Product details
Overview
OPA2364IDR 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 ≤900 µV maximum input offset voltage across –40°C to +125°C, serving as a precision signal conditioner in battery-powered sensor interfaces and data acquisition front-ends.
For engineers reviewing the OPA2364IDR datasheet, OPA2364IDR pinout, OPA2364IDR application, or OPA2364IDR equivalent, key selection considerations include its dual-channel rail-to-rail I/O performance at ultra-low supply voltage, low 750 µA/channel quiescent current, and guaranteed operation over extended industrial temperature range - critical for portable instrumentation and automotive body electronics.
Technical Context
The OPA2364IDR employs a complementary CMOS input stage that eliminates crossover distortion, enabling high common-mode rejection (90 dB typ.) without degradation of differential linearity when driving SAR or delta-sigma ADCs. Its unity-gain stable architecture supports gain configurations from –1 to +10 with minimal phase margin loss.
Designed for single-supply systems, the device accepts input common-mode voltages from (V–) – 0.1 V to (V+) + 0.1 V and delivers output swing within 20 mV of both rails under full load. It draws only 750 µA per channel at 5.5 V supply and maintains 7 MHz gain-bandwidth product across 1.8–5.5 V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 7 MHz - supports accurate amplification of signals up to ~1 MHz in closed-loop G=10 configuration. |
| CMRR | 90 dB (typical) - rejects power supply noise and common-mode interference in noisy embedded environments. |
| Slew Rate | 5 V/µs - enables faithful reproduction of fast transients in active filter and sensor signal chain stages. |
| Input Offset Voltage | ≤900 µV (max) - ensures <±1 LSB error when conditioning mV-level sensor outputs into 12-bit ADCs. |
| Quiescent Current | 750 µA/channel (max) - allows dual-channel precision amplification in always-on battery-powered nodes. |
| Rail-to-Rail I/O | Input: (V–) – 0.1 V to (V+) + 0.1 V; Output: within 20 mV of rails - maximizes dynamic range on 3.3 V or lower supplies. |
| Supply Range | 1.8 V to 5.5 V - interoperable with Li-ion, coin-cell, and regulated 3.3 V/2.5 V system rails. |
Pinout & Package
OPA2364IDR is packaged in an 8-pin SOIC (D package) with 4.90 mm × 3.91 mm body size, rated for –40°C to +125°C operation. Thermal resistance RθJA = 125.3°C/W enables reliable performance in compact PCB layouts without forced airflow.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream ADC input or next-stage filter with rail-to-rail swing. |
| 2 | –IN A | Inverting input for channel A - used in transimpedance or inverting gain configurations. |
| 3 | +IN A | Noninverting input for channel A - accepts high-impedance sensor signals (e.g., thermopile, bridge). |
| 4 | V– | Negative supply terminal - connects to ground or lowest system potential; supports true single-supply use. |
| 5 | –IN B | Inverting input for channel B - enables dual-sensor differential measurement or stereo signal path. |
| 6 | +IN B | Noninverting input for channel B - isolated reference path for second analog channel. |
| 7 | OUT B | Amplifier B output - independent output for parallel signal processing or redundancy. |
| 8 | V+ | Positive supply terminal - accepts 1.8–5.5 V; internal regulation ensures stable biasing across voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 1.8–5.5 V supply range - no level-shifting required for microcontroller ADC interfacing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C drift vs. OPA2364IDR's 3 µV/°C; higher 350 kHz GBW but lower 1.6 V/µs slew rate. | Better for DC-critical applications (e.g., weigh scales); less suitable for >100 kHz signal conditioning. | Select OPA2333AIDR when long-term offset stability dominates speed requirements. |
| MCP6022-I/SN | Lower 10 MHz GBW but higher 2.25 mA/quiescent current; 2.5 mV max VOS; not specified beyond 85°C. | Cost-optimized for commercial-temp consumer devices; lacks extended temperature validation. | Choose MCP6022-I/SN only for non-automotive, non-industrial cost-sensitive designs with relaxed accuracy. |
Compared with OPA2364IDR, OPA2333AIDR trades bandwidth and slew rate for near-zero drift, while MCP6022-I/SN sacrifices temperature range and offset performance for unit cost - making OPA2364IDR the balanced choice for industrial-grade dual-channel signal chains requiring speed, precision, and ruggedness.

FAQ
What is the maximum operating temperature for OPA2364IDR?
The OPA2364IDR is fully specified and tested from –40°C to +125°C ambient temperature. This extended industrial temperature range is validated per TI's production test flow and supports deployment in under-hood automotive, motor drive, and outdoor industrial equipment where thermal stress is significant. The SOIC package's RθJA of 125.3°C/W ensures safe junction temperatures under typical PCB copper pour conditions.
Does OPA2364IDR support true single-supply operation below 2.0 V?
Yes, OPA2364IDR operates down to 1.8 V supply voltage with full functionality - including rail-to-rail input common-mode range (V– – 0.1 V to V+ + 0.1 V) and output swing within 20 mV of both rails. At 1.8 V, it maintains 7 MHz GBW and 5 V/µs slew rate, enabling precision amplification in energy-harvesting and coin-cell-powered systems where every millivolt counts.
Is OPA2364IDR pin-compatible with other devices in the OPAx364 family?
No - OPA2364IDR (dual, 8-pin SOIC) shares pinout with OPA2363IDR and OPA2364AIDR in the same package, but differs from OPA364 (single, 5-pin SOT-23) and OPA4364 (quad, 14-pin SOIC/TSSOP). Pin compatibility is limited to same-channel-count variants in identical packages; cross-family substitution requires layout revision.
What is the typical input bias current of OPA2364IDR and why does it matter?
OPA2364IDR exhibits ±1 pA typical input bias current at 25°C, rising to ±10 pA over –40°C to +125°C. This ultra-low value prevents significant voltage drop across high-impedance feedback or sensor networks (e.g., >10 MΩ), preserving gain accuracy in photodiode transimpedance amps, pH electrode buffers, and high-resistance thermistor interfaces where leakage would otherwise dominate error.
Can OPA2364IDR drive capacitive loads without oscillation?
OPA2364IDR is unity-gain stable and characterized to drive ≥100 pF capacitive loads with minimal overshoot (<10%) and settling time ≤1.5 µs (0.01%). For loads >200 pF, TI recommends adding a small series resistor (10–50 Ω) between output and capacitance to maintain phase margin - a standard practice documented in the datasheet's Layout section for robust high-frequency stability.
