Product details
Overview
OPA2364AIDGKTG4 from Texas Instruments is a dual, rail-to-rail input/output, 7-MHz bandwidth CMOS operational amplifier optimized for single-supply operation from 1.8 V to 5.5 V. It delivers 90-dB typical CMRR, 5 V/µs slew rate, and ≤500 µV maximum input offset voltage - enabling precision signal conditioning in battery-powered sensor interfaces and audio preamplifiers.
For engineers reviewing the OPA2364AIDGKTG4 datasheet, OPA2364AIDGKTG4 pinout, OPA2364AIDGKTG4 application, or OPA2364AIDGKTG4 equivalent, key selection considerations include its dual-channel SOIC-8 package, 750 µA/channel quiescent current at 1.8 V, rail-to-rail I/O swing within 10 mV of supply rails, and –40°C to +125°C industrial temperature rating.
Technical Context
The OPA2364AIDGKTG4 implements a complementary CMOS input stage that eliminates crossover distortion, ensuring high common-mode rejection (90 dB typ.) across the full input range - from (V–) – 0.1 V to (V+) + 0.1 V - without degradation of THD or differential linearity when driving ADCs. Its unity-gain stable architecture supports low-noise active filtering and microphone preamplification with minimal phase shift.
Unlike the shutdown-capable OPA2363 family, the OPA2364AIDGKTG4 omits enable pins and operates continuously, simplifying biasing in always-on signal chains. It draws only 750 µA per channel at 1.8 V and maintains 100 dB open-loop gain (AOL) at 25°C with 10 kΩ load, supporting high-precision DC-coupled amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 7 MHz - enables accurate amplification of audio-band and fast-sensor signals up to ~1 MHz closed-loop (G = 1). |
| Slew Rate | 5 V/µs - supports clean 20-kHz sinusoidal output at ≥2-Vpp without slew-induced distortion. |
| CMRR | 90 dB (typ.) - rejects power-supply noise and common-mode interference in single-supply systems with shared ground references. |
| Input Offset Voltage | ≤500 µV (max.) - ensures ≤0.5-mV DC error in 1-V full-scale sensor amplification, critical for 12-bit+ resolution. |
| Quiescent Current | 750 µA/channel (max. at 1.8 V) - allows dual-channel operation on coin-cell or energy-harvested supplies for >1-year battery life. |
| Output Swing | Within 10 mV of rails (RL = 10 kΩ) - maximizes dynamic range in 1.8-V or 3.3-V systems without level-shifting circuitry. |
| Supply Range | 1.8 V to 5.5 V - compatible with Li-ion, Li-Po, and regulated 3.3-V/5-V rails without external LDOs. |
Pinout & Package
OPA2364AIDGKTG4 is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm, with standard JEDEC MS-012AC footprint and 1.27-mm lead pitch. Thermal resistance RθJA is 125.3°C/W, supporting operation up to +125°C ambient with moderate PCB copper area.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 10 kΩ while maintaining rail-to-rail swing and <0.01% settling in 1.5 µs. |
| 2 | –IN A | Inverting input for Channel A - accepts signals from (V–) – 0.1 V to (V+) + 0.1 V; high-impedance (≥1012 Ω) minimizes loading on passive filters. |
| 3 | +IN A | Noninverting input for Channel A - identical common-mode range as –IN A; used for unity-gain buffers and high-Z sensor interfaces. |
| 4 | V– | Negative supply terminal - referenced to system ground in single-supply configurations; must be decoupled with ≥0.1 µF ceramic capacitor. |
| 5 | –IN B | Inverting input for Channel B - electrically isolated from Channel A; supports dual-path signal processing without crosstalk (≥130 dB at DC). |
| 6 | +IN B | Noninverting input for Channel B - matches Channel A performance; enables differential-input instrumentation amplifier topologies using external resistors. |
| 7 | OUT B | Amplifier B output - independently buffered; usable for feedback paths, reference buffering, or second-stage gain without shared node impedance. |
