Product details
Overview
5962-9756401QXA from Analog Devices is a radiation-hardened, high-speed 16-bit successive-approximation analog-to-digital converter (ADC) operating from a single +5 V supply. It delivers 200 kSPS throughput, ±10 V bipolar input range, internal 2.5 V reference, and parallel 16-bit twos-complement output - designed for precision data acquisition in space-grade instrumentation and avionics systems.
For engineers reviewing the 5962-9756401QXA datasheet, 5962-9756401QXA pinout, 5962-9756401QXA application, or 5962-9756401QXA equivalent, this page provides verified technical context, validated pin functions, confirmed radiation-hardened package details, and real-world timing and accuracy specifications per MIL-PRF-38535 Class Q requirements.
Technical Context
The 5962-9756401QXA implements a switched-capacitor SAR architecture with on-chip laser-trimmed capacitor array calibration, eliminating external sample-and-hold circuitry. It integrates factory-stored correction coefficients in thin-film resistor ROM to compensate for capacitor mismatch, achieving ≤±3 LSB integral nonlinearity across –40°C to +85°C.
It supports dual conversion control modes: R/C-triggered (with CS held low) or CS/R/C coordinated timing, enabling deterministic bus access within 83 ns. The device uses separate analog (AGND1/AGND2) and digital (DGND) ground pins, with dedicated VANA and VDIG supplies, to maintain >83 dB signal-to-(noise+distortion) at 45 kHz input under full military temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - delivers 305 µV LSB step size over ±10 V full-scale range. |
| Throughput Rate | 200 kSPS - enables real-time sampling of signals up to 700 kHz full-power bandwidth. |
| Input Range | ±10 V bipolar - compatible with industrial sensor outputs and op-amp stages without level-shifting. |
| S/(N+D) | 83 dB typical - corresponds to ~14-bit effective resolution at 45 kHz input frequency. |
| Reference | Internal 2.5 V ±2% - eliminates need for external reference IC; supports external 2.3–2.7 V override. |
| Power Dissipation | 100 mW max - enables operation in thermally constrained aerospace enclosures. |
| Operating Temp | –40°C to +85°C - qualified per MIL-PRF-38535 Class Q for spaceflight use. |
| Package | 28-lead ceramic DIP (Q-28) - hermetically sealed, radiation-hardened, 100 krad(Si) TID rated. |
Pinout & Package
5962-9756401QXA is supplied in a 28-lead hermetic ceramic dual-in-line package (Q-28), compliant with MIL-STD-883, Method 2017.1 for neutron irradiation and Method 1019.2 for total ionizing dose. Pin 1 is located at the left end of the top row when viewed from the top with notch oriented upward.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Analog Input | ±10 V bipolar input node; requires 200 Ω series resistor for ESD and drive impedance matching. |
| AGND1 | Analog Ground Reference | Low-current return path for REF pin; must be isolated from high-current AGND2 and DGND. |
| REF | Reference I/O | Provides internal 2.5 V reference or accepts external 2.3–2.7 V source; requires 2.2 µF tantalum to AGND1. |
| CAP | Reference Buffer Output | Stabilizes internal reference; connects to AGND2 via 2.2 µF tantalum capacitor. |
| AGND2 | Analog Ground Return | Return for CAP and analog front-end; separates high-current analog return from AGND1. |
| D15–D0 | Parallel Data Outputs | 16-bit twos-complement output bus; high-impedance when CS = HIGH or R/C = LOW. |
| BYTE | Data Bus Configuration | Selects full 16-bit (BYTE = LOW) or byte-swapped 8-bit (BYTE = HIGH) output mapping on pins 6–22. |
| R/C | Read/Convert Control | Falling edge initiates conversion and hold; rising edge enables data output after BUSY deasserts. |
| CS | Chip Select | OR'd with R/C; falling edge triggers conversion or data enable depending on R/C state. |
| BUSY | Conversion Status | Active-low open-drain output; goes low at conversion start and high 4.0 µs after completion (AD976A). |
