Product details
Overview
OPA2364AIDRG4 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, with ±10-pA input bias current and 500-µV maximum input offset voltage. It is used in battery-powered sensor signal conditioning and microphone preamplification circuits.
For engineers reviewing the OPA2364AIDRG4 datasheet, OPA2364AIDRG4 pinout, OPA2364AIDRG4 application, or OPA2364AIDRG4 equivalent, key selection criteria include rail-to-rail I/O swing within 10 mV of rails, low 750-µA/channel quiescent current at 5.5 V, and guaranteed operation from –40°C to +125°C in industrial environments.
Technical Context
The OPA2364AIDRG4 employs a complementary CMOS input stage that eliminates crossover distortion, enabling high common-mode rejection (90 dB typ.) without degradation of THD or differential linearity when driving ADCs. Its unity-gain stable architecture supports precision active filtering and low-noise amplification down to 1.8-V supply.
It features rail-to-rail input common-mode range (V– – 0.1 V to V+ + 0.1 V) and output swing to within 10 mV of both rails under 10-kΩ load. Input voltage noise is 17 nV/√Hz at 10 kHz, and input capacitance is 2 pF differential / 3 pF common-mode - critical for high-impedance sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.8 V to 5.5 V single supply - enables direct interface with Li-ion, coin-cell, and 3.3-V logic systems without level-shifting. |
| Gain-Bandwidth Product | 7 MHz - supports stable closed-loop gain ≥10 up to ~700 kHz, suitable for anti-aliasing and audio-band filters. |
| Slew Rate | 5 V/µs - ensures <1.5 µs settling to 0.01% for 4-V steps, critical for fast data acquisition front-ends. |
| Input Offset Voltage | ≤500 µV (max) - minimizes DC error in precision transducer amplification without external trimming. |
| Quiescent Current | 750 µA per channel (max) at 5.5 V - balances speed and ultra-low power for always-on sensing nodes. |
| CMRR | 90 dB (typical), 74 dB (min) - rejects supply and reference noise in single-supply mixed-signal systems. |
| Operating Temperature | –40°C to +125°C - qualified for automotive cabin, industrial motor control, and outdoor IoT sensor enclosures. |
Pinout & Package
OPA2364AIDRG4 is packaged in an 8-pin SOIC (D package) with 4.90 mm × 3.91 mm body size. Pin 1 is OUT A, Pin 2 is –IN A, Pin 3 is +IN A, Pin 4 is V–, Pin 5 is –IN B, Pin 6 is +IN B, Pin 7 is OUT B, and Pin 8 is V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream stages or ADC inputs; rail-to-rail swing supports full-scale digitization. |
| 2 | –IN A | Inverting input, Channel A - accepts feedback network for precise gain configuration (e.g., inverting amplifier). |
| 3 | +IN A | Noninverting input, Channel A - connects to high-impedance sensors (e.g., electret mic bias node) with minimal loading. |
| 4 | V– | Negative supply terminal - tied to ground in single-supply systems; establishes reference for rail-to-rail input common-mode range. |
| 5 | –IN B | Inverting input, Channel B - independent signal path for dual-channel applications like stereo audio or differential sensor pairs. |
| 6 | +IN B | Noninverting input, Channel B - electrically isolated from Channel A; supports separate biasing and signal routing. |
| 7 | OUT B | Amplifier B output - provides second analog channel without cross-talk; verified >130-dB channel separation at DC. |
| 8 | V+ | Positive supply terminal - accepts 1.8–5.5 V; internal regulation ensures stable performance across supply variation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Output swings to within 10 mV of V– and V+, and input accepts signals from V– – 0.1 V to V+ + 0.1 V - eliminates need for dual supplies in portable systems. |
| No phase reversal | Guaranteed absence of output polarity inversion during input overdrive - prevents latch-up or false triggering in safety-critical monitoring. |
| Low input bias current | ±1 pA typ., ±10 pA max - preserves signal integrity in high-Z source applications (e.g., piezoelectric sensors, pH electrodes). |
| Unity-gain stable | Operates stably with gain = 1 without external compensation - simplifies design of buffer, follower, and gain-of-one signal conditioning stages. |
| Low THD+N | 0.002% at 20 Hz–20 kHz (G = 1, VS = 5 V) - meets audio-grade fidelity requirements for voice capture and acoustic sensing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2364AIDR | Same silicon die and specifications; differs only in tape-and-reel packaging (DR vs DRG4) - identical electrical and thermal behavior. | No functional difference; DRG4 denotes green (lead-free) RoHS-compliant packaging with moisture sensitivity level 2a. | Select OPA2364AIDRG4 for automated SMT assembly requiring RoHS compliance and humidity-safe handling. |
| MCP6022-I/SN | Lower bandwidth (10 MHz), higher quiescent current (1 mA/ch), no guaranteed 125°C operation - wider supply range (2.7–5.5 V). | Not rated for extended temperature; less suitable for under-hood or industrial edge nodes requiring full –40°C to +125°C validation. | Choose MCP6022-I/SN only if 10-MHz GBW is required and ambient temperature stays below 85°C. |
Compared with OPA2364AIDR, OPA2364AIDRG4 offers identical performance with enhanced environmental compliance; versus MCP6022-I/SN, it delivers superior thermal robustness and lower power at the cost of 3-MHz less bandwidth - making it optimal for precision, high-reliability, low-power dual-channel analog front-ends.

FAQ
What is the maximum supply voltage for OPA2364AIDRG4?
The OPA2364AIDRG4 supports a maximum supply voltage of 5.5 V across V+ and V– terminals. Absolute maximum ratings specify that the voltage difference ([V+] – [V–]) must not exceed 5.5 V, and operation above this risks permanent damage. The device is fully specified from 1.8 V to 5.5 V, with optimal performance at 3.3 V and 5 V.
Does OPA2364AIDRG4 include shutdown functionality?
No, OPA2364AIDRG4 does not include shutdown functionality. Shutdown is available only in the OPA2363 variant (e.g., OPA2363AIDGSR), which adds dedicated enable pins. The OPA2364AIDRG4 is a dual-channel, non-shutdown op-amp - all channels remain active whenever power is applied.
What is the input offset voltage specification for OPA2364AIDRG4?
The OPA2364AIDRG4 has a maximum input offset voltage of 500 µV at TA = 25°C and VS = 5 V. This is guaranteed across the full –40°C to +125°C temperature range for the "I" grade. Drift is limited to 3 µV/°C, ensuring predictable DC error in precision sensor amplification circuits.
Can OPA2364AIDRG4 drive capacitive loads directly?
Yes, OPA2364AIDRG4 can drive moderate capacitive loads. Typical characterization shows stable operation with ≤100 pF without external isolation resistance. For loads >100 pF, a small series resistor (e.g., 10–50 Ω) between the output and capacitor is recommended to maintain phase margin and prevent peaking or oscillation.
Is OPA2364AIDRG4 pin-compatible with other dual op-amps in SOIC-8?
OPA2364AIDRG4 uses a standard SOIC-8 pinout matching industry conventions: Pin 1 = OUT A, Pin 2 = –IN A, Pin 3 = +IN A, Pin 4 = V–, Pin 5 = –IN B, Pin 6 = +IN B, Pin 7 = OUT B, Pin 8 = V+. It is pin-compatible with TL072, RC4558, and MCP6022 in SOIC-8 packages for drop-in replacement where bandwidth, noise, and rail-to-rail performance align.
