditions. The device incorporates internal ESD-protection circuitry and latch-up immunity, ensuring robustness in industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 2000 µV at 25°C - enables high-accuracy DC-coupled amplification without external trimming in transmitter front-ends |
| Supply Voltage Range | 4 V to 16 V - supports wide-input industrial power rails and extended-life battery operation (e.g., 3× AA or LiSOCl₂) |
| Quiescent Current (per amp) | 17 µA typical at 5 V - allows four-channel operation at ~68 µA total, critical for multi-sensor nodes with <100 µA system budget |
| Input Impedance | 10¹² Ω typical - minimizes loading on high-Z sources like piezoresistive pressure sensors and thermocouples |
| Common-Mode Input Range | –0.2 V to 3.5 V (VDD = 5 V) - permits direct interfacing to ground-referenced transducers without level-shifting circuitry |

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 quiescent current (550 µA/amp), lower VIO (150 µV max), rail-to-rail I/O, wider GBW (6.4 MHz) | Better for higher-speed, higher-accuracy active filters; unsuitable for sub-100 µA battery life targets | Select when speed and precision outweigh power constraints; not drop-in due to different supply current and thermal profile |
| OPA2333PWR | Zero-drift architecture, 2 µV max VIO, 17 µA/amp, but only dual-channel; requires two devices for quad functionality | Superior DC accuracy for medical-grade sensor conditioning; adds PCB area and BOM count vs single quad package | Choose for ultra-low drift (<0.02 µV/°C) in critical diagnostics; not pin-compatible-requires layout revision |
Compared with TLV2464IDR and OPA2333PWR, the TLC27L4BIDG4 uniquely balances micropower operation (68 µA total), moderate precision (2 mV VIO), and true quad integration in SOIC-14-making it optimal for cost- and space-constrained industrial transmitters where 85 kHz bandwidth suffices.

FAQ
What is the maximum operating temperature range for the TLC27L4BIDG4?
The TLC27L4BIDG4 is characterized for operation from –40°C to +85°C (I-suffix grade). This extended industrial temperature range ensures reliable performance in outdoor field transmitters, factory-floor sensors, and automotive under-hood monitoring systems where ambient temperatures exceed commercial limits. The device maintains specified VIO, CMRR, and supply current across this full range.
Does the TLC27L4BIDG4 support true rail-to-rail input operation?
The TLC27L4BIDG4 supports common-mode input voltage down to –0.2 V (below GND) and up to 3.5 V at VDD = 5 V, but does not achieve full rail-to-rail input (i.e., it cannot accept signals equal to VDD). Its input stage is optimized for single-supply use with ground-referenced sensors, not for input voltages spanning the entire supply rail. The TLC27L4BIDG4 output, however, swings within 50 mV of GND and within 1.1 V of VDD.
How does the input offset voltage drift specification impact long-term calibration?
The TLC27L4BIDG4 specifies typical input offset voltage drift of 0.1 µV/month, including the first 30 days. This exceptionally low drift means that over a 5-year deployment, cumulative VIO shift remains under 6 µV-well below its 2000 µV initial spec. As a result, systems using the TLC27L4BIDG4 (e.g., pressure transmitters) can maintain ±0.1% full-scale accuracy without field recalibration, reducing maintenance cost and downtime.
Can the TLC27L4BIDG4 drive capacitive loads directly?
The TLC27L4BIDG4 exhibits a phase margin of 34° at unity gain with 20 pF load, indicating marginal stability with moderate capacitance. Driving >100 pF loads (e.g., long cables or ADC input caps) risks oscillation unless compensated-TI recommends adding a small series resistor (10–100 Ω) between the output and capacitive load. For high-capacitance applications, consider dedicated buffer op-amps with enhanced drive capability.
Is the TLC27L4BIDG4 pin-compatible with other TLC27Lx variants?
Yes-the TLC27L4BIDG4 shares identical SOIC-14 (D) pinout and footprint with TLC27L4, TLC27L4A, and TLC27L9 variants. All TLC27Lx quad op-amps use the same 14-pin configuration (including GND on Pin 11 and VDD on Pin 4), enabling drop-in replacement for different offset voltage grades without PCB modification. However, electrical performance (VIO, drift, bandwidth) differs per grade.
