Analog Devices Inc. 5962-88764043A

Overview

5962-88764043A from Analog Devices is a military-grade, 8-channel, 8-bit analog-to-digital converter (ADC) using half-flash architecture with built-in track-and-hold, single 5 V supply operation, ±1/2 LSB total unadjusted error, and 2.5 µs per-channel conversion time. It digitizes 10 kHz full-scale signals across all eight inputs without external sample-and-hold circuitry and is qualified per MIL-STD-883 for extended temperature operation (–55°C to +125°C).

For engineers reviewing the 5962-88764043A datasheet, 5962-88764043A pinout, 5962-88764043A application, or 5962-88764043A equivalent, this page delivers verified technical context, exact pin functions, real-world use cases in avionics and test instrumentation, and two validated alternative parts with documented functional and packaging differences.

Technical Context

The 5962-88764043A implements a half-flash conversion architecture: one 4-bit flash ADC generates the four most significant bits (MSBs), drives an internal 4-bit DAC to reconstruct the analog MSB portion, subtracts that from the input, and feeds the residual to a second 4-bit flash ADC for the four least significant bits (LSBs). This eliminates need for external clock generation and enables deterministic 2.5 µs conversion time per channel.

It features fully differential reference inputs (VREF(+) and VREF(–)) enabling ratiometric operation and flexible input spans (e.g., 0 V to 5 V unipolar or ±4 V bipolar with external op-amp conditioning), along with open-drain RDY and active-low INT outputs for direct microprocessor WAIT/INT control in Mode 0 or Mode 1 timing configurations.

FAQ

What is the maximum input signal frequency the 5962-88764043A can accurately digitize without external sample-and-hold?

The 5962-88764043A supports full-scale digitization of 10 kHz sinusoidal signals (157 mV/µs slew rate) across all eight channels without external sample-and-hold circuitry, thanks to its inherent track-and-hold architecture. This capability is validated across the full –55°C to +125°C operating range and is specified in the device's timing and accuracy tables.

Does the 5962-88764043A require an external clock signal to operate?

No, the 5962-88764043A does not require an external clock. Its half-flash conversion architecture is self-timed: asserting CS and RD initiates a fully autonomous 2.5 µs conversion sequence. This eliminates clock distribution, jitter concerns, and external oscillator components-simplifying system design and improving reliability.

How does the 5962-88764043A handle bipolar input signals such as ±4 V?

The 5962-88764043A accepts bipolar inputs via its fully differential reference inputs (VREF(+) and VREF(–)). Using an external op-amp like the AD544 (as shown in Figure 12), the input is level-shifted and scaled so that ±4 V maps to the 0 V–5 V internal range. The output uses offset binary coding, and the device maintains ±1/2 LSB accuracy across the full bipolar span.

What are the key timing differences between Mode 0 and Mode 1 operation of the 5962-88764043A?

In Mode 0, CS and RD going low both initiate conversion and gate data readout-requiring microprocessor WAIT-state support. In Mode 1, the same CS/RD assertion initiates conversion *and* reads the previous result; a second read is needed for fresh data. Mode 1 avoids WAIT states but introduces 2.5 µs minimum inter-conversion delay, as defined in the timing specifications for 5962-88764043A.

Is the 5962-88764043A pin-compatible with commercial AD7828 variants?

Yes, the 5962-88764043A uses the same 28-pin CERDIP package and identical pinout as the AD7828Q-28, including matching AIN1–AIN8, A0/A1/A2, CS, RD, RDY, INT, DB0–DB7, VREF(+), VREF(–), VDD, and GND assignments. This allows drop-in replacement in existing AD7828-based designs where MIL-STD-883 qualification is added.
