Product details
Overview
OPA2727AIDRBR from Texas Instruments is a dual-channel, e-trim™ high-precision CMOS operational amplifier in an 8-pin SON (DRB) package. It delivers 150 µV max input offset voltage, 1.5 µV/°C max offset drift, 20 MHz gain-bandwidth, 30 V/µs slew rate, and 4.3 mA/ch quiescent current across ±2 V to ±6 V or +4 V to +12 V supplies. It serves as a low-noise, rail-to-rail output signal conditioner in precision transimpedance, ADC driver, and active filter circuits.
For engineers reviewing the OPA2727AIDRBR datasheet, OPA2727AIDRBR pinout, OPA2727AIDRBR application, or OPA2727AIDRBR equivalent, key selection considerations include its DFN-8 thermal performance, dual-channel channel separation (<1 µV/V), guaranteed –40°C to +125°C operation, and compatibility with single-supply photodiode biasing and fast 16-bit ADC acquisition timing.
Technical Context
The OPA2727AIDRBR implements digital e-trim at package level to correct offset and drift post-molding, avoiding stress-induced parameter shifts. Its CMOS input stage achieves 500 pA max input bias current and 10¹¹ Ω||5 pF differential input impedance, enabling high-impedance sensor interfacing without significant error.
It features a Class AB rail-to-rail output stage delivering 150 mV from rails into 100 kΩ and 250 mV into 1 kΩ loads while maintaining >106 dB open-loop gain. Stability is ensured in unity-gain configurations with capacitive load drive support up to 20 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 20 MHz - enables stable unity-gain buffering of signals up to ~15 MHz with <0.1% settling error. |
| Input Offset Voltage (max) | 150 µV - ensures ≤0.003% full-scale error in 16-bit ±2.5 V ADC driver applications. |
| Offset Drift (max) | 1.5 µV/°C - limits temperature-induced error to <0.15 mV over 100°C ambient range. |
| Slew Rate | 30 V/µs - supports 5 V step response settling in ≤350 ns for 0.1% accuracy. |
| Quiescent Current per Channel | 4.3 mA - allows dual-channel precision amplification within 8.6 mA total supply budget. |
| Supply Voltage Range | +4 V to +12 V (single) or ±2 V to ±6 V - compatible with industrial 5 V/12 V rails and battery-powered 4.5 V systems. |
| Input Bias Current (max) | 500 pA - preserves signal integrity in transimpedance amplifiers with >10 MΩ feedback resistors. |
| Output Swing (from rail) | 150 mV (100 kΩ load) - maximizes dynamic range in single-supply 0–5 V data acquisition systems. |
Pinout & Package
The OPA2727AIDRBR is housed in an 8-pin SON (DRB) package with exposed thermal die pad on underside, requiring connection to V– for thermal and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply rail - accepts +4 V to +12 V or connects to +VS in dual-supply mode. |
| 2 | OUT B | Amplifier B output - rail-to-rail capable, drives 100 kΩ load to within 150 mV of V+ or V−. |
| 3 | IN− B | Inverting input of channel B - high-impedance CMOS node; requires matched layout for common-mode rejection. |
| 4 | IN+ B | Non-inverting input of channel B - referenced to system ground or bias network in single-supply transimpedance designs. |
| 5 | OUT A | Amplifier A output - electrically isolated from OUT B; supports independent signal paths. |
| 6 | IN− A | Inverting input of channel A - shares same input structure and noise specs as IN− B. |
| 7 | IN+ A | Non-inverting input of channel A - used for differential sensing or single-ended buffering with local reference. |
| 8 | V− | Negative supply rail - must connect to PCB thermal pad; serves as return path and thermal sink. |
Key Features

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 architecture; 0.003 µV/°C max drift vs. OPA2727AIDRBR's 1.5 µV/°C; 2 MHz GBW vs. 20 MHz. | Better for ultra-low-drift DC applications (e.g., weigh scales); unsuitable for >1 MHz signal paths or fast settling. | Select OPA2188AIDR only when drift dominates error budget and bandwidth <500 kHz suffices. |
| OPA2182AIDR | Single-supply optimized; 4 µV max offset; 10 MHz GBW; 5.6 mA/ch IQ vs. 4.3 mA/ch. | Lower power-supply rejection (110 dB vs. 150 µV/V) and reduced CMRR limit use in noisy industrial settings. | Prefer OPA2182AIDR for battery-powered portable instruments needing lower offset but tolerating reduced AC performance. |
Compared with OPA2188AIDR and OPA2182AIDR, the OPA2727AIDRBR offers superior bandwidth and settling speed for ADC driving and active filtering, while maintaining competitive DC precision and lower quiescent current than the OPA2182AIDR - making it optimal for mixed-signal industrial and optical systems demanding both speed and stability.

FAQ
What is the maximum operating temperature range for the OPA2727AIDRBR?
The OPA2727AIDRBR is specified for operation from –40°C to +125°C, with absolute maximum junction temperature rated at +150°C. This extended range supports deployment in automotive under-hood modules, industrial motor drives, and outdoor optical transceivers where ambient temperatures exceed +85°C.
Does the OPA2727AIDRBR require external compensation for unity-gain stability?
No, the OPA2727AIDRBR is internally compensated and stable in unity-gain configurations without external components. Its design supports direct use as a voltage follower or buffer in ADC input stages, such as with the ADS8342, without risk of oscillation up to 20 pF capacitive load.
How does the e-trim™ technology in the OPA2727AIDRBR improve long-term reliability?
e-trim™ performs digital offset and drift correction after plastic packaging, eliminating parametric shifts caused by mold stress. This ensures the OPA2727AIDRBR maintains its 150 µV max offset and 1.5 µV/°C max drift specifications over time and temperature - critical for calibration-critical instrumentation where field recalibration is impractical.
Can the OPA2727AIDRBR drive heavy capacitive loads like ADC input capacitance?
Yes, the OPA2727AIDRBR can drive up to 20 pF capacitive loads in unity-gain configuration while maintaining stability and <0.1% overshoot. For heavier loads, a 10 Ω series resistor in the feedback path (as documented in TI's SBOS314H) preserves DC accuracy and suppresses ringing without degrading bandwidth.
What is the purpose of the exposed thermal die pad on the OPA2727AIDRBR package?
The exposed thermal die pad on the bottom of the OPA2727AIDRBR's SON (DRB) package must be soldered to a PCB copper pour connected to V−. It reduces thermal resistance to θJA = 46 °C/W, improves board-level reliability during thermal cycling, and provides mechanical anchoring - essential for sustained operation at 8.6 mA total dissipation in compact layouts.
