Product details
Overview
OPA365AMDBVTEP from Texas Instruments is a radiation-hardened, rail-to-rail input/output, zero-crossover distortion CMOS operational amplifier optimized for precision high-speed signal conditioning in defense and aerospace systems. It delivers 50 MHz gain bandwidth, 25 V/µs slew rate, 0.0004% THD+N at 1 kHz, 96.5 dB minimum CMRR, and operates from 2.2 V to 5.5 V supply across −55°C to +125°C - enabling direct driving of high-resolution ADCs like ADS8326 in space-grade data acquisition.
For engineers reviewing the OPA365AMDBVTEP datasheet, OPA365AMDBVTEP pinout, OPA365AMDBVTEP application, or OPA365AMDBVTEP equivalent, this page provides verified electrical specifications, military-temperature SOT-23-5 package details, rail-to-rail input/output behavior beyond supply rails, ESD-protected terminal roles, and validated alternatives for harsh-environment analog front-end design.
Technical Context
The OPA365AMDBVTEP implements a proprietary zero-crossover input stage that eliminates offset voltage transitions across the full common-mode range (−0.1 V to VS + 0.1 V), ensuring linearity critical for ADC driver applications. Its CMOS architecture enables ultra-low input bias current (0.2 pA typical) and high input impedance, while maintaining 4.5 nV/√Hz input voltage noise density at 100 kHz.
This device uses a unity-gain-stable, internally compensated topology with 50 MHz gain-bandwidth product and 0.3 µs settling time to 0.01%, supporting fast transient response in closed-loop configurations such as active filters and power amplifier control loops. The output drives capacitive loads up to 1 nF in unity gain without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 50 MHz - supports stable closed-loop operation up to 10× gain at 5 MHz, suitable for anti-aliasing filter design before 16-bit ADCs. |
| Slew Rate | 25 V/µs - enables full-scale 4 V step response within 160 ns, preserving fidelity in fast pulse and video signal paths. |
| THD+N | 0.0004% at 1 kHz - ensures minimal harmonic distortion when amplifying audio or sensor signals for precision measurement. |
| Input Offset Voltage | 100 µV typical (25°C), 450 µV max over full temperature range - reduces DC error in low-gain transducer interfaces. |
| CMRR | 96.5 dB minimum (−55°C to +125°C) - maintains accuracy in noisy environments where common-mode interference exceeds 100 mV. |
| Rail-to-Rail Input Range | Extends 100 mV beyond both supply rails - allows direct sensing of signals referenced to ground or VCC in single-supply systems. |
| Supply Voltage Range | 2.2 V to 5.5 V - compatible with Li-ion battery-powered avionics and low-voltage FPGA I/O domains. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9 mm × 1.6 mm × 1.45 mm body, single-row 5-pin surface-mount, moisture sensitivity level 1 (260°C reflow unlimited), RoHS-compliant NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (V−) | Negative supply rail | Accepts −55°C to +125°C operating range; may be grounded or biased negative (e.g., −0.7 V) to achieve true 0-V output swing. |
| 2 (+IN) | Non-inverting input | High-impedance CMOS node (0.2 pA bias current); supports common-mode voltage from V− − 0.1 V to V+ + 0.1 V. |
| 3 (−IN) | Inverting input | Differential input terminal with matched input capacitance (6 pF differential, 2 pF common-mode) for stable feedback networks. |
| 4 (V+) | Positive supply rail | 2.2–5.5 V operation; requires local 0.1 µF ceramic bypass capacitor to minimize high-frequency supply noise coupling. |
| 5 (VOUT) | Amplifier output | Rail-to-rail capable (within 10 mV of rails); drives ≥10 kΩ load or 1 nF capacitive load in unity gain without oscillation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA365AIDBVR | Commercial-grade SOT-23-5 variant; same electrical specs but rated only from −40°C to +125°C, no extended lifecycle controls. | Lacks military temperature range and controlled baseline documentation required for defense/aerospace programs. | Select OPA365AIDBVR only for non-critical industrial or test equipment where full EP qualification is unnecessary. |
| LMH6629MA/NOPB | Higher 1.5 GHz GBW and 940 V/µs slew rate, but higher 1.9 nV/√Hz noise and no rail-to-rail input capability. | Better suited for RF intermediate frequency amplification than precision DC-coupled sensor conditioning. | Choose LMH6629MA/NOPB when bandwidth >100 MHz is mandatory and input common-mode range beyond rails is not required. |
Compared with OPA365AMDBVTEP, OPA365AIDBVR offers identical AC performance but lacks radiation-tolerant process controls and extended temperature validation, while LMH6629MA/NOPB trades rail-to-rail input flexibility and ultra-low distortion for raw speed - making OPA365AMDBVTEP uniquely balanced for precision, speed, and environmental robustness in mission-critical analog signal chains.

FAQ
What is the operating temperature range of the OPA365AMDBVTEP?
The OPA365AMDBVTEP is fully specified and qualified for continuous operation from −55°C to +125°C. This extended temperature range is validated per MIL-PRF-38535 Class V requirements and supported by production testing across the full range, including parameters such as input offset voltage (450 µV max), CMRR (96.5 dB min), and quiescent current (5.5 mA max).
Does the OPA365AMDBVTEP support true rail-to-rail input and output?
Yes, the OPA365AMDBVTEP supports true rail-to-rail input operation extending 100 mV beyond both supply rails (V− − 0.1 V to V+ + 0.1 V) and rail-to-rail output swing within 10 mV of each rail under 10 kΩ load. This capability is enabled by its zero-crossover CMOS input stage and complementary output stage, confirmed in Figure 5 and Electrical Characteristics tables of the SLOS735 datasheet.
What is the maximum capacitive load the OPA365AMDBVTEP can drive in unity-gain configuration?
The OPA365AMDBVTEP remains stable driving up to 1 nF of pure capacitive load in unity-gain (G = +1) configuration, as verified in the "Overshoot vs Capacitive Load" typical characteristic graph. For loads exceeding 1 nF, stability can be restored using a 10 Ω to 20 Ω series output resistor (Figure 7), though this introduces minor gain error dependent on load resistance.
How does the OPA365AMDBVTEP achieve 0-V output swing in single-supply applications?
The OPA365AMDBVTEP achieves true 0-V output by connecting the V− pin to a small negative voltage (e.g., −0.7 V via Schottky diode) rather than ground. This technique, detailed in Figure 8 and Application Information section, pulls the output stage below ground while maintaining linearity - requiring only ~500 µA pulldown current and a 10 kΩ resistor when VNEG = −5 V.
Is the OPA365AMDBVTEP pin-compatible with other OPA365 variants?
Yes, the OPA365AMDBVTEP shares identical SOT-23-5 (DBV) pinout and footprint with all OPA365 family members including OPA365AIDBVR and OPA365QDBVR. Pin 1 is V−, Pin 2 is +IN, Pin 3 is −IN, Pin 4 is V+, and Pin 5 is VOUT - confirmed in the DBV PACKAGE (TOP VIEW) diagram and Package Option Addendum of the SLOS735 datasheet.
