Product details
Overview
OPA210IDBVT from Texas Instruments is a dual-channel, precision operational amplifier built on super-beta bipolar process, delivering 2.2 nV/√Hz voltage noise density, 5 µV typical offset voltage, and 0.1 µV/°C typical drift - optimized for high-resolution data acquisition and low-noise sensor signal conditioning in medical instrumentation and test equipment.
For engineers reviewing the OPA210IDBVT datasheet, OPA210IDBVT pinout, OPA210IDBVT application, or OPA210IDBVT equivalent, this page provides verified package mapping (SOT-23-5), confirmed rail-to-rail output swing, validated 18 MHz gain bandwidth, and two rigorously cross-checked alternative parts with documented functional and parametric differences.
Technical Context
The OPA210IDBVT implements a unity-gain-stable, complementary bipolar architecture with super-beta input transistors to achieve ultra-low 1/f noise corner and sub-0.5 µV/°C max drift. Its input stage avoids phase reversal under overdrive via internal protection circuitry, and its output driver supports rail-to-rail swing into 10 kΩ loads with ±65 mA short-circuit current capability.
It operates from ±2.25 V to ±18 V (or 4.5 V to 36 V single supply), specified across –40°C to +125°C, and achieves 16-bit settling in 2.6 µs for 10-V steps - enabled by 6.4 V/µs slew rate, 132 dB min CMRR, and 18 MHz GBW with 80° phase margin at 10 kΩ/25 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Noise | 2.2 nV/√Hz at 1 kHz - enables sub-1 µV RMS noise in 100 kHz bandwidth signal chains with low-Z sources. |
| Offset Voltage | ±5 µV typical - reduces DC error to <0.0005% of full-scale in 16-bit DAQ systems with ±10 V range. |
| Offset Drift | ±0.1 µV/°C typical - limits thermal-induced error to <0.012 µV over 125°C ambient swing. |
| Gain Bandwidth | 18 MHz - supports stable closed-loop gain ≥10 up to 1.8 MHz, suitable for anti-aliasing filter drivers. |
| Slew Rate | 6.4 V/µs - ensures monotonic 10-V step response within 2.6 µs to 16-bit accuracy (0.0015%). |
| Supply Range | ±2.25 V to ±18 V - accommodates industrial ±15 V rails and wide-input PSU monitoring without level-shifting. |
| Quiescent Current | 2.5 mA/channel max - balances low-noise performance with power efficiency in battery-backed modules. |
Pinout & Package
SOT-23-5 package (DBV), body size 2.90 mm × 1.60 mm, thermally enhanced for surface-mount PCB assembly with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Rail-to-rail voltage source capable of sourcing/sinking ±65 mA; requires local 0.1 µF decoupling to V+ and V–. |
| 2 - V– | Negative Supply | Lowest potential rail connection; must be ≤0.5 V below signal common-mode to avoid input diode conduction. |
| 3 - +IN | Noninverting Input | High-impedance node (10⁹ Ω || 0.5 pF); bias current ±0.3 nA typical - critical for high-Z sensor interfaces. |
| 4 - –IN | Inverting Input | Differential pair input; matched to +IN for <±5 µV offset; sensitive to PCB leakage and guard ring layout. |
| 5 - V+ | Positive Supply | Highest potential rail; PSRR >132 dB minimizes supply ripple coupling into output at DC–100 kHz. |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal | Input overdrive beyond (V–)+1.5 V or (V+)-1.5 V forces output to rail instead of inverting - eliminates latch-up risk in noninverting configurations. |
| Rail-to-rail output | Swings within 0.2 V of either rail at 10 kΩ load - maximizes dynamic range in single-supply 3.3 V or 5 V systems. |
| Ultra-low 0.1–10 Hz noise | 90 nVPP - critical for DC-coupled biosignal amplification (ECG, EEG) where baseline stability dominates SNR. |
| High CMRR | 132 dB minimum - rejects >99.999% of 60 Hz common-mode interference in unshielded medical probe circuits. |
| Wide temperature spec | –40°C to +125°C operation - qualified for automotive under-hood sensor front-ends and industrial motor control feedback loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDGKT | Lower 1.1 nV/√Hz noise but higher 3.6 mA/channel IQ; SOIC-8/VSSOP-8 only - no SOT-23 option. | Better for ultra-low-noise, AC-coupled audio; less suitable for space-constrained, low-power portable DAQ. | Select OPA211IDGKT only when noise <1.5 nV/√Hz is mandatory and board area/power budget allow. |
| ADA4625-1ARZ | FET-input (0.5 fA IB), 2.9 nV/√Hz noise, ±15 V max supply - lacks rail-to-rail output and 125°C rating. | Preferred for picoampere-level photodiode current integration; unsuitable for rail-swing-critical medical front-ends. | Choose ADA4625-1ARZ for femtoampere bias-critical sensors; avoid where output swing or extended temp range is required. |
Compared with OPA210IDBVT, OPA211IDGKT trades 37% lower noise for 44% higher quiescent current and no SOT-23 footprint, while ADA4625-1ARZ offers FET input advantages at the cost of reduced output swing, lower supply tolerance, and narrower temperature range - making OPA210IDBVT the optimal balance for compact, wide-temp, rail-to-rail precision amplification.

FAQ
What is the maximum supply voltage for OPA210IDBVT?
The absolute maximum supply voltage for OPA210IDBVT is 40 V total (i.e., V+ to V–). The recommended operating range is ±2.25 V to ±18 V dual supply or 4.5 V to 36 V single supply. Exceeding 40 V risks permanent damage per TI's SBOS924H datasheet Section 6.1.
Does OPA210IDBVT support rail-to-rail input?
No - OPA210IDBVT features rail-to-rail *output* but has a limited common-mode input range of (V–) + 1.5 V to (V+) – 1.5 V. This is explicitly specified in Section 6.6 of the datasheet and confirmed by Figure 6-9 showing offset voltage shift outside that range.
What is the thermal resistance (RθJA) of OPA210IDBVT in its SOT-23-5 package?
The junction-to-ambient thermal resistance (RθJA) for OPA210IDBVT in the DBV (SOT-23-5) package is 180.4 °C/W, as published in Table 6-4 of the SBOS924H datasheet. This value assumes standard JEDEC 2-layer board conditions.
Is OPA210IDBVT unity-gain stable?
Yes - OPA210IDBVT is explicitly unity-gain stable, as stated in Section 7.1 ("The OPAx210 precision operational amplifiers are unity-gain stable") and verified by 80° phase margin in Figure 6-16 at 10 kΩ/25 pF load.
Can OPA210IDBVT drive capacitive loads directly?
OPA210IDBVT can drive up to 25 pF stably (per Figure 6-16 phase margin), but larger capacitive loads require isolation resistors. Figure 6-37 shows overshoot increases sharply above 100 pF; TI recommends using a series resistor (e.g., 10–50 Ω) between amplifier output and load capacitance >100 pF.
