Analog Devices Inc. 5962-8512702XA

Overview

5962-8512702XA from Analog Devices is a military-grade 12-bit monolithic analog-to-digital converter with on-chip reference, successive-approximation architecture, and ±5 V or ±10 V bipolar/unipolar input ranges. It delivers guaranteed ±1 LSB linearity over –55°C to +125°C, 35 µs max 12-bit conversion time, and internal 10.00 V ±0.02 V buried Zener reference - used in precision telemetry, avionics data acquisition, and radiation-tolerant instrumentation.

For engineers reviewing the 5962-8512702XA datasheet, 5962-8512702XA pinout, 5962-8512702XA application, or 5962-8512702XA equivalent, this page provides verified electrical specs, MIL-STD-883B qualified package details (Ceramic DIP, D-28), unipolar/bipolar calibration guidance, and direct alternatives for high-reliability analog front-end design.

Technical Context

The 5962-8512702XA implements a fully self-contained successive-approximation ADC with integrated 12-bit current-output DAC, comparator, clock generator, and control logic. Its SAR core sequences MSB-to-LSB bit testing using internal thin-film trimmed resistors and a temperature-compensated buried Zener reference.

It supports dual data modes: 12-bit parallel output or byte-accessible 8-bit/4-bit nibble reads via AO and 12/8 control pins, with STS status flag signaling conversion completion. Input impedance is 5 kΩ (10 V span) or 10 kΩ (20 V span), requiring low-impedance driving sources or external sample-and-hold (e.g., AD585) for dynamic signals above 1.5 Hz.

FAQ

What is the operating temperature range certified for the 5962-8512702XA?

The 5962-8512702XA is qualified per MIL-STD-883B for continuous operation from –55°C to +125°C. All specifications - including ±1 LSB linearity error, 10.00 V reference stability, and 35 µs conversion time - are guaranteed across this full range. This exceeds commercial AD574A variants (e.g., AD574AJ: 0°C to +70°C) and supports deployment in jet engine bays, re-entry vehicles, and reactor containment zones where ambient extremes are routine. The 5962-8512702XA maintains performance without derating.

Does the 5962-8512702XA require external calibration components?

The 5962-8512702XA includes factory-trimmed thin-film resistors and an internal 10.00 V ±0.02 V reference, so full calibration is optional. For unipolar operation, only a 50 Ω ±1% resistor between Pins 8 (REF OUT) and 10 (REF IN) is needed to set full-scale gain. Offset trim (Pin 12) is optional and provides ±15 mV adjustment range. No external op amps, references, or DACs are required - the 5962-8512702XA functions as a complete ADC subsystem.

How does the 5962-8512702XA handle analog input drive requirements?

The 5962-8512702XA exhibits dynamic loading at its analog input due to internal DAC switching, requiring a low-impedance source (<50 Ω) to hold voltage steady within ±1/2 LSB during conversion. For signals above 1.5 Hz or high-impedance sources (e.g., thermocouples), an external sample-and-hold like the AD585 is mandatory. The 5962-8512702XA's 5 kΩ (10 V span) or 10 kΩ (20 V span) input impedance alone is insufficient for accurate 12-bit acquisition of dynamic waveforms.

Can the 5962-8512702XA interface directly with an 8-bit microprocessor bus?

Yes - the 5962-8512702XA supports native 8-bit interfacing via its AO and 12/8 control pins. When 12/8 is tied to DIGITAL COMMON (Pin 15), data appears as two 8-bit words: AO = 0 enables DB11–DB4 (MSBs), AO = 1 enables DB3–DB0 plus four trailing zeroes. This eliminates external latches or bus transceivers. The 5962-8512702XA's TTL-compatible outputs and STS handshake signal ensure robust timing with legacy 8080/Z80-style systems.

What package type and lead finish does the 5962-8512702XA use?

The 5962-8512702XA is supplied in a hermetically sealed Ceramic Dual-In-Line Package (D-28), per MIL-STD-1835. Leads are tin-lead (SnPb) finished, qualified for soldering per MIL-STD-202, Method 210. The package features a glass-sealed ceramic body with gold-plated leads, rated for storage from –65°C to +150°C and capable of withstanding 300°C for 10 seconds during wave soldering. This construction ensures long-term reliability in high-humidity, high-vibration, and radiation environments.
