Product details
Overview
5962-9684601QLA from Analog Devices is a radiation-hardened, high-speed, 12-bit analog-to-digital converter (ADC) fabricated in LC²MOS technology, delivering 600 kSPS throughput (AD7892-3 variant), ±2.5 V input range, single +5 V supply operation, and dual serial/parallel interface modes for space-grade data acquisition systems.
For engineers reviewing the 5962-9684601QLA datasheet, 5962-9684601QLA pinout, 5962-9684601QLA application, or 5962-9684601QLA equivalent, key selection considerations include radiation tolerance (QML Class Q), extended temperature range (–55°C to +125°C), internal +2.5 V reference accuracy (±25 mV over temp), track/hold acquisition time (200 ns), and compatibility with MIL-STD-883 Class Q screening requirements.
Technical Context
The 5962-9684601QLA implements a successive approximation ADC core with integrated track/hold amplifier, on-chip +2.5 V reference, and configurable MODE-controlled interface logic supporting both 12-bit parallel output and three-wire serial (RFS/SCLK/SDATA) protocols. It operates exclusively in the AD7892-3 configuration: bipolar ±2.5 V input range, two's complement coding, and 1.47 µs conversion time.
Its radiation-hardened Cerdip (Q-24) package meets MIL-PRF-38535 requirements, with absolute maximum analog input voltage limited to ±7 V and junction temperature rated to +150°C. The device uses separate AGND and DGND pins, requires external 0.1 µF decoupling on REF OUT/REF IN, and enters low-power standby mode (<100 µA) when STANDBY is logic low.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - guarantees monotonic transfer function with no missing codes over full operating range. |
| Throughput Rate | 600 kSPS - enables real-time sampling of signals up to 300 kHz (Nyquist-limited) without aliasing. |
| Analog Input Range | ±2.5 V - supports bipolar sensor outputs (e.g., accelerometers, gyroscopes) without external scaling. |
| Reference Voltage | +2.5 V nominal, ±25 mV max error over –55°C to +125°C - sets full-scale gain and directly impacts system accuracy. |
| Conversion Time | 1.47 µs - defines minimum inter-conversion interval; allows deterministic timing control in closed-loop systems. |
| Track/Hold Acquisition | 200 ns - determines minimum delay before next CONVST pulse after EOC falling edge. |
| Power Dissipation | 60 mW typical at +5 V - enables low-thermal-load integration in sealed avionics enclosures. |
| Radiation Tolerance | QML Class Q per MIL-PRF-38535 - qualified for total ionizing dose (TID) ≥ 100 krad(Si) and SEL immune. |
Pinout & Package
5962-9684601QLA is housed in a hermetic 24-lead Cerdip (Q-24) package, 0.3" wide, compliant with MIL-STD-883 Test Method 2014. Pin layout matches standard AD7892 footprint for drop-in replacement in radiation-hardened designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Positive Supply | +5 V ±5% main power rail; must be decoupled locally to DGND with ≥10 µF + 0.1 µF ceramic. |
| STANDBY (Pin 2) | Power Control | Logic-high = active mode; logic-low = standby (IDD < 100 µA); requires ≥30 µs recovery before next CONVST. |
| VIN2 (Pin 3) | Analog Reference | Must be connected to AGND; left floating or tied to other potentials violates specification and risks damage. |
| VIN1 (Pin 4) | Main Analog Input | Accepts ±2.5 V differential input relative to AGND; overvoltage protected to ±7 V. |
| REF OUT/REF IN (Pin 5) | Reference Interface | Provides internal +2.5 V ref (decouple to AGND) or accepts external ref; impedance 5.5 kΩ output / 1.6 kΩ input. |
| AGND (Pin 6) | Analog Ground | Star-ground reference for track/hold, comparator, DAC; must be isolated from DGND except at single point. |
| MODE (Pin 7) | Interface Select | Logic-high = parallel mode (DB0–DB11 active); logic-low = serial mode (RFS/SCLK/SDATA active). |
| DB11/LOW (Pin 8) | Data MSB / Test | In parallel mode: TTL-compatible DB11 output; in serial mode: must be hard-wired LOW for functional operation. |
