Product details
Overview
OPA2364IDGKT 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, delivering 7-MHz gain-bandwidth, 5-V/µs slew rate, and 90-dB typical CMRR - ideal for low-voltage microphone preamplification and sensor signal conditioning in battery-powered systems.
For engineers reviewing the OPA2364IDGKT datasheet, OPA2364IDGKT pinout, OPA2364IDGKT application, or OPA2364IDGKT equivalent, key selection criteria include its dual-channel architecture, SOIC-8 package, 750-µA/channel quiescent current, ±10-pA input bias current, and rail-to-rail I/O swing within 10 mV of supply rails at 25°C.
Technical Context
The OPA2364IDGKT implements a complementary CMOS input stage that eliminates crossover distortion, enabling high common-mode rejection (90 dB typ) without degradation of differential linearity - critical for driving SAR and delta-sigma ADCs. Its unity-gain stable architecture supports active filter and transimpedance configurations with minimal phase shift up to 7 MHz.
No shutdown functionality is integrated; unlike the OPA2363 family, the OPA2364 variant operates continuously with no enable control pin. Input common-mode range extends from (V–) – 0.1 V to (V+) + 0.1 V, and output swings to within 10 mV of both rails under 10-kΩ load at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 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 at audio bandwidth (20 kHz) with >60° phase margin. |
| Slew Rate | 5 V/µs - ensures <1.5 µs settling to 0.01% for 4-V step inputs, suitable for fast-settling data acquisition front-ends. |
| Input Offset Voltage | 900 µV max (OPA2364I grade) - limits DC error to <4.5 mV in unity-gain buffer configuration at 5-V supply. |
| Quiescent Current | 750 µA per channel max - allows dual-amplifier operation on <1.5 mA total, extending battery life in portable sensors. |
| CMRR | 90 dB typical - rejects power-supply ripple and shared-noise coupling in mixed-signal PCB layouts. |
| Input Bias Current | ±10 pA max at 25°C - preserves signal integrity in high-impedance sources like electret microphones and piezoelectric sensors. |
Pinout & Package
OPA2364IDGKT 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 pitch. Thermal resistance RθJA is 125.3°C/W, supporting operation up to +125°C ambient.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads down to 10 kΩ while maintaining rail-to-rail swing (within 10 mV of V+ or V–). |
| 2 | –IN A | Inverting input for Channel A - accepts common-mode voltages from (V–) – 0.1 V to (V+) + 0.1 V. |
| 3 | +IN A | Noninverting input for Channel A - matched to –IN A for <900 µV offset and <3 µV/°C drift. |
| 4 | V– | Negative supply terminal - referenced to system ground in single-supply use; must be decoupled with 0.1-µF ceramic capacitor. |
| 5 | +IN B | Noninverting input for Channel B - electrically isolated from Channel A; supports independent gain configurations. |
| 6 | –IN B | Inverting input for Channel B - shares same input-stage topology and bias current spec as Channel A. |
| 7 | OUT B | Amplifier B output - identical AC/DC performance to OUT A; enables dual-path signal processing without cross-talk. |
| 8 | V+ | Positive supply terminal - accepts 1.8–5.5 V; PSRR is 80–330 µV/V across operating range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Output swings to within 10 mV of V+ and V–; input common-mode includes both supply rails - eliminates need for level-shifting in 1.8-V systems. |
| No phase reversal | Input stage avoids inversion during overdrive - prevents latch-up and transient errors when signals exceed supply rails. |
| Low input bias current | ±10 pA max enables use with >1-MΩ source impedances (e.g., electret mic bias networks) without significant DC error. |
| Unity-gain stable | Operates reliably with gain = 1; no external compensation required for buffer or inverting amplifier configurations. |
| Industrial temperature range | Specified from –40°C to +125°C - qualified for automotive cabin modules, industrial PLC analog inputs, and outdoor IoT sensors. |
Applications

Use Value: 90-dB CMRR rejects 50/60-Hz mains interference; ±10-pA input bias minimizes electrode polarization error in sub-µV signal paths. |
