Product details
Overview
TLC27M7IDR from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, delivering 500 µV max input offset voltage at 25°C, 0.1 µV/month offset drift, 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 and supports single-supply transducer interfacing in battery-powered instrumentation.
For engineers reviewing the TLC27M7IDR datasheet, TLC27M7IDR pinout, TLC27M7IDR application, or TLC27M7IDR equivalent, this page provides verified specifications, package mapping (SOIC-8), temperature-rated performance data, and real-world design context for low-power precision analog signal conditioning.
Technical Context
The TLC27M7IDR implements a silicon-gate LinCMOS process enabling ultra-high input impedance (10¹² Ω typ), sub-picoampere input bias current (0.6 pA typ at 25°C), and low 32 nV/√Hz input noise at 1 kHz. Its architecture supports common-mode input voltage extending below the negative rail - critical for single-supply sensor front-ends.
It delivers 525 kHz unity-gain bandwidth and 0.4 V/µs slew rate at VDD = 5 V, with stable phase margin (40° typ) into 20 pF capacitive loads. The device incorporates internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2) and latch-up immunity.
Key Specifications

| Input Offset Voltage | 500 µV max at 25°C - enables high-accuracy DC-coupled amplification without trimming in industrial sensors. |
| Supply Voltage Range | 4 V to 16 V - supports wide-input industrial power rails and extended-life battery operation (e.g., 4×AA). |
| Operating Temperature | −40°C to +85°C - qualified for automotive under-hood and industrial control environments. |
| Input Bias Current | 0.6 pA typ at 25°C - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor interfaces. |
| Output Voltage Swing | Includes negative rail - allows true single-supply operation with ground-referenced inputs and outputs. |
| Common-Mode Input Range | Extends 0.2 V below GND - enables direct connection of unbuffered transducers referenced to system ground. |

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 |
|---|---|---|---|
| TLV2772IDR | Higher speed (2 MHz GBW, 1.2 V/µs SR), but 1.5 mV offset and 2.5× higher quiescent current (550 µA/ch). | Better for AC-coupled active filters; less suitable for DC-stable sensor bridges requiring <1 mV offset. | Select when bandwidth >1 MHz is required and offset tolerance >1 mV is acceptable. |
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C drift, 10 µV max offset), but 17 µA/ch supply current and narrower supply (1.8–5.5 V). | Ideal for ultra-stable DC measurements; incompatible with 12 V industrial rails or battery systems >5.5 V. | Select for sub-µV drift-critical applications where supply is constrained to ≤5.5 V and power budget allows >17 µA/ch. |
Compared with TLV2772IDR and OPA2333AIDR, the TLC27M7IDR uniquely balances ultra-low offset (500 µV), sub-pA bias current, wide 4–16 V supply, and −40°C to +85°C operation - making it optimal for cost-sensitive, long-life, single-supply industrial sensor nodes where moderate bandwidth suffices.

FAQ
What is the maximum input offset voltage specification for TLC27M7IDR across its full operating temperature range?
The TLC27M7IDR has a maximum input offset voltage of 2000 µV over the full −40°C to +85°C range, with a tighter 500 µV limit guaranteed at 25°C. This graded specification reflects typical LinCMOS drift behavior and is validated per TI SLOS051E test conditions using RS = 50 Ω and RL = 100 kΩ loads.
Does TLC27M7IDR support true single-supply operation with inputs referenced to ground?
Yes, the TLC27M7IDR supports true single-supply operation: its common-mode input voltage range extends to −0.2 V (below GND) at VDD = 5 V, and its output swings fully to GND. This allows direct connection of ground-referenced transducers without level-shifting circuitry - a key feature confirmed in the "Common-Mode Input Voltage Range" and "Output Voltage Range" sections of the datasheet.
What package type and reel configuration does TLC27M7IDR use?
TLC27M7IDR is supplied in an SOIC-8 (D) package with tape-and-reel packaging, indicated by the "R" suffix. The D package has standard 150-mil body width and 1.27 mm lead pitch, and is RoHS-compliant. Reel quantity is 2500 units per standard TI reel, compatible with automated SMT placement equipment.
How does the input bias current of TLC27M7IDR compare to bipolar op-amps in sensor applications?
TLC27M7IDR delivers 0.6 pA typical input bias current at 25°C - over six orders of magnitude lower than typical bipolar op-amps (e.g., LM358: ~45 nA). This enables accurate amplification of high-impedance sources like pH electrodes or photodiodes without significant DC error, directly confirmed by TI's electrical characteristics tables under IIB test conditions.
Is TLC27M7IDR pin-compatible with other devices in the TLC27Mx family?
Yes, all TLC27Mx dual op-amps - including TLC27M2x, TLC27M7x, and variants with C/I/M suffixes - share identical SOIC-8 (D), PDIP-8 (P), TSSOP-8 (PW), and ceramic DIP-8 (JG) pinouts. The TLC27M7IDR uses the same 8-pin layout as TLC27M2IDR and TLC27M7CDR, enabling drop-in replacement within the same package variant.
