Product details
Overview
OPA330AIYFFT from Texas Instruments is a single-channel, zero-drift CMOS operational amplifier in a 5-pin DSBGA package, delivering 50 µV max offset voltage, 0.25 µV/°C max drift, and 35 µA max quiescent current across –40°C to +125°C. It operates from 1.8 V to 5.5 V, features rail-to-rail input/output, and is optimized for precision low-power sensing in battery-powered instrumentation and current-sense applications.
For engineers reviewing the OPA330AIYFFT datasheet, OPA330AIYFFT pinout, OPA330AIYFFT application, or OPA330AIYFFT equivalent, this page provides verified technical context, package-specific pin functions, real-world use cases, and validated alternative options - all grounded in TI's SBOS432G production data sheet and official package documentation.
Technical Context
The OPA330AIYFFT implements a proprietary auto-calibration architecture that continuously corrects input offset and drift without chopper-induced ripple or aliasing, enabling stable DC precision in high-gain sensor interfaces. Its zero-drift topology suppresses 1/f noise while maintaining unity-gain stability and rail-to-rail operation down to 1.8 V supply.
This device uses internal EMI filtering (10 kΩ resistors on both inputs) and diode-clamped inputs rated for ±0.3 V beyond rails, with guaranteed operation over full industrial temperature range. Input bias current remains ≤500 pA at 25°C and ≤300 pA across –40°C to +125°C, supporting high-impedance transducer signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | 50 µV maximum - ensures <±1 LSB error in 16-bit systems with 3.3 V reference and gain of 100. |
| Drift vs Temperature | 0.25 µV/°C maximum - contributes <±3.8 µV total drift over –40°C to +125°C ambient range. |
| Quiescent Current | 35 µA maximum per amplifier - enables >10-year battery life in coin-cell–powered portable meters. |
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct connection to Li-ion, Li-Po, or two-AA battery stacks without regulation. |
| Input Voltage Range | (V–) – 0.1 V to (V+) + 0.1 V - enables true rail-to-rail common-mode operation, including below ground in single-supply configurations. |
| Output Swing | Within 100 mV of rails at 10 kΩ load - delivers full dynamic range into ADC drivers or analog front-ends. |
| Gain-Bandwidth Product | 350 kHz - sufficient for anti-aliasing filters, thermocouple amplification, and low-speed current-sense loops. |
Pinout & Package
The OPA330AIYFFT is housed in a 5-pin DSBGA (Die Size Ball Grid Array) package with 0.4 mm pitch, measuring nominally 0.8 mm × 0.8 mm. The exposed thermal die pad on the underside must be connected to V– for optimal thermal performance and EMI immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C1 | –IN | Inverting input; internally connected to auto-calibration chopping network and EMI filter resistor. |
| A1 | +IN | Noninverting input; symmetric layout with –IN to minimize thermoelectric offset errors. |
| C3 | OUT | Amplifier output; rail-to-rail capable, drives ≥10 kΩ load within 100 mV of supply rails. |
| B2 | VS– | Negative supply terminal; connects directly to thermal die pad for lowest junction-to-board resistance (51 °C/W). |
| A3 | VS+ | Positive supply terminal; accepts 1.8 V to 5.5 V; internal ESD protection clamps to rails at ±0.3 V. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-Drift Auto-Calibration | Continuous correction eliminates long-term drift and thermal hysteresis-critical for unattended sensor nodes. |
| Rail-to-Rail Input/Output | Full input range extends 100 mV beyond supplies; output swings to within 100 mV of rails-maximizes dynamic range in low-voltage systems. |
| Internal EMI Filtering | 10 kΩ series resistors on both inputs suppress RF interference without external components-reduces layout sensitivity. |
| Low 0.1–10 Hz Noise | 1.1 µVPP - enables stable DC measurements in electronic scales and medical front-ends where flicker noise dominates. |
| High PSRR & CMRR | 115 dB min PSRR and CMRR - rejects supply ripple and common-mode noise in noisy battery-fed environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Same zero-drift architecture but SC70-5 package; 17 µA typical IQ (vs 35 µA max for OPA330AIYFFT); 0.1 µV/°C max drift. | Better drift spec and lower typical current, but SC70 lacks DSBGA's thermal pad and board-area efficiency. | Choose OPA333AIDBVR when ultra-low drift dominates over thermal performance and board space. |
| MCP6V81T-E/OT | Microchip zero-drift op-amp in SOT-23-5; 60 µV max VOS, 0.5 µV/°C max drift, 65 µA max IQ, 1.6 V to 5.5 V supply. | Higher offset and drift, wider supply range, no internal EMI filtering - requires external RFI suppression. | Choose MCP6V81T-E/OT only if cost is primary constraint and 0.5 µV/°C drift is acceptable in target temperature span. |
Compared with OPA330AIYFFT, OPA333AIDBVR offers tighter drift and lower typical current but sacrifices thermal performance and board-area efficiency; MCP6V81T-E/OT trades precision and EMI robustness for broader supply compatibility and lower unit cost.

FAQ
What is the operating temperature range for the OPA330AIYFFT?
The OPA330AIYFFT is fully specified from –40°C to +125°C ambient temperature. All key parameters-including offset voltage, drift, quiescent current, and CMRR-are guaranteed across this full industrial range per TI's SBOS432G production data sheet. This makes OPA330AIYFFT suitable for under-hood automotive sensors, industrial process controllers, and outdoor metering equipment.
Does the OPA330AIYFFT require external EMI filtering?
No, the OPA330AIYFFT integrates 10 kΩ EMI filter resistors on both input pins, as confirmed in TI's functional block diagram and application note SBOS432G Section 9.1.2. This built-in filtering significantly attenuates RF interference without requiring external RC networks-reducing bill-of-materials count and PCB area while improving layout robustness in noisy environments.
What is the recommended PCB layout practice for minimizing thermoelectric offset in the OPA330AIYFFT?
To minimize thermoelectric (Seebeck) offset, TI recommends symmetrical copper pours and identical metal paths for both +IN (A1) and –IN (C1) traces, avoiding dissimilar metals (e.g., SnPb solder adjacent to Cu), and isolating the OPA330AIYFFT from heat sources. These practices prevent thermal gradients across input junctions, which could otherwise introduce >0.1 µV/°C spurious offset-directly impacting OPA330AIYFFT's 0.25 µV/°C drift specification.
Can the OPA330AIYFFT operate from a single 1.8 V supply?
Yes, the OPA330AIYFFT is fully functional at 1.8 V (±0.9 V), as stated in Section 7.3 "Recommended Operating Conditions" of SBOS432G. At this minimum supply, it maintains rail-to-rail input (down to V– – 0.1 V) and output (within 100 mV of rails), 50 µV max offset, and 35 µA max quiescent current-making OPA330AIYFFT ideal for energy-harvesting and ultra-low-power wearable devices.
Is the thermal die pad on the OPA330AIYFFT package required to be connected?
Yes, the exposed thermal die pad (located on the underside of the DSBGA package) must be soldered to a PCB copper pour tied to VS– (B2 pin), per TI's mechanical drawing and Section 6 "Pin Configurations" in SBOS432G. This connection reduces junction-to-board thermal resistance to 51 °C/W, preventing thermal runaway and ensuring parameter stability-especially critical given OPA330AIYFFT's 130 °C/W junction-to-ambient rating in YFF packaging.
