Product details
Overview
OPA990SIDBVR from Texas Instruments is a single-channel, 40-V rail-to-rail input/output operational amplifier with ±300 µV offset voltage, 1.1-MHz gain-bandwidth product, and 120 µA quiescent current per amplifier-designed for high-precision signal conditioning in multiplexed data-acquisition systems.
For engineers reviewing the OPA990SIDBVR datasheet, OPA990SIDBVR pinout, OPA990SIDBVR application, or OPA990SIDBVR equivalent, this device supports high-voltage industrial sensing, ADC driver stages, and comparator-mode operation with MUX-friendly inputs up to supply rails and robust 78 dB EMIRR at 1.8 GHz.
Technical Context
The OPA990SIDBVR implements a high-voltage CMOS input stage enabling rail-to-rail common-mode input range (V– – 0.2 V to V+ + 0.2 V) and differential input tolerance up to supply rails. Its architecture supports open-loop comparator use without phase reversal, enabled by internal protection and stable unity-gain compensation.
It delivers 4.5 V/µs slew rate and 115 dB CMRR at 40 V supply, with ±10 pA bias current and 30 nV/√Hz input voltage noise at 1 kHz-optimized for low-power, high-accuracy amplification across ±1.35 V to ±20 V or 2.7 V to 40 V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 40 V (or ±1.35 V to ±20 V): enables direct interface with 24-V industrial buses and 3.3/5-V logic domains. |
| Input Offset Voltage | ±0.3 mV (max), ±300 µV (typ): ensures sub-LSB error in 16-bit ADC driver applications at room temperature. |
| Gain-Bandwidth Product | 1.1 MHz: supports stable closed-loop gain ≥10 up to ~100 kHz with <0.1% settling in ≤4 µs (10-V step). |
| Slew Rate | 4.5 V/µs: allows full-scale output transitions within microseconds for fast control loop response. |
| Quiescent Current | 120 µA per amplifier: enables battery-powered or energy-constrained designs with minimal thermal load. |
| Input Bias Current | ±10 pA: minimizes voltage error across high-impedance sensor bridges and thermocouple sources. |
| EMIRR Performance | 78 dB at 1.8 GHz: suppresses RF-induced output perturbations in noisy motor drive or power supply environments. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Amplified single-ended output node; rail-to-rail swing (within 2 mV of rails at no load, 45–60 mV at 10-kΩ load). |
| 2 - V– | Negative Supply | Lowest potential supply terminal; connects to system ground or negative rail; thermal pad (if present) must be tied to V–. |
| 3 - IN+ | Noninverting Input | High-impedance CMOS input; accepts signals from V– – 0.2 V to V+ + 0.2 V; MUX-compatible with overvoltage tolerance. |
| 4 - IN– | Inverting Input | High-impedance CMOS input; same common-mode range as IN+; supports precision differential sensing and comparator mode. |
| 5 - V+ | Positive Supply | Highest potential supply terminal; supports up to 40 V; internal ESD clamps limit input pins to V– – 0.5 V / V+ + 0.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems (e.g., 3.3-V microcontroller interfaces) without level-shifting circuitry. |
| MUX-friendly/comparator inputs | Allows direct connection to analog multiplexer outputs; operates reliably in open-loop with no phase reversal up to supply rails. |
| Low offset drift (±0.6 µV/°C) | Reduces temperature-induced gain/offset errors in uncalibrated industrial sensors operating from –40°C to 125°C. |
| High short-circuit current (±80 mA) | Provides robust fault tolerance during transient overloads or accidental shorts-no external current-limiting required. |
| Differential input voltage range to supply rail | Supports true differential signaling across full supply range, critical for high-side current sensing with shunt resistors. |
Applications
| Multiplexed Data-Acquisition System | High-Side Current Sensing |
|---|---|

