Product details
Overview
OPA2364ID from Texas Instruments is a dual, rail-to-rail input/output CMOS operational amplifier optimized for 1.8-V to 5.5-V single-supply operation. It delivers 7-MHz gain-bandwidth, 5-V/µs slew rate, and 90-dB typical CMRR in an 8-pin SOIC package, serving as a precision signal conditioner in battery-powered sensor interfaces and data acquisition front-ends.
For engineers reviewing the OPA2364ID datasheet, OPA2364ID pinout, OPA2364ID application, or OPA2364ID equivalent, key selection criteria include its 500-µV maximum input offset voltage, 750-µA maximum quiescent current per channel, rail-to-rail output swing within 10 mV of supply rails, and –40°C to +125°C industrial temperature rating.
Technical Context
The OPA2364ID employs a complementary CMOS input stage that eliminates crossover distortion, enabling high common-mode rejection without phase reversal-critical for driving SAR ADCs with minimal THD degradation. Its unity-gain stable architecture supports active filter and transimpedance configurations with low noise (17 nV/√Hz at 10 kHz) and wide input common-mode range (–0.1 V to VS + 0.1 V).
Unlike the shutdown-enabled OPA2363 variant, the OPA2364ID lacks enable logic and operates continuously, simplifying biasing in always-on signal chains. It draws ≤750 µA per channel at 5.5 V and maintains 86-dB minimum open-loop gain across –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 7 MHz - supports stable unity-gain amplification up to 7 MHz or closed-loop gains ≥10 at 700 kHz. |
| Slew rate | 5 V/µs - enables clean 20-kHz sinusoidal output at ±2-V amplitude without slew-induced distortion. |
| Input offset voltage | 500 µV max - ensures ≤0.5-mV DC error in 100× gain stages at room temperature. |
| CMRR | 90 dB typical - rejects >30-kV/V common-mode interference, critical for noisy industrial sensor nodes. |
| Supply voltage range | 1.8 V to 5.5 V - powers directly from Li-ion cells (3.0–4.2 V), 3.3-V rails, or regulated 1.8-V logic supplies. |
| Quiescent current | 750 µA/channel max - allows dual-channel operation at <1.5 mA total, extending battery life in portable instrumentation. |
| Output voltage swing | Within 10 mV of rails - delivers full-scale dynamic range into 10-kΩ loads, maximizing ADC utilization. |
Pinout & Package
OPA2364ID is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm, with exposed pad not present and RoHS-compliant lead finish.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage input; rail-to-rail capable. |
| 2 | –IN A | Inverting input for Channel A - connects to feedback network in inverting configurations. |
| 3 | +IN A | Noninverting input for Channel A - accepts sensor signals or reference voltages directly. |
| 4 | V– | Negative supply terminal - tied to ground in single-supply systems; sets lower rail. |
| 5 | –IN B | Inverting input for Channel B - electrically isolated from Channel A; supports dual independent paths. |
| 6 | +IN B | Noninverting input for Channel B - accepts second sensor or differential pair input. |
| 7 | OUT B | Amplifier B output - independent output node; no internal crosstalk with OUT A. |
| 8 | V+ | Positive supply terminal - accepts 1.8–5.5 V; powers both amplifiers simultaneously. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range extends 100 mV beyond both supply rails; output swings to within 10 mV of V+ and V–. |
| No phase reversal | Complementary input stage prevents output inversion during common-mode overdrive - preserves signal integrity in transient-rich environments. |
| Low input bias current | ±1 pA typical at 25°C - minimizes voltage error across high-impedance sources like piezoelectric sensors or pH electrodes. |
| High CMRR | 90 dB typical - maintains accuracy when amplifying small differential signals on noisy power or ground planes. |
| Wide temperature range | Specified from –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and outdoor IoT deployments. |
Applications
| Medical Sensor Interface | Portable Data Logger |
|---|---|
Use Scenario: Amplifying low-level biopotential signals (ECG, EMG) from dry electrodes in wearable patches. IC Role / Device Role / Timing Role: Dual-channel instrumentation front-end: Channel A conditions differential electrode pair; Channel B buffers reference voltage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2365AIDR | 20-MHz GBW, 10-V/µs slew rate, 125-µV max offset, but 1.6-mA/channel IQ and no –40°C to +125°C rating. | Better speed/precision for lab-grade equipment; unsuitable for extended temperature or ultra-low-power use. | Select OPA2365AIDR only if bandwidth >10 MHz and offset <200 µV are mandatory, and power budget allows >3× higher current. |
| MCP6022-I/SN | 10-MHz GBW, 7-V/µs slew rate, 2500-µV max offset, 1000-µA/channel IQ, rated –40°C to +85°C only. | Lower cost for commercial-temp consumer devices; insufficient offset and temp range for industrial sensing. | Choose MCP6022-I/SN for cost-sensitive, non-critical applications where 2.5-mV offset and 85°C max ambient are acceptable. |
Compared with OPA2364ID, OPA2365AIDR trades 3× higher quiescent current for 3× more bandwidth and 4× lower offset, while MCP6022-I/SN offers lower price but sacrifices 5× offset accuracy and fails to meet industrial temperature requirements.

FAQ
What is the maximum operating supply voltage for OPA2364ID?
The OPA2364ID supports a maximum supply voltage of 5.5 V across the V+ to V– terminals. This rating applies across the full –40°C to +125°C temperature range and aligns with its specification in the Recommended Operating Conditions table of the official SBOS259F datasheet. Exceeding 5.5 V risks permanent damage per Absolute Maximum Ratings.
Does OPA2364ID include a shutdown pin?
No, the OPA2364ID does not include a shutdown pin. Unlike the OPA2363 variant, which adds an enable function, the OPA2364ID is a dual op amp with fixed operation-pins 1 through 8 are dedicated to power, inputs, and outputs only. The absence of enable logic simplifies layout and reduces standby current uncertainty in always-on designs.
What is the input bias current specification for OPA2364ID at 25°C?
The input bias current for OPA2364ID is ±1 pA typical and ±10 pA maximum at 25°C, as specified in the Electrical Characteristics table of the SBOS259F datasheet. This ultra-low value enables high-impedance sensor interfacing-such as photodiode or piezoelectric transducers-without significant DC error from leakage paths.
Can OPA2364ID drive a 100-pF capacitive load stably?
Yes, the OPA2364ID is specified to drive up to 100-pF capacitive loads stably in unity-gain configuration, as confirmed by the "FREQUENCY RESPONSE" section of the SBOS259F datasheet. Test conditions for GBW (7 MHz) and slew rate (5 V/µs) explicitly assume CL = 100 pF, and typical characteristics include overshoot vs. load capacitance plots validating stability at this value.
Is OPA2364ID qualified for automotive applications?
The OPA2364ID is not AEC-Q200 qualified and is not marketed by Texas Instruments for automotive use. While it operates from –40°C to +125°C-the same ambient range as many automotive modules-it lacks automotive-specific stress testing, failure analysis reporting, and PPAP documentation required for Tier-1 vehicle integration.