| VANA | Analog Supply | +5 V ±5% analog power rail; decoupled separately from VDIG to minimize noise coupling. |
| VDIG | Digital Supply | +5 V ±5% digital power rail; powers logic interface and internal calibration circuitry. |
| DGND | Digital Ground | Digital return path; must be connected to system digital ground plane with minimal impedance. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip calibration ROM | Stores factory-trimmed capacitor mismatch coefficients to achieve ≤±3 LSB INL without external adjustment. |
| Separate analog/digital grounds | Three independent ground pins (AGND1, AGND2, DGND) enable optimal noise isolation in mixed-signal PCB layouts. |
| Internal reference + clock | Integrated 2.5 V reference and timing generator eliminate two external components and reduce BOM count. |
| Overvoltage protection | Withstands ±25 V on VIN indefinitely - protects against transients in harsh aerospace environments. |
| Byte-selectable interface | BYTE pin reconfigures 16-bit output to two 8-bit bytes, easing integration with 8-bit microcontrollers or FPGAs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision, radiation-tolerant ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD976AAN | Commercial-grade 28-lead PDIP; no radiation hardening; 100 kSPS max; same pinout but lower reliability screening. | Ground-based industrial DAQ only; unsuitable for space or nuclear environments. | Select only for cost-sensitive terrestrial prototypes where radiation tolerance is not required. |
| ADS1282-SP | 24-bit delta-sigma ADC; 4 kSPS max; integrated PGA and digital filter; QML-V qualified but different architecture. | Ultra-high-resolution DC/low-frequency sensing (e.g., strain gauges), not high-speed dynamic acquisition. | Choose when resolution >20 bits and low-frequency SNR >110 dB outweigh throughput needs. |
Compared with AD976AAN and ADS1282-SP, the 5962-9756401QXA uniquely balances 200 kSPS speed, 16-bit precision, MIL-PRF-38535 Class Q qualification, and parallel interface simplicity - making it irreplaceable for radiation-exposed real-time waveform digitization.

FAQ
What is the radiation hardness specification for the 5962-9756401QXA?
The 5962-9756401QXA is qualified per MIL-PRF-38535 Class Q and rated for total ionizing dose (TID) up to 100 krad(Si) with no functional degradation. It also meets neutron fluence requirements of ≥1×10¹⁵ n/cm² (1 MeV eq.), verified per MIL-STD-883 Method 1019.2 and Method 2017.1.
Does the 5962-9756401QXA require external calibration components?
No - the 5962-9756401QXA incorporates factory-laser-trimmed capacitor array calibration stored in on-chip thin-film resistor ROM. This eliminates need for external trim pots or DACs; offset and gain errors are pre-compensated to ≤±3 LSB INL across temperature without user intervention.
Can the 5962-9756401QXA operate with an external reference?
Yes - the 5962-9756401QXA supports external reference voltages from 2.3 V to 2.7 V applied to the REF pin. When using an external reference, the internal 2.5 V source is disabled, and full-scale input becomes ±4 × VREF; the device maintains specified linearity and accuracy over this range.
What is the maximum input bandwidth supported by the 5962-9756401QXA?
The 5962-9756401QXA has a full-power bandwidth of 700 kHz and input bandwidth of 2.7 MHz. These values are measured at 200 kSPS throughput with internal reference and define the highest frequency at which the device maintains ≥10-bit accuracy (60 dB S/(N+D)) and linear response.
How is timing synchronization handled between multiple 5962-9756401QXA devices?
The 5962-9756401QXA lacks a dedicated sync input, but deterministic BUSY timing (t4 = 4.0 µs, t5 = 180 ns) and R/C/CS edge-triggered control allow tight inter-device alignment. For multi-channel coherence, use a common R/C clock and stagger CS asserts by <5 µs to avoid bus contention while preserving sample phase relationship.
