Product details
Overview
5962-8961603VA from Analog Devices, Inc. is a MIL-PRF-38535 Class B qualified, hermetically sealed CMOS 8-bit analog-to-digital converter with dual-in-line (GDIP1-T18) packaging, ±10 V reference input capability, 15 μs conversion time, and microprocessor-compatible parallel interface for unipolar operation in harsh-environment data acquisition systems.
For engineers reviewing the 5962-8961603VA datasheet, 5962-8961603VA pinout, 5962-8961603VA application, or 5962-8961603VA equivalent, key selection criteria include its -55°C to +125°C operating range, static RAM interface timing compatibility, 0.75 LSB differential nonlinearity, 1.5% resistance mismatch between BOFS and AAIN, and compliance with MIL-STD-883 Group A/B/C/D test requirements.
Technical Context
The 5962-8961603VA implements a successive-approximation ADC architecture with internal track-and-hold, supporting three interface modes: static RAM, slow-memory, and ROM. It uses an external 550 kHz clock (RCLK = 150 kΩ), requires separate analog and digital ground connections (AGND/DGND), and features independent VREF (–10 V), BOFS (20 V), and AIN (20 V) voltage rails.
Its functional behavior is defined by truth tables specifying CS/RD-controlled start, read, and reset operations, with BUSY signal assertion during conversion and automatic internal reset on RD low-to-high transitions - independent of CS or BUSY state - ensuring deterministic timing recovery in embedded control loops.
Key Specifications

Pinout & Package
5962-8961603VA is housed in a hermetically sealed GDIP1-T18 (18-pin ceramic dual-in-line) package per MIL-STD-1835, with 0.3-inch row spacing and through-hole mounting. Pin 1 is VDD; pins 11 and 19 are NC; pin 20 is DGND. The package meets MIL-PRF-38535 Class B screening requirements including burn-in and steady-state life testing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 3 | BOFS | Bias offset adjustment terminal (up to +20 V) for input stage trimming |
| 4 | AIN | Analog input (0–10 V unipolar) referenced to AGND |
| 5 | AGND | Analog ground - must be isolated from DGND except at single-point star connection |
| 6–13 | DB7–DB0 | 8-bit parallel data bus - high-impedance when CS high or BUSY active |
| 14 | BUSY | Open-collector status flag - low during conversion, high when data valid |
| 15 | RD | Read strobe - low-to-high transition resets converter regardless of CS state |
| 16 | CS | Chip select - enables interface and initiates conversion on falling edge |
| 17 | CLK | External clock input - 550 kHz required for 15 μs conversion timing |
| 18 | DGND | Digital ground - separate return path for DBx, BUSY, RD, CS, CLK |
| 11, 19 | NC | No connection - must remain unconnected per MIL-STD-1835 outline |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX7574TQ/883B | Same GDIP1-T18 package, identical pinout, but specified for +125°C max (not -55°C min); INL = 1.0 LSB | Qualified for commercial/military hybrid use where extended cold-start performance is not required | Select when full military temperature range is unnecessary and Maxim's QML-38535 sourcing is preferred |
| AD908AX | Same AD-908A core, faster 6 μs conversion, but requires 1.35 MHz clock and has tighter 0.5 LSB INL spec | Optimized for high-throughput systems needing sub-10 μs latency; incompatible clock network and timing margins | Choose only if system clock infrastructure supports 1.35 MHz and timing budget allows tighter setup/hold constraints |
Compared with MX7574TQ/883B and AD908AX, the 5962-8961603VA uniquely balances guaranteed -55°C startup, 15 μs deterministic conversion, and static RAM interface simplicity - making it optimal for legacy-mandated, cold-environment, and resource-constrained embedded control designs.

FAQ
What is the absolute maximum voltage rating for VREF on the 5962-8961603VA?
The absolute maximum voltage rating for VREF on the 5962-8961603VA is –20 V dc. Operation at the recommended –10 V dc ensures full 0–10 V unipolar input range while maintaining specified INL and DNL performance across –55°C to +125°C. Exceeding –20 V risks permanent damage to the internal reference amplifier stage.
Does the 5962-8961603VA support bipolar input configurations?
No, the 5962-8961603VA is specified exclusively for unipolar operation per MIL-STD-883 test conditions and Figure 1 terminal definitions. Its truth tables, timing waveforms, and electrical characteristics (e.g., VREF = –10 V, AIN = 0–10 V) assume single-ended positive input referenced to AGND. Bipolar operation is not characterized or guaranteed.
How does the RD pin function during conversion on the 5962-8961603VA?
On the 5962-8961603VA, a low-to-high transition on the RD pin performs an unconditional internal reset - terminating any ongoing conversion, clearing the output register, and returning the BUSY signal to high impedance. This occurs regardless of CS or BUSY state, enabling robust error recovery in interrupt-driven firmware without polling.
What is the purpose of the BOFS pin on the 5962-8961603VA?
The BOFS (Bias Offset) pin on the 5962-8961603VA provides a trim point for the input stage bias current, allowing compensation of resistor ladder mismatches that affect offset error. It accepts up to +20 V dc and is used with external resistors to adjust VOS to ≤30 mV (min) over temperature - critical for precision DC measurement accuracy.
Is the 5962-8961603VA pin-compatible with the AD908AX or PM-7574B variants?
The 5962-8961603VA shares the same GDIP1-T18 package and pinout with AD908AX (device type 01) and PM-7574B (device type 04), but timing parameters differ significantly: 5962-8961603VA uses 550 kHz clock and 15 μs conversion, whereas AD908AX requires 1.35 MHz and achieves 6 μs. Direct substitution may cause timing violations unless system clock and interface logic are revalidated.
