Analog Devices Inc. 5962-8961601VA

Overview

5962-8961601VA from Analog Devices is a MIL-STD-883 qualified, Class B monolithic CMOS 8-bit analog-to-digital converter with microprocessor-compatible interface, 6 µs conversion time, ±0.5 LSB integral nonlinearity, and operation across –55°C to +125°C for defense-grade data acquisition in avionics sensor signal chains.

For engineers reviewing the 5962-8961601VA datasheet, 5962-8961601VA pinout, 5962-8961601VA application, or 5962-8961601VA equivalent, key selection criteria include unipolar input range compatibility, static RAM mode timing (tC = 6 µs, tRAD = 140 ns @ 20 pF), dual-ground architecture (AGND/DGND), and GDIP1-T18 18-pin ceramic DIP packaging for high-reliability embedded systems.

Technical Context

This device implements a successive-approximation ADC architecture with internal track-and-hold, reference buffer, and parallel digital output. It supports three interface modes-static RAM, slow-memory, and ROM-with CS/RD control logic and BUSY status flag for synchronous microprocessor handshaking.

It requires separate analog and digital ground planes (AGND/DGND ≤ 0.3 V differential), accepts –10 V reference voltage at VREF, and operates from a single +5 V supply. Clock interface uses external RC network (RCLK = 43 kΩ for device type 01) to generate internal timing, eliminating need for external clock generator.

FAQ

What is the maximum clock frequency supported by 5962-8961601VA?

The 5962-8961601VA does not accept an external clock signal; instead, it uses an RC network (RCLK = 43 kΩ, CCLK = 100 pF) to generate internal timing. This yields a fixed 1.35 MHz internal clock, enabling its 6 µs conversion time. No external clock source is connected to the CLK pin-only passive components are used.

Does 5962-8961601VA require separate analog and digital power supplies?

No, the 5962-8961601VA operates from a single +5 V DC supply (VDD). However, it mandates physically separate analog ground (AGND) and digital ground (DGND) connections, with strict limit of ≤0.3 V dc potential difference between them to preserve ADC accuracy and noise immunity.

Can 5962-8961601VA interface directly with a modern microcontroller GPIO bus?

Direct GPIO interfacing is not recommended. The 5962-8961601VA expects TTL-compatible static RAM bus timing (e.g., 8080/8085), including precise setup/hold windows for CS and RD. Modern microcontrollers typically require FPGA or CPLD glue logic to replicate these timing waveforms and manage BUSY handshaking reliably.

What is the purpose of the BOFS pin on 5962-8961601VA?

The BOFS (Bias Offset) pin on 5962-8961601VA connects to VREF through an external resistor to calibrate gain and offset errors. It enables two-point calibration (zero and full-scale) without trimming internal components, supporting field recalibration in deployed systems where long-term drift must be corrected.

Is 5962-8961601VA RoHS compliant?

No-5962-8961601VA is a legacy military-specification part manufactured in a hermetic ceramic DIP package with leaded (SnPb) terminations per MIL-PRF-38535 Appendix A. It is exempt from RoHS under EU Directive 2011/65/EU Annex III for aerospace and defense applications requiring high-reliability packaging.
