Product details
Overview
OPA4364AIDRG4 from Texas Instruments is a quad, rail-to-rail input/output CMOS operational amplifier optimized for low-voltage, single-supply operation (1.8 V to 5.5 V). It delivers 7 MHz gain-bandwidth, 5 V/µs slew rate, 90 dB typical CMRR, ≤500 µV max input offset voltage, and 750 µA/channel quiescent current - enabling high-fidelity signal conditioning in battery-powered sensor interfaces and portable audio preamplifiers.
For engineers reviewing the OPA4364AIDRG4 datasheet, OPA4364AIDRG4 pinout, OPA4364AIDRG4 application, or OPA4364AIDRG4 equivalent, key selection considerations include its 14-pin SOIC package, rail-to-rail I/O swing within 10 mV of rails, −40°C to +125°C industrial temperature rating, and compatibility with electret microphone biasing and active filter topologies requiring low THD+N (0.002%) and wide common-mode range (V− − 0.1 V to V+ + 0.1 V).
Technical Context
The OPA4364AIDRG4 employs a complementary CMOS input stage that eliminates crossover distortion and associated CMRR degradation, ensuring stable differential linearity when driving SAR and delta-sigma ADCs. Its unity-gain stability and 7 MHz GBW support precision closed-loop configurations including 2nd-order Sallen-Key filters and transimpedance amplifiers for photodiode or microphone front-ends.
Each of the four independent amplifiers features identical electrical characteristics: input bias current ≤±10 pA at 25°C, input voltage noise density 17 nV/√Hz at 10 kHz, open-loop gain ≥90 dB (typ), and output capable of sourcing/sinking ≥±30 mA while maintaining rail-to-rail swing under 10 kΩ load.
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 unity-gain and G = 10 configurations up to ~700 kHz with <0.1% settling in 1 µs. |
| Slew Rate | 5 V/µs - preserves fidelity of fast transient signals such as pulse-width modulated sensor outputs or audio peaks. |
| Input Offset Voltage | ≤500 µV (max) - minimizes DC error in precision instrumentation amplifiers and bridge sensor conditioning circuits. |
| CMRR | 90 dB (typ), 74 dB (min) - rejects power-supply ripple and common-mode noise in noisy industrial environments. |
| Quiescent Current | 750 µA per channel (max) - allows four-channel analog signal processing in ultra-low-power IoT endpoints with sub-3 mA total IQ. |
| Output Swing | Within 10 mV of rails (RL = 10 kΩ) - maximizes dynamic range in 1.8 V–3.3 V ADC-driven systems. |

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Operates with common-mode input down to V− − 0.1 V and up to V+ + 0.1 V; output swings within 10 mV of both rails - preserves full ADC code utilization in low-voltage systems. |
| No phase reversal | Eliminates output polarity inversion during input overdrive - prevents latch-up or erroneous control signals in closed-loop motor or valve drivers. |
| Low input bias current | ≤±10 pA at 25°C - enables high-impedance sensor interfacing (e.g., pH electrodes, piezoelectric elements) without significant DC error. |
| High CMRR without crossover | 90 dB typical CMRR maintained across frequency - ensures accurate differential measurement in presence of EMI or supply noise. |
| Unity-gain stable | No external compensation required for G = 1 - simplifies design of voltage followers, active filters, and buffer stages. |
Applications
| Portable Electret Microphone Preamplifier | Multi-Sensor Signal Conditioning |
|---|---|
Use Scenario: Amplifying weak AC-coupled signals from electret microphones in voice-controlled IoT devices powered by 3.3 V LDOs. IC Role / Device Role / Timing Role: Quad OPA4364AIDRG4 provides individual biasing (RBIAS), AC coupling (CIN), gain (RFB/RDIV), and filtering (CFB, CDIV) for four independent mic channels. Use Value: 0.002% THD+N and 17 nV/√Hz noise ensure clean audio capture; rail-to-rail output maximizes SNR into 16-bit ADCs. | Use Scenario: Simultaneous amplification and level-shifting of four resistive bridge sensors (e.g., pressure, temperature, strain) in industrial PLC modules. IC Role / Device Role / Timing Role: Each amplifier configures as an instrumentation-grade difference amplifier with matched external resistors, sharing V+ and V− rails. Use Value: 500 µV max VOS and 3 µV/°C drift minimize calibration burden; 74–90 dB CMRR rejects shared supply noise across all channels. |
