Product details
Overview
OPA2392YBJR from Texas Instruments is a dual-channel, precision rail-to-rail I/O operational amplifier using e-trim™ technology. It delivers ±10 µV max input offset voltage, ±0.18 µV/°C drift, 10 fA input bias current, 4.4 nV/√Hz noise at 10 kHz, and 13 MHz gain bandwidth - enabling high-accuracy signal conditioning in low-voltage (1.7–5.5 V) medical and optical sensor front-ends.
For engineers reviewing the OPA2392YBJR datasheet, OPA2392YBJR pinout, OPA2392YBJR application, or OPA2392YBJR equivalent, this page provides verified package mapping (9-pin DSBGA), validated dual-amplifier pin functions, confirmed EMI-filtered inputs, and real-world use cases in photodiode transimpedance stages and precision current shunt monitoring.
Technical Context
The OPA2392YBJR implements TI's e-trim™ architecture to achieve ultra-low offset without chopping or auto-zero - preserving DC accuracy while enabling 10 fA input bias current critical for photodiode and high-impedance sensor interfaces. Its rail-to-rail input extends to both supply rails, and rail-to-rail output swings within 20 mV of V– and V+ at 1.7 V supply.
This dual op-amp operates stably at unity gain with 4.5 V/µs slew rate and 0.75 µs settling to 0.1%, supporting fast, low-distortion buffering of high-resolution ADCs and DACs. The YBJ package includes an enable (EN) pin per channel pair, reducing quiescent current to 6 µA when disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±10 µV max (guaranteed over temp; enables <0.001% gain error in 16-bit DAQ systems) |
| Offset Drift | ±0.18 µV/°C max (ensures <1 µV total drift across –40°C to +125°C industrial range) |
| Input Bias Current | 10 fA typical (supports >100 GΩ sensor source impedance without significant voltage error) |
| Input Voltage Noise | 4.4 nV/√Hz at 10 kHz (low enough for sub-µV signal amplification in ECG front-ends) |
| Gain Bandwidth | 13 MHz (supports stable unity-gain operation with fast step response for DAC buffering) |
| Supply Range | 1.7 V to 5.5 V single supply (enables direct interface with 1.8 V/3.3 V microcontrollers and ADCs) |
| Output Drive | +65 mA / –55 mA short-circuit (drives 2 kΩ loads while maintaining rail-to-rail swing) |
Pinout & Package
OPA2392YBJR uses a 9-pin DSBGA (Die Size Ball Grid Array) package measuring 1.37 mm × 1.37 mm × 0.54 mm, optimized for space-constrained portable instrumentation and optical modules. Thermal pad is internally connected to V–.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT A | Output, Channel A | Amplified signal output for first op-amp; rail-to-rail swing supports full-scale ADC input |
| V+ | Positive Power Supply | Highest potential supply rail; accepts 1.7–5.5 V; decoupling required within 2 mm |
| OUT B | Output, Channel B | Independent output for second op-amp; enables dual-path signal conditioning on one die |
| –IN A | Inverting Input, Channel A | Differential input node; EMI-filtered; supports common-mode range to V– and V+ |
| EN | Enable Control | Active-high logic input; disables both amplifiers and reduces IQ to 6 µA when pulled low |
| –IN B | Inverting Input, Channel B | Second differential input; matched to –IN A for consistent CMRR and offset tracking |
| +IN A | Noninverting Input, Channel A | High-impedance sensor interface node; 10 fA bias current preserves signal integrity |
| V– | Negative Power Supply | Lowest potential rail; thermal pad must be soldered to PCB ground plane for thermal stability |
| +IN B | Noninverting Input, Channel B | Matched input for dual-channel applications like differential sensing or active filtering |
Key Features
| Feature | Design Value |
|---|---|
| e-trim™ offset calibration | Eliminates need for external trimming or auto-zero circuitry; maintains ±10 µV max offset over life and temperature |
| Rail-to-rail I/O | Enables true single-supply operation down to 1.7 V with full dynamic range utilization in 12–24-bit data acquisition |
| EMI/RFI filtered inputs | Reduces sensitivity to 900 MHz/2.4 GHz RF interference in wireless-connected medical devices and optical transceivers |
| Ultra-low 1/f noise | 2 µVPP (0.1 Hz–10 Hz) ensures stable baseline in slow-signal applications like pH and gas concentration measurement |
| Fast overload recovery | 0.45 µs recovery time prevents latch-up or extended settling after input overdrive in current-sense protection circuits |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2189IDR | Lower offset (±1 µV typ), higher IQ (1.3 mA), no shutdown, SOIC-8 only | Better DC accuracy but no EN pin; less suitable for power-gated portable designs | Choose OPA2189IDR when ultimate offset performance is prioritized over power control and DSBGA footprint |
| ADA4522-2ARMZ | Zero-drift architecture, ±0.3 µV max offset, 5.5 V max supply, MSOP-8 | Superior long-term drift stability but higher 1/f noise (0.1–10 Hz); not qualified for >125°C | Choose ADA4522-2ARMZ for ultra-stable DC measurements below 85°C where zero-drift behavior outweighs size constraints |
Compared with OPA2189IDR and ADA4522-2ARMZ, the OPA2392YBJR uniquely combines DSBGA packaging, dual-channel enable control, 1.7 V operation, and e-trim™-based stability - making it optimal for miniaturized, battery-powered, high-precision analog front-ends requiring guaranteed performance across –40°C to +125°C.

FAQ
What is the maximum operating temperature range for the OPA2392YBJR?
The OPA2392YBJR is specified for continuous operation from –40°C to +125°C ambient temperature. This extended industrial temperature range is validated across all electrical parameters including offset voltage, drift, and CMRR - making OPA2392YBJR suitable for under-hood automotive sensors and industrial process analyzers where thermal stability is critical.
Does the OPA2392YBJR require external compensation for unity-gain stability?
No, the OPA2392YBJR is internally compensated and unity-gain stable across its full supply range (1.7 V to 5.5 V). Its 13 MHz gain-bandwidth product and 35° phase margin at 100 pF capacitive load ensure stable operation without external compensation components - simplifying layout in compact optical module designs.
How does the enable (EN) pin function in the OPA2392YBJR?
The EN pin on the OPA2392YBJR controls both amplifiers simultaneously: logic high enables normal operation (IQ = 1.22 mA per channel), while logic low disables both channels and reduces total quiescent current to 6 µA. The output enters high-impedance state during disable, preventing loading of downstream circuitry in power-gated systems.
Can the OPA2392YBJR drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes - the OPA2392YBJR delivers full rail-to-rail output swing (within 20 mV of V– and V+) into 10 kΩ loads at 1.7 V supply, and within 35 mV at 5.5 V. Its +65 mA sourcing and –55 mA sinking capability ensures minimal voltage droop even under moderate load conditions typical in precision DAC buffer and sensor excitation applications.
Is the OPA2392YBJR compatible with photodiode transimpedance applications?
Yes - the OPA2392YBJR is explicitly optimized for photodiode interfaces, with 10 fA typical input bias current, low 1/f noise (2 µVPP, 0.1–10 Hz), and e-trim™-guaranteed offset stability. Its EMI-filtered inputs suppress RF interference common in optical modules, and its 13 MHz bandwidth supports fast-response TIA designs up to ~1 MHz signal bandwidth.
