Analog Devices Inc. 5962-8763501RA

Overview

5962-8763501RA from Analog Devices is a military-grade, complete 8-bit signal conditioning analog-to-digital converter with integrated instrumentation amplifier front end, precision voltage reference, successive approximation register (SAR), and three-state microprocessor bus interface. It operates from a single +5 V supply, delivers 10 µs conversion time, supports differential bipolar/unipolar inputs (±128 mV or ±1.28 V ranges), and guarantees no missing codes over –55°C to +125°C. It is used in ruggedized transducer interfaces for aerospace telemetry and missile guidance sensor conditioning.

For engineers reviewing the 5962-8763501RA datasheet, 5962-8763501RA pinout, 5962-8763501RA application, or 5962-8763501RA equivalent, key selection considerations include guaranteed no missing codes across military temperature range, factory-calibrated gain/offset (±1.5 LSB gain error @ +25°C), flexible input scaling without external trims, and direct 8-bit bus compatibility with STATUS and R/W/CS/CE control logic.

Technical Context

The 5962-8763501RA implements a dynamic SAR architecture using an inverter-based delay-line "one-shot" sequencing method-no external clock required-enabling deterministic 10 µs conversion. Its instrumentation amplifier front end provides high-impedance differential inputs (2.55 V range: 8–12 kΩ input resistance; 255 mV range: 200–500 nA bias current) and achieves ≥1 LSB common-mode rejection ratio across both input ranges.

Control is fully synchronous with microprocessor buses via R/W, CS, and CE signals; STATUS output indicates conversion progress; FORMAT and BPO/UPO pins configure output coding (2's complement/offset binary) and input polarity (bipolar/unipolar) per conversion cycle. All calibration is performed at wafer level using laser trimming of thin-film SiCr resistors, eliminating user trims.

FAQ

What is the qualified temperature range for 5962-8763501RA?

The 5962-8763501RA is fully specified and tested over –55°C to +125°C per MIL-STD-883B Class S requirements. All parameters-including relative accuracy (±½ LSB), gain error (±1.5 LSB), and no missing codes-are guaranteed across this range. This makes 5962-8763501RA suitable for high-altitude flight control and space launch vehicle applications where extreme thermal cycling occurs.

Does 5962-8763501RA require external calibration components?

No, the 5962-8763501RA requires no external trims or calibration components. Factory laser trimming of its thin-film SiCr resistor ladder ensures ±1.5 LSB gain accuracy and ±1.0 LSB zero error over temperature. The 5962-8763501RA integrates a precision voltage reference, instrumentation amplifier, DAC, SAR, and three-state buffers-all on a single die-eliminating need for external op amps, references, or trim pots.

How does the dynamic SAR architecture of 5962-8763501RA differ from conventional clocked SAR ADCs?

The 5962-8763501RA uses a dynamic SAR built from an inverter delay-line with tapped one-shots-no external clock is needed. This eliminates clock jitter sensitivity and reduces EMI susceptibility in noisy avionics environments. Conversion time is fixed at 10 µs, independent of process variation, unlike clocked SARs whose timing depends on external oscillator stability and PCB routing.

Can 5962-8763501RA interface directly to a floating bridge transducer?

Yes-the 5962-8763501RA's instrumentation amplifier front end accepts fully differential, floating inputs. For low-range configurations (e.g., ±128 mV), a 10 kΩ resistor from each input to ground provides the necessary DC bias return path. This allows direct connection to strain gauge bridges or RTDs without external instrumentation amps or level-shifting circuitry-verified in Figure 15 of the AD670 datasheet.

What packaging and screening standards apply to 5962-8763501RA?

The 5962-8763501RA is supplied in a 20-pin hermetically sealed ceramic DIP (D-20 package) and is screened per MIL-STD-883B Class S, including Method 1015 (hermeticity), Method 1008 (temperature cycling), and Method 1012 (burn-in). It complies with QML-38535 Level V flow for high-reliability microcircuits and is traceable to lot-level radiation hardness assurance data.