| Low-Voltage Active Filter Bank | ADC Driver for Precision Data Acquisition |
Use Scenario: Implementing cascaded 2nd-order low-pass and band-pass filters in handheld test equipment operating from 1.8 V batteries. IC Role / Device Role / Timing Role: Two OPA4364AIDRG4 channels form Sallen-Key topology per filter; remaining two handle signal buffering and reference generation. Use Value: 7 MHz GBW supports filter cutoffs up to 1 MHz; unity-gain stability avoids oscillation with ceramic feedback networks. | Use Scenario: Driving SAR ADC inputs (e.g., ADS8860) in medical ECG front-ends requiring <1 LSB error at 16-bit resolution. IC Role / Device Role / Timing Role: Single OPA4364AIDRG4 channel configured as unity-gain buffer with 100 pF capacitive load drive capability. Use Value: 1 µs 0.1% settling time and 5 V/µs slew rate meet 1 MSPS sampling requirements; 90 dB CMRR suppresses common-mode interference from lead-wire pickup. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4364IDR | Same electrical specs and pinout; differs only in tape-and-reel packaging (DR vs IDR) and RoHS compliance marking. | No functional difference; suitable for identical PCB layouts and thermal designs. | Select OPA4364IDR for standard TI distribution channels where OPA4364AIDRG4 is unavailable. |
| TLV9064IPWR | Higher 10 MHz GBW and 6.5 V/µs slew rate; 500 µV max VOS unchanged; 1.8–5.5 V supply compatible. | Better suited for higher-speed active filters or faster-settling ADC drivers; slightly higher IQ (1.1 mA/ch). | Choose TLV9064IPWR when bandwidth >7 MHz or settling time <1 µs is required; verify layout for increased PSRR sensitivity. |
Compared with OPA4364AIDRG4, OPA4364IDR offers identical performance in alternate packaging, while TLV9064IPWR trades modestly higher power for improved speed - making it preferable for time-critical signal paths but less optimal for ultra-low-power always-on sensing nodes.

FAQ
What is the maximum supply voltage for OPA4364AIDRG4?
The OPA4364AIDRG4 supports a maximum supply voltage of 5.5 V across V+ and V− pins. Absolute maximum ratings specify (V+ − V−) ≤ 5.5 V; operation beyond this risks permanent damage. For robust long-term reliability in industrial environments, TI recommends limiting supply to 5.0 V with proper decoupling.
Does OPA4364AIDRG4 include shutdown functionality?
No, the OPA4364AIDRG4 does not feature a shutdown pin. Shutdown capability is exclusive to the OPA363 family (e.g., OPA363). The OPA4364AIDRG4 operates continuously when powered; quiescent current remains at 750 µA per channel under all operating conditions.
Can OPA4364AIDRG4 drive a 100-pF capacitive load stably?
Yes, the OPA4364AIDRG4 is specified to drive up to 100 pF capacitive loads with minimal overshoot and 1 µs 0.1% settling time. Typical characteristics confirm stable step response under CL = 100 pF, G = 1, making it suitable for driving ADC input capacitors and long PCB traces without external isolation resistors.
What is the input common-mode voltage range of OPA4364AIDRG4?
The input common-mode voltage range of OPA4364AIDRG4 extends from (V− − 0.1 V) to (V+ + 0.1 V) across the full supply range (1.8 V to 5.5 V). This rail-to-rail input capability allows direct interfacing with sensors whose output spans near ground or near V+, such as thermocouples or resistive dividers.
Is OPA4364AIDRG4 pin-compatible with other quad op-amps like LM324?
No, OPA4364AIDRG4 is not pin-compatible with LM324 or other legacy quad op-amps. Its 14-pin SOIC pinout places V+ (Pin 4), V− (Pins 8 and 11), and individual input/output terminals differently than LM324's 14-pin layout. Direct replacement requires PCB redesign to accommodate distinct channel mapping and supply pin locations.