| Industrial Temperature Sensor Interface | Low-Power Active Filter Bank |
|
Use Scenario: Interfaces PT100 RTD bridge outputs in programmable logic controller (PLC) analog input modules operating from 24-V DC converted to 3.3-V local rail. IC Role / Device Role / Timing Role: One OPA2364IDGKT channel amplifies bridge differential voltage (gain = 100); second buffers reference voltage for ratiometric ADC conversion. Use Value: 7-MHz GBW supports fast step response (<1 µs) during sensor hot-swap events; 1.8-V minimum supply allows operation during brownout conditions. |
Use Scenario: Implements 2nd-order Sallen-Key low-pass filters (10-kHz cutoff) in battery-powered vibration analyzers using MEMS accelerometers. IC Role / Device Role / Timing Role: Each OPA2364IDGKT channel forms one filter stage - first as unity-gain buffer, second as gain-setting integrator with precision RC network. Use Value: Low noise (17 nV/√Hz) preserves SNR in 16-bit measurement; rail-to-rail output ensures full ADC code utilization without clipping. |
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 |
|---|---|---|---|
| OPA2365AIDGKT | Higher GBW (10 MHz), lower offset (120 µV max), but higher IQ (1.6 mA/channel); no extended temp grade. | Better for wideband active filters or fast-settling multiplexed DAQ; less suitable for ultra-low-power designs. | Select OPA2365AIDGKT when bandwidth >7 MHz or offset <500 µV is mandatory; accept 2.1× higher supply current. |
| MCP6022-I/SN | Lower GBW (10 MHz), higher IQ (1 mA/channel), wider offset range (2.5 mV max), and only rated to +85°C. | Cost-optimized for consumer-grade portable devices where industrial temp range and ultra-low bias current are not required. | Choose MCP6022-I/SN for cost-sensitive commercial applications below 85°C; avoid where <10-pA bias or 125°C operation is needed. |
Compared with OPA2364IDGKT, the OPA2365AIDGKT trades quiescent current for speed and precision, while the MCP6022-I/SN sacrifices temperature range and input bias performance for lower unit cost - making OPA2364IDGKT the optimal balance for industrial battery-powered signal chains requiring 1.8-V operation, 125°C rating, and sub-10-pA bias.

FAQ
What supply voltage range does the OPA2364IDGKT support?
The OPA2364IDGKT operates from a single supply of 1.8 V to 5.5 V - enabling direct compatibility with Li-ion batteries (3.0–4.2 V), coin cells (1.8–3.0 V), and standard 3.3-V logic rails. It does not require split supplies; V– is typically connected to ground in single-supply configurations. This range is fully specified across –40°C to +125°C.
Does the OPA2364IDGKT have a shutdown pin?
No, the OPA2364IDGKT does not include a shutdown function. Unlike the OPA2363 series, which adds an enable pin, the OPA2364IDGKT is a continuous-operation dual op amp with no power-control feature. All eight pins are dedicated to power, inputs, outputs, and NC functions - confirmed by the SOIC-8 pinout in the official datasheet (SBOS259F, Section 6).
What is the maximum input bias current specification for OPA2364IDGKT?
The OPA2364IDGKT has a maximum input bias current of ±10 pA at 25°C, with typical values near ±1 pA. This ultra-low bias enables accurate amplification of high-impedance sources such as electret microphone bias networks, pH electrodes, and photodiode transimpedance circuits without introducing significant DC error or leakage-induced drift.
Can OPA2364IDGKT drive capacitive loads?
Yes, the OPA2364IDGKT is stable with capacitive loads up to 100 pF in unity-gain configuration, as verified in the datasheet's Typical Characteristics (Figure 13). For loads exceeding 100 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended to maintain phase margin and prevent peaking or oscillation - especially in PCB traces longer than 2 cm.
Is OPA2364IDGKT pin-compatible with other OPAx364 variants?
The OPA2364IDGKT in SOIC-8 (D package) shares identical pinout with OPA2363IDGKT and OPA2364AIDGKT - all follow the standard dual-opamp SOIC layout: OUT A, –IN A, +IN A, V–, +IN B, –IN B, OUT B, V+. However, it is not pin-compatible with VSSOP-8 (DGK) variants due to different pad geometry and thermal pad presence, despite identical pin numbering.