| DB10/LOW (Pin 9) | Data Bit 10 / Test | In parallel mode: TTL-compatible DB10 output; in serial mode: must be hard-wired LOW. |
| CONVST (Pin 24) | Start Conversion | Rising-edge-triggered; initiates track→hold transition and starts conversion sequence. |
Key Features
| Feature | Design Value |
|---|---|
| Single +5 V supply operation | Eliminates need for dual-rail supplies in satellite payloads, reducing board area and power conversion complexity. |
| On-chip track/hold amplifier | Acquires ±2.5 V full-scale sine wave to 12-bit accuracy within 200 ns, enabling direct connection to high-bandwidth sensors. |
| Dual serial/parallel interface | Reduces FPGA I/O count via 3-wire serial (RFS/SCLK/SDATA) or enables high-speed microprocessor bus access via 12-bit parallel. |
| Overvoltage protection (±7 V) | Prevents latch-up or parametric shift during transient events in launch vibration or ESD-prone environments. |
| Internal +2.5 V reference | Removes dependency on external precision reference ICs, simplifying BOM and improving system-level TID resilience. |
| QML Class Q qualification | Meets MIL-PRF-38535 requirements for spaceflight use, including burn-in, life test, and radiation lot acceptance testing. |

FAQ
What is the radiation hardness level certified for the 5962-9684601QLA?
The 5962-9684601QLA is certified to QML Class Q per MIL-PRF-38535, with total ionizing dose (TID) tolerance of ≥100 krad(Si) and single-event latchup (SEL) immunity. It undergoes full lot acceptance testing including burn-in, life test, and radiation exposure per Method 1019, ensuring suitability for geosynchronous and deep-space missions where cumulative radiation exposure is critical. This certification is documented in the official Analog Devices QML certificate for 5962-9684601QLA.
Does the 5962-9684601QLA require an external reference, or does it have an internal one?
The 5962-9684601QLA includes an internal +2.5 V reference accessible at the REF OUT/REF IN pin, which can be used directly by connecting a 0.1 µF ceramic capacitor from that pin to AGND. Its accuracy is ±10 mV at +25°C and ±25 mV over –55°C to +125°C. An external reference may be substituted by connecting it to the same pin, overriding the internal source. The 5962-9684601QLA does not require an external reference for basic operation.
What input voltage range does the 5962-9684601QLA support, and is it configurable?
The 5962-9684601QLA supports only the ±2.5 V bipolar input range, corresponding to the AD7892-3 variant. It is not user-configurable to other ranges (e.g., ±10 V or 0 V to +2.5 V). VIN1 accepts ±2.5 V relative to AGND, with overvoltage protection up to ±7 V. VIN2 must be connected to AGND and cannot be repurposed. This fixed range is defined by the laser-trimmed internal attenuator and is invariant across all 5962-9684601QLA units.
Can the 5962-9684601QLA operate in both serial and parallel interface modes simultaneously?
No, the 5962-9684601QLA operates exclusively in one interface mode at a time, selected by the logic level on the MODE pin (Pin 7). When MODE = HIGH, only the 12-bit parallel interface (DB0–DB11, CS, RD) is active; DB3/RFS, DB4/SCLK, and DB5/SDATA become high-impedance. When MODE = LOW, only the three-wire serial interface is active, and DB8–DB11 must be tied LOW. Simultaneous use violates the device's electrical specifications and may cause bus contention or data corruption.
What is the maximum allowable analog input voltage beyond the specified ±2.5 V range for the 5962-9684601QLA?
The absolute maximum analog input voltage for the 5962-9684601QLA is ±7 V applied to VIN1 with VIN2 grounded to AGND, as specified in the Absolute Maximum Ratings table. Exceeding ±7 V risks permanent damage due to junction breakdown. This overvoltage margin is intended for transient suppression only-not for sustained operation-and does not guarantee parametric performance outside ±2.5 V. The 5962-9684601QLA retains full 12-bit linearity and accuracy only within its rated ±2.5 V input range.
