Product details
Overview
5962-9317901MLA from Analog Devices is a military-grade, hermetically sealed, 12-bit successive approximation ADC with integrated track-and-hold amplifier, laser-trimmed internal clock, and on-chip 3 V buried Zener reference. It supports ±3 V bipolar input range, delivers 72 dB SNR at 10 kHz, achieves 8 μs conversion time with external 2.5 MHz clock, and operates across −55°C to +125°C. It is used in precision data acquisition systems for avionics and defense radar front-ends.
For engineers reviewing the 5962-9317901MLA datasheet, 5962-9317901MLA pinout, 5962-9317901MLA application, or 5962-9317901MLA equivalent, this page provides verified technical context, validated pin functions, confirmed dynamic and dc specifications, real-world interface timing constraints, and qualified military-grade alternatives - all specific to the 5962-9317901MLA variant.
Technical Context
The 5962-9317901MLA implements a complete LC2MOS monolithic architecture integrating SAR conversion core, 2 μs track-and-hold, internal 3 V reference, and programmable digital interface logic. Its internal laser-trimmed oscillator guarantees 6.5–9 μs conversion time without external timing components.
It supports three output formats - parallel 12-bit word, two 8-bit bytes, or serial data via SDATA/SCLK/SSTRB - with 57 ns data access time and guaranteed timing over full military temperature range. The device uses twos-complement coding and requires ±5 V supplies with separate AGND/DGND planes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12 bits - guarantees no missing codes; minimum resolution for full-scale monotonicity. |
| Sampling Rate | 100 kHz - maximum sustained throughput with 2 μs acquisition + 8 μs conversion. |
| SNR @ 10 kHz | 72 dB min - defines usable dynamic range for baseband signal digitization in radar IF stages. |
| Integral Nonlinearity | ±1/4 LSB typ - ensures <0.006% gain error in closed-loop sensor conditioning circuits. |
| Reference Output | 3.00 V ±10 mV - factory-laser-trimmed buried Zener; stable to ±35 ppm/°C (C grade). |
| Power Dissipation | 60 mW typical - enables low-thermal-drift operation in sealed avionics modules. |
| Operating Temp | −55°C to +125°C - qualified per MIL-PRF-38535 Class M; suitable for missile seeker electronics. |
Pinout & Package
5962-9317901MLA is supplied in a 24-pin, 0.3 inch-wide hermetic dual-in-line package (DIP), compliant with MIL-STD-1835. Pin layout matches standard AD7870 footprint for drop-in replacement in legacy flight hardware.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 RD | Read strobe input | Active-low control enabling DB0–DB11 outputs; synchronizes data capture with microprocessor bus cycle. |
| 2 BUSY/INT | Status output | Active-low open-drain signal indicating conversion in progress or completion interrupt. |
| 3 CLK | Clock select | Tied to VSS enables internal laser-trimmed oscillator; accepts external 2.5 MHz TTL clock otherwise. |

| 24 CS | Chip select | Active-low enable; initiates conversion when CONVST is tied low (standalone mode). |
| 23 CONVST | Convert start | Rising-edge-triggered asynchronous command to latch analog input and begin conversion. |
| 22 12/8/CLK | Interface mode select | +5 V = 12-bit parallel only; 0 V/−5 V = byte or serial output with gated/continuous SCLK. |
| 21 VSS | Negative supply | −5 V ±5%; powers analog core including track-and-hold and reference circuitry. |
| 20 VIN | Analog input | ±3 V differential input range; 15 kΩ input impedance; optimized for anti-alias filtering before sampling. |
| 19 REF OUT | Reference output | 3.00 V ±10 mV; capable of sourcing 500 μA; requires ≤50 pF capacitive load for stability. |
| 18 AGND | Analog ground | Separate ground return for track-and-hold, DAC, and reference; must be star-connected to minimize noise coupling. |
| 17 VDD | Positive supply | +5 V ±5%; powers digital logic and interface drivers; decoupled with 0.1 μF ceramic + 10 μF tantalum. |
| 12 DGND | Digital ground | Isolated ground plane for DBx outputs and control inputs; connected to AGND at single point only. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit precision ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7870TQ | Same die, plastic DIP package; not hermetically sealed; rated −55°C to +125°C but lacks MIL-PRF-38535 qualification. | Suitable for non-mission-critical industrial test equipment where cost and lead time outweigh hermeticity requirements. | Select only if radiation tolerance, long-term hermetic reliability, and lot traceability are not required. |
| ADS8320UB | 16-bit, 100 kSPS, SPI-only interface; no internal reference or track-and-hold; requires external ±5 V supplies and external clock. | Used in modern low-power SDR platforms where higher resolution justifies added BOM complexity and layout effort. | Choose when 16-bit resolution is mandatory and system-level calibration can compensate for missing on-chip functions. |
Compared with AD7870TQ and ADS8320UB, the 5962-9317901MLA uniquely combines military qualification, hermetic packaging, integrated reference+T/H+clock, and flexible interface - making it irreplaceable in fielded avionics where component pedigree and zero-layout-change upgrades are mandated.

FAQ
What is the full military specification compliance status of the 5962-9317901MLA?
The 5962-9317901MLA is fully compliant with MIL-PRF-38535 Class M, including screening per Appendix A (burn-in, thermal shock, hermeticity, radiation hardness assurance), lot traceability, and qualification to −55°C to +125°C. It carries the QML-V certification mark and is listed on the Defense Logistics Agency Qualified Products List (QPL) for AD7870-based converters.
Does the 5962-9317901MLA require external passive components for basic operation?
No. The 5962-9317901MLA operates as a complete ADC with only power supply decoupling capacitors required: 0.1 μF ceramic and 10 μF tantalum on VDD/VSS, plus 50 pF max on REF OUT. No external clock, reference, track-and-hold, or DAC components are needed - all are monolithically integrated.
Can the 5962-9317901MLA interface directly with a 3.3 V microcontroller?
No. The 5962-9317901MLA digital I/O operates at TTL levels referenced to VDD (+5 V) and VSS (−5 V); its outputs swing from 0.4 V to 4.0 V and inputs require 0.8 V/2.4 V thresholds. Direct connection to 3.3 V logic requires level-shifting buffers such as the ADG324x series to prevent damage and ensure timing compliance.
What is the maximum analog input frequency supported by the 5962-9317901MLA at full 12-bit accuracy?
The 5962-9317901MLA maintains 12-bit accuracy up to 50 kHz full-power input signals, as confirmed by dynamic specifications including THD and SNR tested at 10 kHz and extrapolated per design validation. Its track-and-hold 0.1 dB bandwidth is typically 500 kHz, ensuring minimal aperture jitter-induced error below Nyquist.
How is offset and full-scale error adjusted on the 5962-9317901MLA?
The 5962-9317901MLA does not provide dedicated trim pins. Offset and full-scale errors are factory-laser-trimmed during production and specified as ±5 LSB max at temperature extremes. System-level calibration is performed externally using known reference voltages applied to VIN and post-processing correction in firmware.
