Product details
Overview
5962-0051203QHA from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier qualified for high-reliability military and aerospace applications under QML-38535 Class Q. It delivers 6.4 MHz gain-bandwidth product, ±80 mA output drive, 1.6 V/µs slew rate, 100 µV input offset voltage, and 11 nV/√Hz input noise voltage at 1 kHz, enabling precision signal conditioning in low-voltage analog front-ends of avionics sensor interfaces.
For engineers reviewing the 5962-0051203QHA datasheet, 5962-0051203QHA pinout, 5962-0051203QHA application, or 5962-0051203QHA equivalent, this device is selected for its guaranteed −55°C to 125°C operation, micropower shutdown mode (0.3 µA/channel), rail-to-rail swing into 10 kΩ loads, and qualification to MIL-PRF-38535 with configuration control and radiation tolerance documentation.
Technical Context
The 5962-0051203QHA implements a CMOS input stage with rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing, supporting full dynamic range in single-supply systems down to 2.7 V. Its internal architecture enables stable unity-gain operation with ≥44° phase margin at 160 pF capacitive load and 10 kΩ load resistance.
It features an active shutdown terminal (SHDN) that places the amplifier in ultralow-current mode (≤0.3 µA/channel) while forcing the output into high-impedance state-critical for power-gated subsystems in space-grade telemetry chains and redundant flight control signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - Enables stable closed-loop operation up to ~1 MHz with gain ≥6 in sensor amplification stages. |
| Slew Rate | 1.6 V/µs - Supports 12-bit ADC buffering at 100 kSPS without distortion in data acquisition modules. |
| Input Offset Voltage | 100 µV (typ) - Ensures ≤0.002% gain error in precision current-sense amplifiers at room temperature. |
| Output Drive | ±80 mA - Drives 50 Ω transmission lines or multiple CMOS inputs directly without external buffers. |
| Supply Current | 500 µA/channel - Allows continuous operation in battery-backed health-monitoring circuits for >10 years on coin cells. |
| Shutdown Current | 0.3 µA/channel - Reduces system standby power to sub-microwatt levels during dormant satellite orbital phases. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - Maintains SNR > 90 dB in low-level thermocouple or strain-gauge signal chains. |
Pinout & Package
Ceramic flatpack (U) package, 10-pin, hermetically sealed, lead-free finish, qualified per MIL-STD-883.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - electrically isolated; used for mechanical alignment and thermal relief. |
| 2 | NC | No internal connection - reserved for future die revision; must remain unconnected. |
| 3 | IN− | Inverting input - accepts differential feedback signals; high-impedance CMOS node (10⁹ Ω typical). |
| 4 | IN+ | Non-inverting input - supports rail-to-rail common-mode range (0 V to VDD); matched to IN− for low VIO. |
| 5 | GND | Analog ground reference - primary return path for input bias and output current; requires dedicated low-impedance plane. |
| 6 | NC | No internal connection - isolation barrier between input and output sections; no routing required. |
| 7 | SHDN | Active-high shutdown control - drives output to high-Z when <0.7 V; ≥2 V required to enable operation. |
| 8 | VDD | Positive supply rail - operates from 2.7 V to 6 V; decoupling capacitor (100 nF) mandatory at pin. |
| 9 | OUTPUT | Amplifier output - rail-to-rail swing capability; capable of sourcing/sinking ±80 mA into resistive loads. |
| 10 | NC | No internal connection - thermal pad tie point; may be connected to ground plane for improved thermal dissipation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333MDREP | Chopper-stabilized architecture; 0.02 µV/°C drift vs. 2 µV/°C for 5962-0051203QHA; higher IDD (17 µA) but zero VIO drift. | Better for ultra-low-drift DC applications (e.g., precision reference buffers); not qualified to QML-38535 Class Q. | Select when long-term VIO stability dominates over radiation tolerance and military screening. |
| LM10CJ/883 | Older bipolar design; wider VDD range (±1.1 V to ±20 V); higher VIO (200 µV typ); no rail-to-rail output. | Compatible with legacy ±15 V avionics buses; lacks shutdown and modern noise performance. | Select only for drop-in replacement in existing LM10-based designs requiring minimal layout change. |
Compared with OPA2333MDREP and LM10CJ/883, the 5962-0051203QHA uniquely balances QML Class Q qualification, rail-to-rail operation, micropower shutdown, and 6.4 MHz bandwidth-making it the only choice for new radiation-tolerant, low-voltage, high-reliability analog signal paths.

FAQ
What is the absolute maximum supply voltage rating for the 5962-0051203QHA?
The 5962-0051203QHA has an absolute maximum supply voltage of 6 V, as specified in the Absolute Maximum Ratings table. Operation beyond this limit risks permanent damage. Recommended operating range is 2.7 V to 6 V, with full electrical performance guaranteed across this span for the −55°C to 125°C temperature range.
Does the 5962-0051203QHA support true rail-to-rail input and output operation?
Yes, the 5962-0051203QHA supports rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 10 mV of rails at 10 kΩ load). This is confirmed in the device description and electrical characteristics tables, enabling full utilization of supply headroom in low-voltage systems such as 3.3 V avionics buses.
What is the guaranteed input offset voltage specification for the 5962-0051203QHA over temperature?
The 5962-0051203QHA guarantees a maximum input offset voltage of 1700 µV over its full operating temperature range of −55°C to 125°C, with a typical value of 500 µV at 25°C. The temperature coefficient is specified at 2 µV/°C, ensuring predictable drift behavior in thermal cycling environments.
How does the shutdown function operate on the 5962-0051203QHA?
The 5962-0051203QHA's SHDN pin is active-high: applying ≥2 V enables normal operation, while ≤0.7 V places the amplifier in shutdown mode with supply current reduced to ≤0.3 µA/channel and output forced to high-impedance state. This behavior is verified in the Electrical Characteristics table under IDD(SHDN) test conditions.
Is the 5962-0051203QHA qualified to MIL-PRF-38535 Class Q?
Yes, the 5962-0051203QHA is fully qualified to MIL-PRF-38535 Class Q per its part number suffix "QHA", indicating compliance with QML requirements including screening, lot traceability, configuration control, and radiation tolerance documentation-verified in TI's official QML listing and datasheet qualification statements.
