Product details
Overview
5962-9460203QCA from Texas Instruments is a military-grade, high-speed, low-noise JFET-input operational amplifier in the TLE207x family. It delivers 10 MHz unity-gain bandwidth, 45 V/μs slew rate, and 17 nV/√Hz maximum input voltage noise, operating across −55°C to +125°C with ±19 V supply rails. It serves as a direct upgrade to TL07x/TL08x amplifiers in precision analog signal conditioning for radar front-ends and avionics sensor interfaces.
For engineers reviewing the 5962-9460203QCA datasheet, 5962-9460203QCA pinout, 5962-9460203QCA application, or 5962-9460203QCA equivalent, this page provides verified package mapping (Ceramic Flatpack U), absolute maximum ratings, offset-trimmed DC performance, noise floor validation, and military-qualified thermal and reliability data per MIL-PRF-38535.
Technical Context
The 5962-9460203QCA implements Texas Instruments' Excalibur BiFET process, combining JFET input stage for >10¹² Ω input resistance with bipolar output drive for ±80 mA output current. Its on-chip zener trimming ensures ≤2 mV input offset voltage at 25°C and ≤4 mV over full temperature range.
It is fully specified at ±5 V and ±15 V supplies, supports common-mode input ranges up to ±10.9 V (at ±15 V), and maintains ≥89 dB CMRR and ≥99 dB SVR - critical for high-dynamic-range instrumentation in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 10 MHz - enables stable closed-loop operation up to 100 kHz with gain ≥100 without phase margin degradation. |
| Slew Rate | 45 V/μs - supports fast transient response in pulse amplification and active filter stages without slew-induced distortion. |
| Input Voltage Noise | 17 nV/√Hz (max) - ensures minimal added noise in low-level sensor signal chains (e.g., piezoelectric accelerometers). |
| Supply Voltage Range | ±2.25 V to ±19 V - accommodates wide dynamic signal swing in ±15 V industrial systems and ±5 V portable avionics. |
| Input Offset Voltage | ≤2 mV (25°C), ≤4 mV (−55°C to +125°C) - reduces DC error in precision integrators and transimpedance amplifiers. |
| Operating Temperature | −55°C to +125°C - qualified per MIL-PRF-38535 Class Q for use in missile guidance, flight control, and space-qualified payloads. |
| Common-Mode Input Range | −10.9 V to +15 V (at ±15 V supply) - allows rail-to-rail input handling in single-supply referenced differential sensing topologies. |
Pinout & Package
Ceramic Flatpack (U) package, 10-pin, hermetically sealed, lead finish SnPb per MIL-STD-1835. Pin 1 marked by notch or dot; pins numbered counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left unconnected or tied to ground only if required by PCB layout EMI mitigation. |
| 2 | OFFSET N1 | Offset null adjustment terminal - used with external potentiometer (10 kΩ) between Pins 1 and 5 to trim input offset voltage. |
| 3 | IN− | Inverting input - high-impedance JFET node; requires guarded trace routing to minimize leakage and capacitive coupling. |
| 4 | IN+ | Non-inverting input - matched to IN− for optimal CMRR; bias current <100 pA enables ultra-high-Z source interfacing. |
| 5 | VCC− | Negative supply rail - must be decoupled with ≥0.1 μF ceramic capacitor placed within 5 mm of pin. |
| 6 | NC | No internal connection - electrically isolated; may be used as mechanical anchor or ground plane via. |
| 7 | VCC+ | Positive supply rail - requires independent 0.1 μF ceramic + 10 μF tantalum decoupling for transient load stability. |
| 8 | OUT | Amplifier output - capable of ±80 mA short-circuit current; drives 600 Ω loads with <0.1% THD+N at 1 kHz. |
| 9 | OFFSET N2 | Second offset null terminal - completes trimming circuit with Pin 2; unused in single-op-amp configurations. |
| 10 | NC | No internal connection - no electrical function; maintain clearance from adjacent traces per MIL-STD-275. |
Key Features
| Feature | Design Value |
|---|---|
| Excalibur BiFET Process | Enables simultaneous 10¹² Ω input resistance and ±80 mA output drive - ideal for interfacing high-Z sensors while driving reactive loads. |
| Zener-Trimmed Input Offset | Guarantees ≤4 mV max offset over −55°C to +125°C - eliminates need for external auto-zero circuitry in precision DC-coupled systems. |
| 17 nV/√Hz Max Input Noise | Ensures SNR preservation in low-amplitude signal paths (e.g., seismic geophone preamps), outperforming TL07x by 3×. |
| ±19 V Supply Capability | Supports full-swing operation in legacy ±15 V military systems with headroom for transient surges - no external clamping required. |
| MIL-PRF-38535 Class Q Qualification | Includes burn-in, temperature cycling, and lot acceptance testing - guarantees reliability in mission-critical aerospace and defense platforms. |

The 5962-9460203QCA features on-chip zener trimming that ensures ≤2 mV input offset voltage at 25°C and ≤4 mV over −55°C to +125°C, eliminating the need for external nulling in most precision DC applications. Offset null pins (2 and 9) are provided only for systems requiring sub-millivolt residual error after calibration.
Is the 5962-9460203QCA pin-compatible with standard TL07x or TL08x op-amps?
Yes - the 5962-9460203QCA uses the same 10-pin Ceramic Flatpack (U) footprint and pinout as the TL071 and TL081 military variants, enabling drop-in replacement in existing designs to immediately improve bandwidth (2×), slew rate (3×), and noise performance without PCB modification.
What is the guaranteed input voltage noise specification for the 5962-9460203QCA?
The 5962-9460203QCA guarantees a maximum input voltage noise of 17 nV/√Hz at 10 kHz, as explicitly stated in the device description and confirmed in the Electrical Characteristics tables for both ±5 V and ±15 V operation - a key differentiator versus TL07x's 18–25 nV/√Hz typical.
How is the 5962-9460203QCA qualified for military use?
The 5962-9460203QCA is manufactured and tested per MIL-PRF-38535 Class Q requirements, including steady-state life test, temperature cycling, burn-in, and lot acceptance testing. It carries QML certification and is listed on the DSCC Qualified Parts List (QPL) for use in DoD-critical systems.
