Product details
Overview
OPA2727AIDR from Texas Instruments is a dual-channel, e-trim™ high-precision CMOS operational amplifier in SOIC-8 package, delivering 20MHz gain-bandwidth, 30V/µs slew rate, and 150µV max input offset voltage with 1.5µV/°C max drift. It operates from 4V to 12V single or ±2V to ±6V dual supply and is used in precision transimpedance amplifiers for optical networking and high-resolution ADC drivers.
For engineers reviewing the OPA2727AIDR datasheet, OPA2727AIDR pinout, OPA2727AIDR application, or OPA2727AIDR equivalent, key selection criteria include rail-to-rail output swing (150mV from rails), ultra-low bias current (500pA max), low noise (6nV/√Hz at 100kHz), and guaranteed operation from –40°C to +85°C in industrial systems.
Technical Context
The OPA2727AIDR employs e-trim™ technology-digital post-package trimming-to stabilize dc performance against package-induced stress shifts, enabling 15µV typical and 150µV maximum offset voltage across temperature. Its CMOS input stage achieves 500pA max input bias current and 10¹¹ Ω||5pF differential input impedance.
This dual op amp features a class-AB rail-to-rail output stage capable of driving ≥40mA while maintaining >110dB open-loop gain into 100kΩ loads. It is unity-gain stable and optimized for single-supply operation up to 12V, with input common-mode range extending to V– and output swing within 150mV of both rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 20MHz - supports stable unity-gain operation and wideband signal conditioning up to audio and communication frequencies. |
| Input Offset Voltage (max) | 150µV - enables sub-16-bit error budgets in precision sensor interfaces and DAC output buffers without external trimming. |
| Offset Drift (max) | 1.5µV/°C - ensures <1.2mV total offset shift over –40°C to +85°C, critical for uncalibrated industrial temperature sensing. |
| Slew Rate | 30V/µs - allows clean 10Vpp output at 1MHz without slewing distortion in active filter and ADC driver stages. |
| Input Bias Current (max) | 500pA - permits use with high-impedance photodiodes (>100MΩ) and piezoelectric sensors without significant dc error. |
| Supply Voltage Range | 4V to 12V (single) or ±2V to ±6V - compatible with standard 5V and 12V industrial rails and battery-powered instrumentation. |
| Quiescent Current per Channel | 4.3mA - balances precision performance with power efficiency in always-on analog front-ends. |
| Output Swing (vs rail) | 150mV into 100kΩ - maximizes dynamic range in single-supply data acquisition systems with 0–5V or 0–10V full-scale ranges. |
Pinout & Package
OPA2727AIDR is housed in an 8-pin SOIC (D) package with exposed thermal pad connected internally to V–. The pinout is fully specified in TI's SBOS314H datasheet and validated for industrial PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output terminal for Channel A; rail-to-rail capable, drives ≥40mA. |
| 2 | IN– A | Inverting input for Channel A; CMOS input with 500pA max bias current and 10¹¹ Ω impedance. |
| 3 | IN+ A | Non-inverting input for Channel A; supports common-mode range from V– to (V+)–2.5V. |
| 4 | V– | Negative supply rail; internal thermal die pad is electrically tied to this pin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision dual op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2188AIDR | Zero-drift auto-zero architecture; 0.003µV/°C max drift vs. OPA2727AIDR's 1.5µV/°C; 2MHz GBW vs. 20MHz. | Better for µV-level dc stability over wide temperature ranges; unsuitable for >5MHz signal paths. | Select OPA2188AIDR when drift dominates error budget and bandwidth ≤2MHz; choose OPA2727AIDR for wideband precision with moderate drift tolerance. |
| AD8629ARZ | Zero-drift design; 1µV max VOS; 2.5MHz GBW; 1pA max bias current; SOIC-8 package. | Superior dc precision but lower speed and higher cost; not rated for >105°C operation. | Prefer AD8629ARZ in battery-powered portable instruments needing lowest possible offset; retain OPA2727AIDR for industrial 12V systems requiring 20MHz bandwidth and extended temp support. |
Compared with OPA2188AIDR and AD8629ARZ, the OPA2727AIDR offers the highest bandwidth among precision dual op amps in SOIC-8, making it uniquely suited for combined dc accuracy and ac fidelity in ADC drivers and active filters-without zero-drift switching artifacts or bandwidth limitation.

FAQ
What is the maximum operating temperature range for the OPA2727AIDR?
The OPA2727AIDR is specified for operation from –40°C to +85°C, with absolute maximum junction temperature rated at +150°C. This range aligns with industrial-grade requirements and is verified per TI's SBOS314H datasheet under continuous operation with proper PCB thermal design using the SOIC-8 package's exposed thermal pad tied to V–.
Does the OPA2727AIDR support single-supply operation?
Yes, the OPA2727AIDR supports true single-supply operation from 4V to 12V. Its input common-mode range extends to V–, and its rail-to-rail output swings within 150mV of both supply rails into 100kΩ loads-enabling direct interfacing with microcontrollers and ADCs in 0–5V or 0–10V systems without level-shifting circuitry.
Is the OPA2727AIDR pin-compatible with other dual op amps in SOIC-8?
The OPA2727AIDR uses the industry-standard SOIC-8 pinout for dual op amps (pin 1 = OUT A, pin 2 = IN– A, pin 3 = IN+ A, pin 4 = V–, pin 5 = IN+ B, pin 6 = IN– B, pin 7 = OUT B, pin 8 = V+). It is pin-compatible with generic dual op amp footprints, though functional equivalence requires verification of bandwidth, offset, and drive strength for each target application.
What is the typical quiescent current of the OPA2727AIDR per channel?
The typical quiescent current of the OPA2727AIDR is 4.3mA per channel at +25°C and ±5V supply, with a maximum of 6.5mA per channel over temperature. This value is measured under no-load conditions with VOUT = VS/2 and is confirmed in the Electrical Characteristics table of the SBOS314H datasheet.
Can the OPA2727AIDR drive capacitive loads without oscillation?
The OPA2727AIDR is unity-gain stable and can drive moderate capacitive loads (≤20pF) directly. For larger loads, TI recommends adding a 10Ω–20Ω series resistor inside the feedback loop (as shown in Figure 30 of SBOS314H) to maintain phase margin and prevent peaking-especially critical in transimpedance and ADC driver configurations where stray capacitance exceeds 10pF.
