Product details
Overview
5962-8850501RA from Analog Devices is a military-grade 10-bit successive approximation analog-to-digital converter (ADC) with integrated buried Zener reference, on-chip clock, and comparator. It delivers ±1 LSB relative accuracy, 20 µs typical conversion time, and supports both unipolar (0 V to +10 V) and bipolar (–5 V to +5 V) input ranges. It is used in precision data acquisition systems for aerospace telemetry, avionics sensor interfaces, and ruggedized test instrumentation.
For engineers reviewing the 5962-8850501RA datasheet, 5962-8850501RA pinout, 5962-8850501RA application, or 5962-8850501RA equivalent, this page provides verified technical context, MIL-STD-883-compliant specifications, functional pin mapping, real-world interface timing constraints, and validated alternatives for high-reliability embedded ADC selection.
Technical Context
The 5962-8850501RA implements successive approximation using integrated injection logic (I2L) SAR architecture, with a laser-trimmed SiCr thin-film resistor ladder and temperature-compensated subsurface Zener reference. Its 10-bit current-output DAC compares against analog input via a high-stability comparator, delivering no missing codes across –55°C to +125°C.
It operates from +5 V and –12 V to –15 V supplies, accepts analog inputs referenced to separate analog common, and uses three-state output buffers controlled by HIGH BYTE ENABLE (HBE) and LOW BYTE ENABLE (LBE). DATA READY (DR) signals conversion completion with 1.5 µs delay after CONVERT pulse rising edge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10 bits - guarantees full 1024-step quantization without interpolation or averaging. |
| Relative Accuracy | ±1 LSB - ensures code transition points deviate ≤ ±0.1% of full scale over temperature. |
| Conversion Time | 20 µs typ - enables sampling rates up to 50 kSPS in deterministic timing-critical systems. |
| Analog Input Range | Unipolar: 0 V to +10 V; Bipolar: –5 V to +5 V - selectable via Pin 16 (BIP OFF) open/grounded. |
| Supply Voltages | V+ = +5 V; V– = –12 V to –15 V - dual-rail operation eliminates need for external level-shifting. |
| Temperature Range | –55°C to +125°C - qualified per MIL-STD-883, suitable for extended-environment flight control units. |
| Output Coding | Unipolar: Positive true binary; Bipolar: Positive true offset binary - direct compatibility with standard microprocessor arithmetic. |
Pinout & Package
5962-8850501RA is housed in a 20-pin hermetically sealed side-brazed ceramic dual in-line package (SBDIP), designated D-20 per JEDEC MS-001, with 0.300-inch body width and 0.100-inch lead pitch. The package provides hermeticity and thermal stability required for military and space applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (DB0) | LSB Data Output | Least significant bit of 10-bit conversion result; enabled only when LBE is low. |
| Pin 2 (DB1) | 2nd LSB Data Output | Second least significant bit; part of 2-bit low-byte bus segment. |
| Pin 3–10 (DB2–DB9) | MSB Data Outputs | Bits 2 through 9 (DB2–DB9); collectively form 8-bit high byte enabled by HBE. |
| Pin 11 (V–) | Negative Supply Rail | Connects to –12 V to –15 V supply; powers internal DAC, reference, and comparator circuitry. |
| Pin 12 (ANALOG COM) | Analog Common Reference | Return path for analog input current; carries up to 2 mA transient during conversion. |
| Pin 13 (BIP OFF) | Bipolar Offset Control | Open = bipolar mode (–5 V to +5 V); grounded = unipolar mode (0 V to +10 V). |
| Pin 14 (ANALOG IN) | Analog Input Terminal | Accepts input current via internal 5 kΩ trimmed thin-film resistor; impedance 3–7 kΩ. |
| Pin 15 (DIG COM) | Digital Common Reference | Ground reference for logic inputs/outputs; isolated from ANALOG COM to minimize noise coupling. |
| Pin 16 (CONVERT) | Start Conversion Trigger | Positive pulse ≥500 ns wide; falling edge initiates SAR cycle; rising edge resets internal logic. |
