Product details

Overview

5962-8876401LX from Analog Devices is a military-grade, 8-channel, 8-bit analog-to-digital converter (ADC) with built-in track-and-hold, single 5 V supply operation, ±1/2 LSB total unadjusted error, 2.5 µs conversion time per channel, and operation across –55°C to +125°C. It serves as a high-speed data acquisition front-end in avionics sensor interfaces and ruggedized telemetry systems.

For engineers reviewing the 5962-8876401LX datasheet, 5962-8876401LX pinout, 5962-8876401LX application, or 5962-8876401LX equivalent, this page delivers verified technical context, military-spec package details, timing-critical interface guidance, and validated alternatives for MIL-STD-883B-compliant embedded acquisition designs.

Technical Context

The 5962-8876401LX implements a half-flash architecture using two cascaded 4-bit flash ADCs - one for MSBs and one for LSBs - with an internal 4-bit DAC reconstructing the MSB analog value for residual subtraction. This eliminates external clock requirements and enables deterministic 2.5 µs conversion latency.

It supports dual operational modes: Mode 0 uses RDY/INT status outputs to assert microprocessor WAIT/DTACK signals, while Mode 1 decouples conversion initiation from data readback via address latching on RD rising edge - critical for real-time TMS32010 and Z80-based flight control firmware.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 8-bit multichannel ADC applications.

Alternative Part Technical Difference Application Difference Selection Advice
AD7828TQ Same die, plastic DIP (Q-28) package; not MIL-STD-883B screened; –55°C to +125°C temp range retained. Lacks DESC qualification, burn-in, and lot acceptance testing - unsuitable for flight-critical hardware but acceptable for ground-test benches. Select AD7828TQ only for non-mission-critical prototyping or lab validation where cost and lead time outweigh qualification requirements.
MAX195BCPI+ 5 V, 16-bit, 100 kSPS SAR ADC; serial SPI interface; no built-in track-and-hold; higher resolution but slower effective throughput per channel. Requires external driver op-amp and anti-alias filter; incompatible pinout and timing model - redesign needed for drop-in replacement. Choose MAX195BCPI+ only when 16-bit resolution and lower noise floor justify added signal chain complexity and firmware changes.

Compared with AD7828TQ, 5962-8876401LX provides guaranteed radiation tolerance, lot traceability, and extended life testing - making it irreplaceable in flight hardware. Against MAX195BCPI+, 5962-8876401LX offers deterministic latency, no external clock, and integrated track-and-hold - essential for real-time control loops.

FAQ

What is the military specification compliance status of the 5962-8876401LX?

The 5962-8876401LX is fully compliant with U.S. Standard Military Drawing (SMD) #5692-88764 and qualified per MIL-STD-883B, including Methods 1015.8 (temperature cycling), 2001.5 (preconditioning), and 5005.3 (steady-state life). It carries DESC certification and is processed to /883B standards - confirming its suitability for flight-critical avionics hardware.

Does the 5962-8876401LX require an external clock signal to operate?

No, the 5962-8876401LX does not require an external clock. Its half-flash conversion architecture internally generates timing for both the 4-bit MSB and LSB flash ADC stages. Conversion is initiated solely by CS and RD control signals - eliminating clock distribution, jitter sensitivity, and associated PCB layout constraints.

What is the maximum analog input frequency the 5962-8876401LX can digitize without external sample-and-hold?

The 5962-8876401LX supports full-scale analog input frequencies up to 10 kHz per channel without external sample-and-hold circuitry. This is enabled by its inherent track-and-hold function, which stabilizes the selected input for ~1 µs after conversion start - sufficient for signals with ≤157 mV/µs slew rate.

How does the 5962-8876401LX handle channel selection in Mode 1 operation?

In Mode 1, the 5962-8876401LX latches the A0, A1, and A2 address inputs on the rising edge of the RD signal. A READ operation initiates conversion on the newly selected channel while simultaneously outputting the result from the previous conversion on DB0–DB7 - enabling non-blocking, pipelined acquisition ideal for TMS32010-based systems.

What reference configuration options does the 5962-8876401LX support?

The 5962-8876401LX supports fully differential reference inputs (VREF (+) and VREF (–)), enabling unipolar (0 V to VREF span), bipolar (±VREF/2), or offset-adjusted ranges. Ratiometric operation is supported by tying VREF (–) to sensor excitation - critical for bridge-based transducers in flight control surface monitoring.
