Product details
Overview
OPA364IDBVR from Texas Instruments is a single, rail-to-rail input/output CMOS operational amplifier optimized for low-voltage, single-supply operation (1.8 V to 5.5 V). It delivers 7 MHz gain-bandwidth, 5 V/µs slew rate, and 90 dB typical CMRR, with ±10 mV output swing from rails at 25°C - enabling high-fidelity signal conditioning in battery-powered microphone preamplifiers and sensor interfaces.
For engineers reviewing the OPA364IDBVR datasheet, OPA364IDBVR pinout, OPA364IDBVR application, or OPA364IDBVR equivalent, key selection criteria include its 500 µV max input offset voltage, 750 µA max quiescent current per channel, rail-to-rail I/O capability, and SOT-23-5 package compatibility with space-constrained portable systems.
Technical Context
The OPA364IDBVR uses a complementary CMOS input stage that eliminates crossover distortion, ensuring monotonic common-mode response and preserving differential linearity when driving SAR and delta-sigma ADCs. Its unity-gain stable architecture supports direct connection to precision data acquisition front-ends without external compensation.
Operating from 1.8 V to 5.5 V, the device maintains full rail-to-rail input common-mode range (V– – 0.1 V to V+ + 0.1 V) and output swing within 10 mV of both supply rails under 10 kΩ load - critical for maximizing dynamic range in 3.3 V and lower microcontroller-based systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - enables direct integration into Li-ion, coin-cell, and USB-powered systems without level-shifting. |
| Gain-Bandwidth Product | 7 MHz - supports stable amplification of audio-band signals up to 20 kHz with ≥35 dB closed-loop gain margin. |
| Slew Rate | 5 V/µs - ensures <1.5 µs settling to 0.01% for 4-V step inputs, suitable for fast-settling sensor readouts. |
| Input Offset Voltage (max) | 500 µV - minimizes DC error in precision transducer amplification (e.g., bridge sensors, thermopiles). |
| CMRR (typ) | 90 dB - rejects power-supply noise and ground bounce in noisy mixed-signal PCB environments. |
| Quiescent Current (max) | 750 µA per channel - extends battery life in always-on wearable and IoT endpoint devices. |
| Output Swing (from rail) | 10 mV - preserves >99% of available signal headroom in 3.3 V ADC reference designs. |
Pinout & Package
OPA364IDBVR is housed in a 5-pin SOT-23 (DBV) package measuring 2.60 mm × 1.60 mm, optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT | Amplifier output | Delivers rail-to-rail voltage swing; requires local 100-pF bypass capacitor for stability with capacitive loads. |
| 2 - V– | Negative supply | Connects to system ground or lowest potential rail; serves as reference for input common-mode and output swing. |
| 3 - +IN | Noninverting input | High-impedance node (±1 pA bias); accepts signals from resistive sensors or buffered references without loading. |
| 4 - –IN | Inverting input | Used for feedback configuration; matched input capacitance (2 pF diff / 3 pF cm) ensures balanced AC response. |
| 5 - V+ | Positive supply | Accepts 1.8–5.5 V; internal ESD protection clamps to rails; decoupling to V– required within 2 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Supports full-scale signal acquisition across entire supply range - eliminates need for dual supplies in portable instrumentation. |
| No phase reversal | Prevents catastrophic output latch-up during input overdrive - critical for robustness in unconditioned sensor front-ends. |
| 90 dB CMRR (typical) | Maintains accuracy in presence of supply ripple or shared ground paths - reduces post-processing calibration effort. |
| 17 nV/√Hz input voltage noise | Enables clean amplification of low-level microphone and piezoelectric signals without degrading SNR below 100 dB. |
| Unity-gain stable | Operates reliably with no external compensation in gain = 1 configurations - simplifies layout and BOM for buffer applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 10 µV max offset; 350 kHz GBW; 17 µA IQ | Better DC accuracy for ultra-low-frequency sensor signals; lower bandwidth limits audio use. | Select for sub-1 µV/°C drift-critical applications like precision weight scales; avoid where >1 MHz signal fidelity is needed. |
| MCP6001T-E/OT | 1 MHz GBW; 0.6 V/µs slew rate; 100 µV max offset; 100 nA IB | Lower power (100 µA IQ) but reduced speed and CMRR (70 dB); not rail-to-rail input. | Choose for cost-sensitive, low-speed battery monitoring; reject for microphone preamp or ADC driver roles requiring full rail compliance. |
Compared with OPA364IDBVR, OPA333AIDBVR trades bandwidth for near-zero drift, while MCP6001T-E/OT sacrifices speed and CMRR for ultra-low quiescent current - making OPA364IDBVR the optimal balance of speed, precision, and single-supply flexibility in mid-bandwidth analog front-ends.

FAQ
What is the maximum supply voltage for OPA364IDBVR?
The OPA364IDBVR supports a maximum supply voltage of 5.5 V across the V+ to V– terminals. Operation beyond this rating risks permanent damage. The device is fully specified from 1.8 V to 5.5 V, with performance parameters including gain-bandwidth and output swing validated across this full range - making OPA364IDBVR suitable for both 3.3 V microcontroller systems and 5 V legacy interfaces.
Does OPA364IDBVR include a shutdown pin?
No, OPA364IDBVR does not include a shutdown pin. That functionality is exclusive to the OPA363 family (e.g., OPA363IDBVR), which uses a 6-pin SOT-23 package with an Enable terminal. The OPA364IDBVR is a 5-pin variant without enable logic; its quiescent current remains at 750 µA max per channel in all operating conditions - confirmed in the Electrical Characteristics table of the SBOS259F datasheet.
What is the input bias current specification for OPA364IDBVR?
The OPA364IDBVR features ultra-low input bias current of ±1 pA typical and ±10 pA maximum at 25°C, due to its CMOS input stage. This value increases slightly over temperature but remains below 100 pA across the full –40°C to +125°C range - enabling high-impedance sensor interfacing (e.g., pH electrodes, photodiode transimpedance) without significant DC error or signal loading.
Can OPA364IDBVR drive capacitive loads?
Yes, OPA364IDBVR can drive capacitive loads up to 100 pF while maintaining stability in unity-gain configuration, as verified in the Typical Characteristics section (Figure 13 and Figure 19). For loads exceeding 100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended. The device's unity-gain stability and 7 MHz GBW make OPA364IDBVR robust for driving ADC input capacitance and PCB trace capacitance in compact layouts.
Is OPA364IDBVR RoHS compliant and lead-free?
Yes, OPA364IDBVR is RoHS compliant and lead-free. Per Texas Instruments' official packaging information, the DBV (SOT-23-5) package uses lead-free matte tin plating and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements. The device carries the "Green" designation in TI's orderable addendum and conforms to EU RoHS Directive 2011/65/EU - confirmed in TI's Quality & Environmental Information portal for OPA364IDBVR.