| Pin 17 (DR) | Data Ready Indicator | Active-low open-collector output; goes low 20 µs after CONVERT falling edge to signal valid data. |
| Pin 18 (LBE) | Low-Byte Enable | Active-low control for DB0–DB1 outputs; must be high during conversion to avoid bus contention. |
| Pin 19 (HBE) | High-Byte Enable | Active-low control for DB2–DB9 outputs; enables 8-bit segment compatible with 8-bit microprocessor buses. |
| Pin 20 (V+) | Positive Supply Rail | Connects to +5 V supply; powers digital logic, output buffers, and internal reference biasing. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit successive approximation ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD573SD | Same die, same D-20 package, but screened to MIL-STD-883 Class B (not Class S); ±1 LSB accuracy guaranteed only from –40°C to +85°C. | Approved for non-safety-critical ground-based military systems; not qualified for flight hardware per MIL-PRF-38535. | Select AD573SD only if full Class S screening and –55°C to +125°C guarantee are not required. |
| MAX160A | 10-bit SAR ADC with internal reference; requires +5 V only; conversion time 25 µs; no bipolar input support; plastic DIP package. | Suitable for commercial industrial controllers; lacks hermeticity, extended temperature, and bipolar range needed for aerospace use. | Choose MAX160A only for cost-sensitive, non-military applications where single-supply operation and lower performance are acceptable. |
Compared with AD573SD and MAX160A, the 5962-8850501RA uniquely combines MIL-STD-883 Class S screening, hermetic SBDIP packaging, guaranteed ±1 LSB accuracy over –55°C to +125°C, and hardware-selectable bipolar/unipolar input - making it irreplaceable in certified flight-critical signal chains.

FAQ
What is the guaranteed operating temperature range for the 5962-8850501RA?
The 5962-8850501RA is fully specified and tested from –55°C to +125°C per MIL-STD-883 screening requirements. This range is guaranteed for all electrical parameters including relative accuracy (±1 LSB), conversion time (10–30 µs), and input range integrity. No derating or additional qualification is required for operation within this envelope.
Does the 5962-8850501RA require external components to achieve full 10-bit accuracy?
No. The 5962-8850501RA integrates a buried Zener reference, on-chip clock generator, comparator, 10-bit current-output DAC, and successive approximation register. Only power supplies (+5 V and –12 V to –15 V), analog input, and CONVERT trigger are required for full-accuracy operation - no external resistors, capacitors, or trimming networks are needed for basic functionality.
How is bipolar versus unipolar input range selected on the 5962-8850501RA?
Bipolar (–5 V to +5 V) or unipolar (0 V to +10 V) input range is selected solely by the state of Pin 16 (BIP OFF): leaving it open configures bipolar mode with offset binary coding; grounding it to DIG COM selects unipolar mode with true binary coding. No external switches, jumpers, or logic gates are required.
What is the purpose of the DATA READY (DR) signal on the 5962-8850501RA?
DATA READY (DR) is an active-low open-collector output that transitions low 20 µs after the falling edge of the CONVERT pulse, signaling completion of the 10-bit conversion. It enables interrupt-driven data reads, eliminates polling delays, and can directly drive HBE/LBE for "stand-alone" auto-read operation - critical for deterministic real-time systems.
Can the 5962-8850501RA interface directly to an 8-bit microprocessor bus?
Yes. The 5962-8850501RA supports native 8-bit bus interfacing via separate HIGH BYTE ENABLE (HBE) and LOW BYTE ENABLE (LBE) controls. DB2–DB9 (8 MSBs) are enabled by HBE; DB0–DB1 (2 LSBs) by LBE. This allows sequential reading of high and low bytes without external latches or multiplexers - demonstrated with 6502 and 8085 systems in official Analog Devices application notes.
