Product details
Overview
TLC27L2IDRG4 from Texas Instruments is a precision dual CMOS operational amplifier optimized for low-power, single-supply sensor signal conditioning in industrial and remote applications. It delivers 10 mV max input offset voltage at 25°C, ultra-low 34 µA typical supply current (two amplifiers, VDD = 5 V), and rail-to-rail output swing down to the negative rail - enabling accurate amplification of weak transducer signals in battery-powered field transmitters.
For engineers reviewing the TLC27L2IDRG4 datasheet, TLC27L2IDRG4 pinout, TLC27L2IDRG4 application, or TLC27L2IDRG4 equivalent, key selection criteria include its −40°C to +85°C industrial temperature rating, 10¹² Ω typical input impedance, 0.03 V/µs slew rate, and SOIC-8 package compatibility with legacy analog front-end layouts.
Technical Context
The TLC27L2IDRG4 employs Texas Instruments' LinCMOS™ silicon-gate process, delivering superior offset voltage stability (<0.1 µV/month drift) and latch-up immunity versus metal-gate alternatives. Its dual-channel architecture supports independent signal paths with matched performance across channels.
It operates from 4 V to 16 V over −40°C to +85°C, supports single-supply operation with common-mode input range extending 0.2 V below ground, and features internal ESD protection rated to 2000 V per MIL-STD-883C Method 3015.2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 10 mV at 25°C - defines worst-case DC error in precision gain stages without trimming |
| Supply Current (typ) | 34 µA (two amps, VDD = 5 V) - enables multi-year battery life in wireless sensor nodes |
| Input Impedance (typ) | 10¹² Ω - minimizes loading on high-impedance sources like piezoelectric sensors |
| Common-Mode Input Range | Extends to −0.2 V (VDD = 5 V) - allows direct interfacing with grounded-referenced transducers |
| Output Swing (low) | 1 mV above GND (IOL = 0 mA) - supports full-scale ADC utilization in single-supply systems |
| Slew Rate (typ) | 0.03 V/µs - sufficient for <10 kHz sensor bandwidths while maintaining low power |
| Unity-Gain Bandwidth (typ) | 85 kHz (VDD = 5 V) - enables stable closed-loop gain up to ~100× at DC–1 kHz |
Pinout & Package
Package: SOIC-8 (D), 3.9 mm × 4.9 mm, surface-mount, tape-and-reel compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+ | Noninverting input, channel 1 | High-impedance node for differential sensing or reference biasing |
| 1IN− | Inverting input, channel 1 | Feedback path connection point; sets closed-loop gain and stability |
| 1OUT | Output, channel 1 | Capable of sourcing/sinking ±30 mA; swings within 1 mV of GND |
| GND | Ground / negative supply | Reference for both inputs and outputs; common return for dual-channel layout |
| 2IN+ | Noninverting input, channel 2 | Independent signal path for second sensor or signal processing stage |
| 2IN− | Inverting input, channel 2 | Enables dual-opamp configurations (e.g., instrumentation amp front-end) |
| VDD | Positive supply | Accepts 4–16 V; powers both amplifiers; decoupling required at pin |
| NC | No connect | Pin 8 is unused - no internal connection; must remain unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power consumption | 34 µA total supply current enables >10-year operation on a CR2032 coin cell in intermittent-sampling systems |
| Rail-to-rail output swing | Output reaches within 1 mV of GND and 1.1 V below VDD - maximizes dynamic range for 8–12-bit ADCs |
| Extended common-mode input range | Inputs accept voltages down to −0.2 V (VDD = 5 V), simplifying interface to 4–20 mA loop receivers and grounded thermocouples |
| LinCMOS™ process stability | 0.1 µV/month offset drift ensures calibration validity over 5+ years in field-deployed equipment |
| MIL-STD-883C ESD protection | 2000 V HBM rating reduces failure risk during PCB handling and system integration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV27L2IDR | Lower VIO (5 mV max), same SOIC-8 package, identical pinout, but rated only for 0°C to 70°C | Not suitable for industrial environments requiring −40°C operation | Select when ambient temperature stays within commercial range and tighter offset is prioritized |
| OPA2333AIDR | Zero-drift architecture, 12 µV max VIO, higher supply current (17 µA per amp), 1.8–5.5 V supply range | Requires lower supply voltage; better for ultra-low-VIO designs but incompatible with 12 V field supplies | Select when sub-20 µV offset and near-zero drift are mandatory, and supply is ≤5.5 V |
Compared with TLV27L2IDR and OPA2333AIDR, the TLC27L2IDRG4 uniquely balances industrial temperature range, ultra-low power, and proven LinCMOS™ long-term stability - making it optimal for cost-sensitive, battery-operated field transmitters where 10 mV offset is acceptable.

FAQ
What is the maximum operating temperature range for the TLC27L2IDRG4?
The TLC27L2IDRG4 is rated for continuous operation from −40°C to +85°C, meeting industrial temperature requirements. This is confirmed by its I-suffix designation and specified electrical characteristics across that full range in the official TI datasheet SLOS052E. The device maintains 10 mV max input offset voltage and 34 µA typical supply current within this envelope.
Does the TLC27L2IDRG4 support true rail-to-rail input operation?
The TLC27L2IDRG4 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 (for VDD = 5 V), as specified in Section 5.3 of the datasheet. However, it does provide rail-to-rail output swing, with VOL ≤ 50 mV and VOH ≥ 3.2 V under load.
Can the TLC27L2IDRG4 be used in single-supply 3.3 V systems?
No - the TLC27L2IDRG4 requires a minimum supply voltage of 4 V for guaranteed operation across its full −40°C to +85°C temperature range, per Section 5.3 Recommended Operating Conditions. At 3.3 V, functionality is not assured, and parameters like input offset voltage and output swing degrade outside specification.
What is the input bias current specification for the TLC27L2IDRG4 at 85°C?
At 85°C, the TLC27L2IDRG4 exhibits a maximum input bias current of 2000 pA (2 nA), as documented in Section 5.8 Electrical Characteristics, VDD = 5 V, I Suffix. This value reflects worst-case parametric shift due to temperature and remains well below 10 nA - preserving high-impedance node integrity in sensor interfaces.
Is the TLC27L2IDRG4 pin-compatible with other devices in the TLC27Lx family?
Yes - the TLC27L2IDRG4 uses the standard SOIC-8 (D) package with identical pin configuration and function mapping as all TLC27Lx dual op-amps, including TLC27L2AIDR, TLC27L2BIDR, and TLC27L7IDR. Pin 1 is 1IN+, Pin 2 is 1IN−, Pin 3 is 1OUT, Pin 4 is GND, Pin 5 is 2IN+, Pin 6 is 2IN−, Pin 7 is NC, and Pin 8 is VDD.
