Product details
Overview
OPA2364AIDGKR from Texas Instruments is a dual-channel, rail-to-rail input/output CMOS operational amplifier optimized for single-supply operation from 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 pA input bias current and 500 µV max input offset voltage - enabling precision signal conditioning in battery-powered sensor interfaces and portable audio preamplifiers.
For engineers reviewing the OPA2364AIDGKR datasheet, OPA2364AIDGKR pinout, OPA2364AIDGKR application, or OPA2364AIDGKR equivalent, key selection criteria include its dual-channel VSSOP-8 package, 750 µA/channel quiescent current at 1.8 V, rail-to-rail I/O swing within 20 mV of supply rails, and guaranteed operation from –40°C to +125°C for industrial-grade embedded systems.
Technical Context
The OPA2364AIDGKR implements a complementary CMOS input stage that eliminates crossover distortion and maintains high CMRR across the full common-mode range (–0.1 V to VS + 0.1 V), ensuring linearity when driving SAR ADCs. Its unity-gain stable architecture supports low-noise active filtering without external compensation.
No shutdown function is integrated - unlike the OPA2363 family - making it a dedicated dual op-amp without enable control. The device uses a regulated charge-pump topology internally to support rail-to-rail output swing even at 1.8-V supply, with output capable of sourcing/sinking ≥±60 mA under short-circuit conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - 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 at audio frequencies up to 700 kHz with <0.1% settling. |
| Input Offset Voltage (max) | 500 µV - ensures ≤0.5% error in 1-V full-scale sensor amplification without trimming. |
| Quiescent Current / Channel | 750 µA (max at 1.8 V) - allows dual-amplifier operation on microamp-level power budgets in always-on monitoring nodes. |
| CMRR (typ) | 90 dB - rejects >99.988% of common-mode noise from noisy PCB environments or shared ground paths. |
| Output Swing (RL = 10 kΩ) | Within 20 mV of rails - preserves dynamic range in 1.8-V systems where headroom is constrained to <200 mV. |
| Input Bias Current (max) | ±10 pA - permits use with high-impedance sources (e.g., piezoelectric sensors, pH electrodes) without significant DC error. |
Pinout & Package
OPA2364AIDGKR is housed in an 8-pin VSSOP (DGK) package measuring 3.0 mm × 3.0 mm, with 0.5-mm lead pitch and exposed thermal pad. This thermally enhanced, surface-mount package supports high-density layout while maintaining low junction-to-board resistance (92.4 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream ADC input or filter network; rail-to-rail swing supports full 1.8-V signal range. |
| 2 | –IN A | Inverting input for channel A - used in transimpedance or inverting gain configurations; accepts signals down to V– – 0.1 V. |
| 3 | +IN A | Noninverting input for channel A - enables high-Z buffer or differential sensing; common-mode range includes both supply rails. |
| 4 | V– | Negative supply terminal - tied to ground in single-supply systems; serves as reference for input/output swing. |
| 5 | –IN B | Inverting input for channel B - electrically isolated from channel A; supports independent signal paths on same die. |
| 6 | +IN B | Noninverting input for channel B - identical electrical specs to +IN A; no crosstalk between channels (130 dB @ 1 kHz). |
| 7 | OUT B | Amplifier B output - independently buffered; usable for dual-path signal processing or stereo audio preamp stages. |
| 8 | V+ | Positive supply terminal - accepts 1.8–5.5 V; internal charge pump enables rail-to-rail output even at minimum supply. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range extends 0.1 V beyond both rails; output swings to within 20 mV of V+ and V– at 10-kΩ load. |
| Low input bias current | ±10 pA max at 25°C - minimizes voltage error across high-value feedback resistors (>1 MΩ) in precision integrators. |
| High CMRR | 90 dB typical - maintains accuracy in single-ended sensor bridges where common-mode noise exceeds signal amplitude. |
| Unity-gain stability | No external compensation required - simplifies design of gain-of-1 buffers, active filters, and voltage followers. |
| Wide temperature range | Specified from –40°C to +125°C - suitable for under-hood automotive modules, industrial PLC I/O, and outdoor IoT sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDGKR | Chopper-stabilized architecture; 10 µV max offset, 0.1 µV/°C drift, but 350-kHz GBW and higher 17-µA quiescent current. | Better DC precision for ultra-low-drift sensor front-ends; unsuitable for audio or >100-kHz signal paths. | Select OPA2333AIDGKR only when offset drift dominates over bandwidth and power constraints. |
| MCP6022-I/SN | 10-MHz GBW, 2.3-V to 5.5-V supply, but 1.5-mV max offset, 100-pA bias current, and 100-µA quiescent current per channel. | Higher speed and lower cost, but insufficient DC accuracy for precision bridge amplification or low-current transimpedance. | Choose MCP6022-I/SN for cost-sensitive, medium-accuracy applications where 1.5-mV offset is acceptable. |
Compared with OPA2364AIDGKR, OPA2333AIDGKR trades bandwidth and power efficiency for ultra-low drift, while MCP6022-I/SN offers higher speed at the expense of DC precision and quiescent current - making OPA2364AIDGKR optimal for balanced performance in 1.8–5.5-V industrial and portable systems.

FAQ
What is the maximum supply voltage for OPA2364AIDGKR?
The OPA2364AIDGKR supports a maximum supply voltage of 5.5 V across the V+ to V– terminals. Absolute maximum ratings specify that exceeding this voltage - even momentarily - may cause permanent damage. Operation above 5.5 V violates the device's absolute maximum conditions and voids parametric guarantees; for 5-V systems, ensure decoupling and transient suppression to prevent overshoot beyond 5.5 V.
Does OPA2364AIDGKR include a shutdown pin?
No, OPA2364AIDGKR does not include a shutdown pin. It is a dual-channel operational amplifier without enable/disable functionality. The OPA2363 family (e.g., OPA2363AIDGSR) provides shutdown capability via dedicated enable pins, but OPA2364AIDGKR is optimized for continuous operation with lower quiescent current and simplified pinout - confirming absence of shutdown logic in its functional block diagram and pin configuration tables.
What is the input common-mode voltage range of OPA2364AIDGKR?
The input common-mode voltage range of OPA2364AIDGKR extends from (V–) – 0.1 V to (V+) + 0.1 V, enabling true rail-to-rail input operation. This specification is verified across the full –40°C to +125°C temperature range and applies to both inverting and noninverting inputs. At 1.8-V supply, inputs accept signals from –0.1 V to +1.9 V, supporting direct connection to transducers with negative excursions or overvoltage transients.
Can OPA2364AIDGKR drive capacitive loads?
OPA2364AIDGKR can drive capacitive loads up to 100 pF while maintaining stability and specified settling time (1 µs for 0.1%). For loads >100 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended to prevent peaking or oscillation. TI's datasheet Figure 13 confirms <5% overshoot at 100-pF load; larger capacitors require careful layout and potential compensation per Application Report SBAA213.
Is OPA2364AIDGKR pin-compatible with other dual op-amps in VSSOP-8?
OPA2364AIDGKR uses a standard VSSOP-8 pinout (DGK) matching industry conventions: pins 1/7 = outputs, 2/5 = inverting inputs, 3/6 = noninverting inputs, 4 = V–, 8 = V+. It is pin-compatible with TLV2462, MCP6022, and LMV358 in the same package - but functional differences (e.g., bandwidth, offset, rail-to-rail behavior) require validation. Always verify input/output voltage ranges and quiescent current against target application requirements before substitution.
