Product details
Overview
5962-89616042A from Analog Devices, Inc. is a MIL-PRF-38535 Class B qualified, CMOS 8-bit analog-to-digital converter designed for microprocessor-compatible static RAM interface operation. It features ±10 V reference input, 15 μs conversion time, 1.5% resistance mismatch (BOFS to AAIN), and operates across –55°C to +125°C. Used in military avionics data acquisition systems requiring high-reliability unipolar ADC performance.
For engineers reviewing the 5962-89616042A datasheet, 5962-89616042A pinout, 5962-89616042A application, or 5962-89616042A equivalent, this page delivers verified electrical specs, truth table behavior, timing constraints for static RAM mode, and direct alternative part comparisons with documented functional and interface differences.
Technical Context
The 5962-89616042A implements a successive-approximation architecture with internal track-and-hold, supporting unipolar input ranges up to 20 V via external VREF and BOFS biasing. It uses asynchronous control logic with CS and RD strobes and outputs 8-bit parallel data on DB0–DB7 pins in high-impedance or driven states.
Timing is governed by an external 550 kHz clock (RCLK = 150 kΩ), enabling guaranteed 15 μs conversion time and BUSY-driven handshaking. Truth table behavior differs from device types 01/02: CS must be low to initiate conversion, and RD high-to-low transitions are prohibited during BUSY assertion to avoid undefined states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit unipolar output with LSB = VREF/256; supports 0–20 V input range when VREF = –10 V |
| Conversion Time | 15 μs maximum - enables ≥66.7 kSPS sustained sampling in static RAM interface mode |
| Integral Nonlinearity | ±0.75 LSB - ensures monotonicity and <0.3% full-scale error over –55°C to +125°C |
| Supply Voltage | +5 V DC only - requires separate AGND/DGND grounds with ≤0.3 V offset for specified accuracy |
| Input Resistance | 10–30 kΩ at AIN, BOFS, and VREF pins - defines minimum external source impedance for gain/offset error control |
| Operating Temperature | –55°C to +125°C - qualified per MIL-STD-883 Group A subgroups 1–3 for extended environmental robustness |
| Digital Interface | Static RAM mode only - no ROM or slow-memory mode support; CS/RD timing defined per Figure 2 and Table I |
Pinout & Package
5962-89616042A is supplied in GDIP1-T18 (18-pin ceramic dual-in-line) package per MIL-STD-1835 outline V, hermetically sealed and lead-finished per MIL-PRF-38535 Appendix A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | +5 V power supply; decoupling capacitor required within 1 cm of pin to suppress switching noise |
| 2 | VREF | Reference voltage input; accepts –10 V for 0–20 V unipolar input range; high-impedance node |
| 3 | BOFS | Bias offset input; sets zero-scale point; matched to AAIN with ≤1.5% resistance mismatch |
| 4 | AIN | Analog input; unipolar range determined by VREF and BOFS; 10–30 kΩ input resistance |
| 5 | AGND | Analog ground return; must be isolated from DGND except at single-point star connection |
| 6–13 | DB7–DB0 | 8-bit parallel digital output bus; tri-state capable; VOL ≤ 0.4 V @ 1.6 mA sink |
| 14 | BUSY | Open-drain status flag; active high during conversion; requires external pull-up for TTL compatibility |
| 15 | RD | Read strobe input; falling edge latches converted data onto DB7–DB0; must remain high during BUSY |
| 16 | CS | Chip select input; falling edge initiates conversion; must be low before RD assertion |
| 17 | CLK | External clock input; 550 kHz nominal; RCLK = 150 kΩ required for timing compliance |
| 18 | DGND | Digital ground return; separated from AGND to minimize digital switching noise coupling into analog path |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8961604VA | Same device type (04), but case outline 2 (CQCC1-N20, 20-pin CLCC); no GDIP1-T18 pinout compatibility | Requires PCB redesign due to square leadless package and 20-pin layout; not drop-in | Select only when CLCC packaging and surface-mount assembly are mandatory for size or ruggedization requirements. |
| MX7574SE/883B | Maxim variant with identical electrical specs and timing; same device type 04, outline V, but different vendor CAGE (1ES66) | Functionally identical interface and performance; qualified to same MIL-PRF-38535 Class B requirements | Preferred for dual-sourcing; shares identical pinout, truth table, and timing - true second-source option. |
Compared with 5962-89616042A, 5962-8961604VA demands board-level redesign due to CLCC packaging and extra pins, while MX7574SE/883B offers identical GDIP1-T18 form-fit-function with full documentation traceability to DSCC Bulletin 01-07-16.

FAQ
What is the maximum clock frequency supported by the 5962-89616042A?
The 5962-89616042A is specified for use with a 550 kHz external clock, implemented via a 150 kΩ pull-up resistor on the CLK pin. This frequency yields a guaranteed 15 μs conversion time. Operating above this frequency violates timing parameters in Table I and may cause BUSY assertion failures or data corruption. The 5962-89616042A does not support programmable or internal clock generation.
Does the 5962-89616042A support bipolar input configurations?
No, the 5962-89616042A is specified exclusively for unipolar operation per the drawing's "Unipolar configuration unless otherwise specified" clause in Table I. Its truth tables, timing waveforms, and absolute maximum ratings (e.g., VAIN = 20 V dc) assume 0–VREF input ranges. Bipolar operation is not characterized, tested, or guaranteed for the 5962-89616042A.
Can the 5962-89616042A be used in ROM mode or slow-memory mode?
No. The 5962-89616042A (device type 04) only supports static RAM interface mode, as confirmed by its dedicated truth table on Sheet 10 and absence of ROM/slow-memory timing parameters in Table I. Attempting ROM or slow-memory protocols will result in undefined BUSY behavior and invalid DB7–DB0 output states.
What is the meaning of the "C" marking on the 5962-89616042A package?
The "C" marking on the 5962-89616042A indicates compliance with MIL-PRF-38535 Appendix A for non-JAN Class B devices, as required by Section 3.5.1. It certifies that the unit meets all screening, test, and documentation requirements in the drawing - including Group A subgroups 1–3, burn-in per Method 1015, and conformance to Table I limits across –55°C to +125°C.
Is the 5962-89616042A pin-compatible with earlier revisions like 5962-8961601VA?
No. While all device types (01–04) share the same GDIP1-T18 outline V pin numbering per Figure 1, the 5962-89616042A (type 04) has distinct timing (e.g., tC = 15 μs vs. 6 μs for type 01), truth table logic (CS polarity and RD interaction), and clock resistor value (150 kΩ vs. 43 kΩ). Interchanging them without firmware and timing validation risks data loss or BUSY lockup.
