Product details
Overview
5962-9474301MXA from Analog Devices is a 16-bit, 100 kSPS successive-approximation analog-to-digital converter (ADC) with on-chip sample-hold, autocalibration, and parallel output. It delivers ±1 LSB INL (J/A grade), –97 dB THD, 90 dB S/(N+D), 1 MHz full-power bandwidth, and operates from +5 V, ±12 V supplies. It is used in precision instrumentation, automated test equipment, and high-fidelity data acquisition systems requiring stable dc accuracy and dynamic performance.
For engineers reviewing the 5962-9474301MXA datasheet, 5962-9474301MXA pinout, 5962-9474301MXA application, or 5962-9474301MXA equivalent, key selection considerations include its MIL-STD-883–screened ceramic DIP package, dual-chip BiMOS II/DSP CMOS architecture, 10 µs conversion time, twos-complement output coding, and requirement for external 5–10 V reference voltage.
Technical Context
The 5962-9474301MXA implements a switched-capacitor charge-redistribution SAR architecture-eliminating laser-trimmed resistor ladders-and integrates two monolithic dies: an analog ADC chip (BiMOS II) and a digital controller chip (DSP CMOS). Its autocalibration uses an on-chip microcontroller and calibration DAC to measure and store capacitor mismatch corrections in RAM for real-time error compensation.
Conversion is initiated by the falling edge of SAMPLE, followed by 17 CLK cycles; BUSY asserts high during conversion and calibration. The device supports continuous conversion mode, requires separate AGND/DGND planes with single-point interconnection, and mandates strict decoupling: 0.1 µF capacitors placed adjacent to each supply pin (VCC, VEE, VDD) and VREF.
Key Specifications

Pinout & Package
5962-9474301MXA is housed in a 28-pin side-brazed ceramic DIP (package option D-28), compliant with MIL-STD-883 screening requirements for military and aerospace applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–6 | BIT 11–BIT 16 (DO) | LSB data outputs (parallel, twos-complement format); require termination and controlled impedance routing |
| 7 | BUSY (DO) | Active-high status flag indicating conversion or calibration in progress; must be buffered if loaded >1 TTL input |
| 8 | CAL (DI) | Asynchronous hardware reset and calibration trigger; initiates 85,530-clock autocalibration sequence |
| 9 | SAMPLE (DI) | Acquisition control; HIGH enables track mode, falling edge initiates conversion or holds LOW during calibration |
| 10 | CLK (DI) | Master clock input; rising edge drives SAR logic; minimum 480 ns period required for valid timing |
| 11 | DGND (P) | Digital ground reference; must be isolated from AGND except at single-point connection near AD676 |
| 12 | VCC (P) | +12 V analog supply for SHA and ADC core; requires dedicated 0.1 µF bypass to AGND |
| 13 | AGND (P/AI) | Analog ground return; primary reference for VIN, VREF, and internal analog circuitry |
| 14 | AGND SENSE (AI) | High-impedance analog ground sense node; connects to system AGND to compensate for trace IR drop |
| 15 | VIN (AI) | Differential analog input (±VREF range); requires low-noise buffer and matched layout to AGND SENSE |
| 16 | VREF (AI) | External reference voltage input (5–10 V); dictates full-scale range and directly impacts gain error and noise floor |
| 17 | VEE (P) | –12 V analog supply; ceramic package lid is internally tied to VEE - ensure mechanical grounding compliance |
| 18 | VDD (P) | +5 V digital supply for logic outputs and controller; bypassed separately to DGND with 0.1 µF |
| 19–28 | BIT 1–BIT 10 (DO) | MSB data outputs (parallel, twos-complement); BIT 1 = MSB, BIT 10 = MSB-9; routed away from clock/noise sources |

FAQ
What is the operating temperature range for the 5962-9474301MXA?
The 5962-9474301MXA is rated for –40°C to +85°C operation and is screened per MIL-STD-883 for extended environmental reliability. This range is validated across all dc and ac specifications including INL, THD, and S/(N+D), with temperature drift coefficients specified for zero and gain error. The 5962-9474301MXA maintains ±1.5 LSB INL and –92 dB THD across this full range, making it suitable for harsh deployment environments where commercial-grade ADCs would degrade.
Does the 5962-9474301MXA require an external voltage reference?
Yes, the 5962-9474301MXA requires an external precision voltage reference applied to the VREF pin, with a supported range of 5 V to 10 V. Reference choice directly determines full-scale input range (±VREF) and impacts gain error, noise floor, and S/(N+D) performance. The 5962-9474301MXA does not include an internal reference; using a low-drift, low-noise reference such as the REF102 or ADR44x series is recommended to achieve datasheet-specified accuracy.
How does autocalibration work in the 5962-9474301MXA?
The 5962-9474301MXA performs autocalibration by measuring capacitor mismatches in its internal charge-redistribution array using an on-chip microcontroller and calibration DAC. Offset and gain errors are captured, stored in on-chip RAM, and applied during subsequent conversions. Calibration is triggered asynchronously via the CAL pin and completes in 85,530 clock cycles. The 5962-9474301MXA achieves full 16-bit linearity only after calibration - uncalibrated operation may fall to ~10-bit effective resolution.
Can the 5962-9474301MXA operate in continuous conversion mode?
Yes, the 5962-9474301MXA supports continuous conversion mode by reasserting SAMPLE while BUSY is still HIGH, enabling overlapping acquisition and conversion. This maximizes throughput to 100 kSPS. Timing must strictly adhere to tSC (SAMPLE LOW to first CLK delay) and tSL (minimum SAMPLE LOW duration) to avoid corruption. The 5962-9474301MXA's BUSY signal remains valid for latching previous data even during the next acquisition phase.
What are the power supply requirements for the 5962-9474301MXA?
The 5962-9474301MXA requires three independent supplies: +5 V (VDD) for digital logic, +12 V (VCC) and –12 V (VEE) for analog circuitry. Supplies must be regulated to ±5% (VCC/VEE) and ±10% (VDD), with <1% ripple. Each supply pin demands local 0.1 µF ceramic bypassing to its respective ground plane (DGND for VDD, AGND for VCC/VEE/VREF). Failure to isolate analog and digital grounds or omit bypassing degrades THD and S/(N+D) by >10 dB.
