Overview

5962-88650012A from Analog Devices is a military-grade 8-bit sampling analog-to-digital converter (ADC) with 2 µs conversion time, specified for operation across –55°C to +125°C, housed in a 20-pin ceramic leadless chip carrier (CLCC) package, and used in precision data acquisition within avionics and missile guidance systems.

For engineers reviewing the 5962-88650012A datasheet, 5962-88650012A pinout, 5962-88650012A application, or 5962-88650012A equivalent, key selection criteria include MIL-STD-883 compliance, single-supply operation, track-and-hold integration, and guaranteed performance over full military temperature range without derating.

Technical Context

The 5962-88650012A implements a successive approximation register (SAR) architecture with integrated track-and-hold amplifier, enabling single-shot conversion without external sample-hold circuitry. It operates from a single +5 V supply and accepts unipolar 0 V to +5 V analog inputs.

Designed to meet MIL-PRF-38535 Class K requirements, the device features built-in reference buffer, TTL/CMOS-compatible digital outputs, and latch-enable control for synchronized data capture in real-time embedded control loops.

FAQ

What is the conversion architecture used in the 5962-88650012A?

The 5962-88650012A employs a successive approximation register (SAR) architecture with an integrated track-and-hold amplifier. This design enables precise, repeatable 8-bit conversions in 2 µs without external sampling components. Its SAR core ensures monotonicity and no missing codes across the full military temperature range, making the 5962-88650012A suitable for closed-loop control where deterministic timing and accuracy are mandatory.

Does the 5962-88650012A require an external reference voltage?

The 5962-88650012A can operate using either an internal +5 V reference derived from V_DD or an externally supplied reference applied to the REF IN pin. When using the internal reference, a 10 µF tantalum capacitor must be connected between REF IN and AGND. The 5962-88650012A does not include a precision bandgap reference, so external reference selection directly impacts absolute accuracy and temperature drift performance.

Is the 5962-88650012A pin-compatible with other AD7820 variants?

Yes-the 5962-88650012A shares identical pinout and signal definitions with all 20-pin AD7820 variants including 5962-8865001RA, 5962-88650022A, and AD7820TQ. This uniformity allows board-level substitution between ceramic leadless, CERDIP, and plastic packages when thermal, hermeticity, or qualification requirements change-provided layout accommodates package footprint differences.

What qualification standards apply to the 5962-88650012A?

The 5962-88650012A is manufactured and tested to MIL-PRF-38535 Class K and certified per MIL-STD-883, including Methods 1015 (steady-state life), 2003 (thermal shock), and 5005 (burn-in). These qualifications verify performance stability under mechanical stress, thermal cycling, and long-duration operation-critical for the 5962-88650012A's use in mission-critical defense platforms where field failure is unacceptable.

Can the 5962-88650012A interface directly with a 3.3 V FPGA?

No-the 5962-88650012A outputs TTL/CMOS levels referenced to its +5 V supply, producing logic-high voltages near 4.5 V minimum. Direct connection to a 3.3 V FPGA I/O bank risks overvoltage damage. A level-shifting buffer or resistive divider network is required to translate the 5962-88650012A's DB0–DB7 outputs to 3.3 V–compliant logic levels before interfacing with modern low-voltage FPGAs.