IC Role / Device Role / Timing Role: OPA990SIDBVR provides low-noise, low-distortion signal conditioning and low-impedance reference buffering. Use Value: 30 nV/√Hz noise and 0.00162% THD+N preserve SNR; rail-to-rail output ensures full-scale reference delivery to ADC REF pin. |
Use Scenario: Zero-crossing detection and threshold comparison in programmable logic controller I/O modules. IC Role / Device Role / Timing Role: OPA990SIDBVR operates open-loop as comparator with hysteresis added externally.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA192IDBVR | Lower offset (±5 µV), higher GBW (10 MHz), higher IQ (1 mA); no shutdown; SOIC/SOT-23-5 pinout identical. | Better for high-speed, ultra-precision applications (e.g., 20-bit DAC buffers); unsuitable where 120 µA IQ is mandatory. | Select OPA192IDBVR only if speed and offset dominate over power; OPA990SIDBVR remains optimal for low-power, high-voltage DAQ. |
| LM358DR | Lower voltage rating (32 V max), higher offset (±2 mV), lower CMRR (90 dB), higher IQ (700 µA); SOIC-8/SOT-23-5 not pin-compatible. | Cost-sensitive, non-critical industrial controls; cannot replace OPA990SIDBVR in 40-V or <1-mV-error systems. | LM358DR requires PCB redesign and performance trade-offs; OPA990SIDBVR offers superior DC accuracy, AC performance, and supply flexibility. |
Compared with OPA192IDBVR, OPA990SIDBVR trades bandwidth and offset for 8.3× lower quiescent current and 40-V operation-making it uniquely suited for always-on, high-voltage, low-power sensing. Versus LM358DR, it delivers 6.7× lower offset, 2.6× better CMRR, and guaranteed 40-V operation without derating.

FAQ
What is the maximum supply voltage rating for OPA990SIDBVR?
The OPA990SIDBVR supports a maximum supply voltage of 40 V (V+ to V–), with absolute maximum ratings allowing up to 42 V for short-duration transients. It operates across ±1.35 V to ±20 V dual supplies or 2.7 V to 40 V single supply-making it suitable for 24-V industrial bus interfaces and wide-input power monitoring circuits. This rating is confirmed in Section 6.1 of the SBOS933I datasheet.
Does OPA990SIDBVR include a shutdown function?
No, the OPA990SIDBVR (SOT-23-5 DBV package) does not include a shutdown pin. Shutdown functionality is only available in the OPA990S variants (e.g., OPA990SIDBVT with 6-pin SOT-23), which add a dedicated SHDN pin (pin 5). The standard OPA990SIDBVR has five pins: OUT, V–, IN+, IN–, and V+. This distinction is clearly documented in Tables 5-1 and 5-2 of the datasheet.
Can OPA990SIDBVR be used as a comparator?
Yes, OPA990SIDBVR can be used open-loop as a comparator due to its MUX-friendly inputs and absence of phase reversal-inputs tolerate differential and common-mode voltages up to the supply rails (V– – 0.2 V to V+ + 0.2 V). However, it lacks built-in hysteresis or push-pull output; external hysteresis and output conditioning are required for clean digital transitions. This capability is explicitly stated in the "MUX-friendly/comparator inputs" feature list.
What is the typical input bias current of OPA990SIDBVR?
The typical input bias current of OPA990SIDBVR is ±10 pA, with a maximum of ±20 pA over temperature (–40°C to 125°C). This ultra-low bias current minimizes voltage errors when interfacing with high-impedance sources such as thermocouples, piezoelectric sensors, or photodiode transimpedance nodes. The value is specified in Section 6.7 (Electrical Characteristics) under "Input Bias Current (IB)".
Is OPA990SIDBVR qualified for automotive applications?
No, OPA990SIDBVR is not AEC-Q200 qualified. It is specified for industrial operation from –40°C to +125°C and carries no automotive qualification. While its temperature range overlaps with some automotive ambient requirements, Texas Instruments positions the OPAx990 family for industrial, test & measurement, and power delivery applications-not automotive safety-critical systems. Automotive-grade alternatives (e.g., OPAxxxA-Q1 series) would be required for qualified deployments.
