Product details
Overview
OPA130UAG4 from Texas Instruments is a single-channel, precision FET-input operational amplifier optimized for low-power, high-impedance signal conditioning in battery-powered and portable instrumentation. It delivers 1 MHz gain-bandwidth, 530 µA quiescent current per amplifier, ±1 mV max input offset voltage, and 90 dB min common-mode rejection - enabling accurate amplification of weak sensor signals in data acquisition systems.
For engineers reviewing the OPA130UAG4 datasheet, OPA130UAG4 pinout, OPA130UAG4 application, or OPA130UAG4 equivalent, key selection criteria include its FET-input bias current (≤20 pA), unity-gain stability with ≥10 nF capacitive load drive, and operation across ±2.25 V to ±18 V supplies - critical for precision analog front-ends in medical sensors and industrial transmitters.
Technical Context
The OPA130UAG4 employs an input cascode architecture that maintains ultra-low input bias current (<20 pA) over its full common-mode range (±13 V), eliminating phase reversal even when inputs exceed rails - a known failure mode in legacy FET op amps. Its internal compensation ensures stable unity-gain operation without external components.
It features laser-trimmed input offset voltage (±1 mV max), 120 dB open-loop gain, and rail-to-rail output swing capability (within 1.5 V of rails at ±15 V supply), supporting high-accuracy DC-coupled measurement paths. The device operates from –40°C to +125°C and is qualified for industrial and extended-temperature applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±18 V - supports wide-range battery and dual-rail industrial supplies without level-shifting. |
| Input Offset Voltage | ±1 mV max - enables sub-millivolt DC accuracy in strain gauge and thermocouple interfaces. |
| Quiescent Current | 530 µA per amplifier - allows >1-year battery life in continuous-sensing IoT nodes using two AA cells. |
| Gain-Bandwidth Product | 1 MHz - sufficient for anti-aliasing filtering and sensor signal conditioning up to ~100 kHz. |
| Input Bias Current | 20 pA max at 25°C - preserves signal integrity in photodiode, pH electrode, and piezoelectric sensor circuits. |
| Common-Mode Rejection | 90 dB min - rejects noise from shared ground paths in multi-sensor industrial PLC modules. |
| Capacitive Load Drive | Stable with ≥10 nF - eliminates need for isolation resistors when driving ADC input filters or long cables. |
Pinout & Package
OPA130UAG4 is housed in an 8-pin SOIC (D package), 1.75 mm maximum height, RoHS-compliant with NiPdAu lead finish and JEDEC MS-012 AA compliance. Moisture sensitivity level is Level-3 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Trim (–) | Connects to wiper of 100 kΩ potentiometer for manual nulling of input offset voltage (±5 mV typical trim range). |
| 2 | Inverting Input (–In) | High-impedance FET node; accepts signals up to (V–)+1.2 V and (V+)-2 V without phase reversal. |
| 3 | Non-Inverting Input (+In) | High-impedance FET node; common-mode range extends to within 1.5 V of either rail. |
| 4 | V– | Negative supply connection; must be bypassed with ≥10 nF ceramic capacitor near pin. |
| 5 | Offset Trim (+) | Connects to one end of 100 kΩ potentiometer; used only to null amplifier's intrinsic offset - not system-level offsets. |
| 6 | Output | Capable of sourcing/sinking ±18 mA; swings to within 1.5 V of rails under 2 kΩ load. |
| 7 | V+ | Positive supply connection; must be bypassed with ≥10 nF ceramic capacitor near pin. |
| 8 | NC | No internal connection; left unconnected per TI design - no routing or grounding required. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision FET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA140AIDBVR | Lower input bias current (0.5 pA typ), higher GBW (11 MHz), but 1.2 mA IQ - 2.3× higher quiescent current than OPA130UAG4. | Better for ultra-high-Z sources (e.g., MEMS microphones), less suitable for multi-day battery life requirements. | Select OPA140AIDBVR only if sub-picoamp bias and >1 MHz bandwidth are mandatory; otherwise OPA130UAG4 offers superior power/precision trade-off. |
| TL071CP | Higher IQ (2.5 mA), larger offset (10 mV max), lower CMRR (70 dB), and no guaranteed phase-reversal immunity. | Acceptable for non-critical AC-coupled audio or general-purpose gain stages where DC accuracy is secondary. | Choose TL071CP only for cost-sensitive, non-battery applications where 530 µA IQ and ±1 mV offset are not required. |
Compared with OPA140AIDBVR and TL071CP, OPA130UAG4 uniquely balances ultra-low power (530 µA), precision DC performance (±1 mV offset, 90 dB CMRR), and guaranteed phase-reversal immunity - making it the optimal choice for battery-powered precision instrumentation where both accuracy and longevity are design constraints.

FAQ
What is the maximum capacitive load the OPA130UAG4 can drive while remaining stable?
The OPA130UAG4 is specified for stable operation with capacitive loads up to 10 nF without external compensation. This is confirmed in the Electrical Characteristics table under "Capacitive Load Drive (Stable Operation)" and verified in Typical Characteristics plots showing overshoot vs load capacitance. For loads exceeding 10 nF, a series isolation resistor (typically 10–100 Ω) between the OPA130UAG4 output and the load is recommended to maintain phase margin. The OPA130UAG4's internal compensation ensures unity-gain stability across this range.
Does the OPA130UAG4 require external offset trim, and how is it implemented?
The OPA130UAG4 includes dedicated offset trim pins (1 and 5) for manual nulling of input offset voltage, though laser trimming during production typically renders adjustment unnecessary. To trim, connect a 100 kΩ potentiometer between pins 1 and 5, with its wiper tied to V–. This configuration provides ±5 mV typical trim range. Importantly, the OPA130UAG4 documentation specifies that this adjustment must only null the amplifier's intrinsic offset - not system-level offsets - to avoid degrading temperature drift performance.
What is the operating temperature range for the OPA130UAG4, and is it qualified for automotive use?
The OPA130UAG4 is specified for operation from –40°C to +125°C, as stated in the Absolute Maximum Ratings and Electrical Characteristics tables. While this range overlaps with AEC-Q100 Grade 3 (–40°C to +85°C), the OPA130UAG4 is not officially AEC-Q100 qualified. It is rated for industrial applications and extended-temperature environments, but TI does not list it in their automotive-grade portfolio. For automotive designs, engineers should consult TI's OPAx189 or OPAx192 families, which carry formal AEC-Q100 certification.
Can the OPA130UAG4 be used with single-supply operation, and what are the limitations?
Yes, the OPA130UAG4 supports single-supply operation within its total supply range of 4.5 V to 36 V (i.e., V+ = 4.5 V, V– = 0 V). However, its input common-mode range extends only to (V–)+1.2 V and (V+)-2 V, and output swing is limited to within 1.5 V of each rail. For true rail-to-rail input/output performance, a different amplifier (e.g., OPA333) would be required. In single-supply configurations, proper biasing of the non-inverting input and use of decoupling capacitors on V+ are essential for stable operation.
How does the OPA130UAG4 prevent phase reversal, and why is this important in sensor circuits?
The OPA130UAG4 uses input cascode circuitry that maintains low input bias current and prevents output phase reversal when the input common-mode voltage exceeds the supply rails - a failure mode common in basic JFET-input op amps. This is critical in sensor circuits like voltage followers driving thermocouples or bridge sensors, where transient overvoltage events could otherwise invert feedback polarity and destabilize control loops or corrupt measurements. TI explicitly confirms this immunity in the Applications Information section of the OPA130UAG4 datasheet.
