Product details
Overview
5962-85127023A from Analog Devices is a military-grade 12-bit monolithic analog-to-digital converter with ±1 LSB linearity error over –55°C to +125°C, internal 10 V reference (±0.2%), and dual unipolar/bipolar input ranges (0–10 V, ±5 V, ±10 V). It performs successive-approximation conversion in ≤35 µs and supports 12-bit parallel or byte-mode (8+4) output via CE/CS/R/C/A0 control logic - used in avionics data acquisition, missile guidance signal conditioning, and hardened test instrumentation.
For engineers reviewing the 5962-85127023A datasheet, 5962-85127023A pinout, 5962-85127023A application, or 5962-85127023A equivalent, this page delivers verified specs, MIL-STD-883B qualified package details, real-world timing constraints, and direct alternatives for high-reliability analog interface design.
Technical Context
The 5962-85127023A implements a fully integrated successive-approximation register (SAR) architecture with on-chip 12-bit current-output DAC, comparator, clock generator, and temperature-compensated buried Zener reference. It requires no external precision components for full 12-bit operation.
Its control logic accepts standard microprocessor signals (CE, CS, R/C, A0, 12/8) to initiate 8-bit or 12-bit conversions and enable parallel data readout in either 12-bit word or two 8-bit nibbles - with STS status flag indicating conversion progress and completion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12 bits - delivers 4096 discrete digital codes across full-scale range |
| Linearity Error (TMIN–TMAX) | ±1 LSB - guarantees monotonicity and predictable code transition behavior across –55°C to +125°C |
| Conversion Time | ≤35 µs for 12-bit - enables sampling of signals up to ~26 kHz when paired with AD585 SHA |
| Input Ranges | Unipolar: 0–10 V or 0–20 V; Bipolar: ±5 V or ±10 V - selectable via pin-strapping without external scaling |
| Internal Reference | 10.00 V ±0.2% - stable buried Zener source, supplies 1.5 mA for external buffering |
| Power Supplies | VLOGIC = +4.5–5.5 V; VCC = +11.4–16.5 V; VEE = –11.4––16.5 V - supports ±12 V or ±15 V operation |

Pinout & Package
Ceramic Dual-In-Line Package (D-28), hermetically sealed, compliant with MIL-STD-1835. Pin layout matches standard 28-pin DIP footprint with 0.6-inch body width and 0.3-inch row spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | Digital Common (DC) | Reference ground for logic supply and digital I/O; must be tied to analog common at package for best accuracy |
| 2–13, 16–27 | DB11–DB0 | 12-bit parallel data outputs (3-state); DB11 = MSB, DB0 = LSB - configurable as 12-bit word or 8+4 nibble mode |
| 14 | STS | Status flag: high during conversion, low when result ready - used for handshaking with host processor |
| 28 | REF OUT | 10 V reference output - supplies internal DAC and external circuitry; load must remain constant during conversion |
| 9 | Analog Common (AC) | High-fidelity ground reference for internal reference, input resistors, and comparator - critical for 12-bit accuracy |
| 8, 10 | REF IN | Reference input node - connected internally to REF OUT; external 50 Ω resistor enables full-scale calibration trim |
| 13, 14 | 10VIN / 20VIN | Unipolar analog inputs - 10VIN (5 kΩ input impedance) for 0–10 V; 20VIN (10 kΩ) for 0–20 V range |
| 6 | BIP OFF | Bipolar offset adjustment node - connected to REF OUT for ±5 V/±10 V operation |
| 3, 4, 5, 7 | CE, CS, R/C, A0 | Control inputs - CE/CS enable device; R/C selects convert/read; A0 selects MSB/LSB byte in 8-bit mode |
| 20 | 12/8 | Data format select - tied to VLOGIC for 12-bit word output; tied to DC for 8-bit bus compatibility |
Key Features
| Feature | Design Value |
|---|---|
| On-chip 10 V reference | Eliminates need for external precision voltage reference; ±0.2% initial tolerance supports system-level calibration |
| No missing codes (11-bit) | Guarantees monotonic response over full temperature range - essential for closed-loop control stability |
| Configurable 8-/12-bit conversion | Reduces conversion time to ≤24 µs for 8-bit results - useful for rapid coarse/fine acquisition sequences |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD574ASD | MIL-qualified ceramic DIP variant with identical pinout, specs, and –55°C to +125°C range; differs only in screening documentation and lot traceability | Same avionics/defense use cases; lacks 5962-85127023A's specific QML-V certification level | Select when full QML-V documentation and DSCC source control drawing compliance are not required |
| ADS8688IPWR | 16-bit SAR ADC with integrated programmable gain amplifier (PGA), SPI interface, and ±10.24 V input range; consumes 22 mW vs. 725 mW | Targets modern low-power embedded systems; lacks MIL-qualification, bipolar offset trim, and direct 8-bit bus compatibility | Select for new designs prioritizing resolution and power efficiency over legacy interface compatibility and military screening |
Compared with AD574ASD, 5962-85127023A provides stricter QML-V conformance and extended lifecycle support for defense programs; compared with ADS8688IPWR, it offers proven radiation-tolerant packaging and direct microprocessor bus integration but at higher power and lower resolution.

FAQ
What is the operating temperature range certified for 5962-85127023A?
The 5962-85127023A is screened and certified for continuous operation from –55°C to +125°C per MIL-STD-883B, Class S requirements. This range is validated through thermal cycling, burn-in, and parametric testing at temperature extremes - ensuring reliable performance in jet engine bays, missile canisters, and space vehicle power systems where ambient conditions exceed commercial-grade limits.
Does 5962-85127023A require external calibration components?
No, the 5962-85127023A contains factory-trimmed thin-film resistors and an internal 10 V buried Zener reference, enabling full 12-bit operation without external precision components. Offset and full-scale trims are optional: unipolar offset is adjustable via Pin 12, and full-scale calibration uses a 50 Ω resistor between Pins 8 and 10 - both are only needed if tighter than ±1 LSB error is required.
How does the 12/8 pin affect data output formatting for 5962-85127023A?
The 12/8 pin on 5962-85127023A determines data organization: when tied to VLOGIC, it enables 12-bit parallel output on DB11–DB0; when tied to Digital Common, it configures the device for 8-bit bus compatibility - outputting the 8 MSBs when A0 = 0 and the 4 LSBs + 4 trailing zeroes when A0 = 1. This pin is not TTL-compatible and must be hard-wired.
Can 5962-85127023A operate from ±12 V supplies instead of ±15 V?
Yes, 5962-85127023A supports both ±12 V and ±15 V supply configurations per its absolute maximum ratings and operating specifications. However, when using ±12 V, the internal reference output current capability drops - an external buffer amplifier is recommended if driving loads >1.5 mA or requiring full temperature-range stability, as stated in the AD574A datasheet Note 3.
What is the guaranteed no-missing-codes resolution for 5962-85127023A?
The 5962-85127023A guarantees no missing codes to 11-bit resolution over its full –55°C to +125°C operating range. This means all 2048 combinations of the upper 11 bits appear monotonically as the analog input increases - sufficient for most closed-loop control applications where 12-bit resolution is desired but monotonicity is critical.