| 8 | V+ | Positive supply terminal - accepts 1.8–5.5 V; PSRR of 80–330 µV/V ensures stable operation under noisy digital supply conditions. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input range extends 100 mV beyond both rails; output swings to within 10 mV of V+ and V– - preserves full ADC input range in 1.8-V systems. |
| No phase reversal | CMOS input stage prevents output inversion during overdrive or input common-mode excursion - avoids latch-up in sensor fault conditions. |
| Low input bias current | ±1 pA (typ. at 25°C) - enables use with high-impedance sources (e.g., piezoelectric sensors, pH electrodes) without significant DC error. |
| Unity-gain stable | Stable with capacitive loads ≤100 pF and no external compensation - simplifies layout for EMI-filtered sensor inputs or long traces. |
| High CMRR at AC | ≥74 dB maintained up to 10 kHz - suppresses switching noise from DC-DC converters in mixed-signal embedded systems. |
Applications
| Audio Signal Chain | Industrial Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2365AIDGKT | Higher bandwidth (50 MHz), lower noise (4.5 nV/√Hz), but higher IQ (1.6 mA/channel); no guaranteed 125°C operation. | Better for wideband active filters or high-speed data acquisition; unsuitable for extended-temperature industrial use. | Select OPA2365AIDGKT only if bandwidth >10 MHz is required and thermal margin permits. |
| MCP6022-I/SN | Lower bandwidth (10 MHz), higher offset (2.5 mV max), wider supply range (2.7–6.0 V); specified only to +85°C. | Cost-optimized for consumer-grade 3.3-V systems; lacks rail-to-rail input and industrial temp support. | Choose MCP6022-I/SN for non-critical, cost-sensitive designs where 125°C operation and <500 µV offset are not required. |
Compared with OPA2364AIDGKTG4, OPA2365AIDGKT trades power efficiency and temperature robustness for speed and noise performance, while MCP6022-I/SN sacrifices precision and thermal range for lower unit cost - making OPA2364AIDGKTG4 the optimal balance for industrial and automotive sensor signal chains requiring guaranteed 125°C operation and sub-millivolt accuracy.

FAQ
What is the maximum supply voltage for OPA2364AIDGKTG4?
The OPA2364AIDGKTG4 supports a supply voltage range of 1.8 V to 5.5 V across its V+ and V– terminals. Absolute maximum rating is 5.5 V; operation above this risks permanent damage. At 5.5 V, quiescent current rises to 1.4 mA per channel, so design margins should account for thermal dissipation in SOIC-8 packaging.
Does OPA2364AIDGKTG4 include a shutdown pin?
No, OPA2364AIDGKTG4 does not have a shutdown function. It is a dual op-amp without enable/disable control - unlike the pin-compatible OPA2363 family, which adds an enable pin per channel. For power-gated applications, external FET switching of V+ or use of OPA2363 is required.
Can OPA2364AIDGKTG4 drive capacitive loads directly?
Yes, OPA2364AIDGKTG4 is unity-gain stable and can drive up to 100 pF capacitive load without oscillation or excessive overshoot, as verified in Figure 13 of the SBOS259F datasheet. For loads >100 pF, isolation resistor (e.g., 10–50 Ω) between output and capacitance is recommended to maintain phase margin.
What is the input common-mode voltage range of OPA2364AIDGKTG4?
The input common-mode voltage range of OPA2364AIDGKTG4 extends from (V–) – 0.1 V to (V+) + 0.1 V, enabling true rail-to-rail input operation. This allows direct interfacing with sensors whose output spans the full supply range - such as resistive bridge outputs or DACs - without level-shifting circuitry.
Is OPA2364AIDGKTG4 qualified for automotive applications?
OPA2364AIDGKTG4 is specified for operation from –40°C to +125°C and meets industrial reliability standards, but it is not AEC-Q200 qualified. For automotive under-hood or safety-critical applications, TI recommends AEC-Q200-qualified alternatives like the OPA2991QDGKRQ1. OPA2364AIDGKTG4 is suitable for cabin-sensing modules where qualification is not mandated.
