ADI 5962-8778902EA
- CMOS 8-bit buffered multiplying DAC with R-2R inverted ladder architecture
- Direct microprocessor bus interface — load cycle identical to RAM write cycle
- 2- and 4-quadrant multiplication with full ±VREF input range
- Ultra-low power: less than 10 mW typical — CMOS efficiency across full temperature range
- MIL-STD-883 Class B qualified under SMD 5962-87789 — 20-lead ceramic LCC package
- Military temperature range: –55°C to +125°C
The ADI 5962-8778902EA is the military SMD procurement designation for Analog Devices' AD7524TE processed to MIL-STD-883 Class B, housed in a 20-lead ceramic LCC package and rated for the full military temperature range. The AD7524 is one of the most widely deployed 8-bit multiplying DACs in defense electronics — a product that has earned its place on military bills of materials not through complexity, but through the combination of interface simplicity, low power, and guaranteed monotonicity across the entire –55°C to +125°C operating range.
The defining characteristic of the AD7524 architecture is how naturally it integrates with microprocessor-based systems. Its load cycle is structurally identical to a RAM write operation — chip select, write strobe, data bus — which means any processor that can write to memory can drive the DAC without additional interface logic. The inverted R-2R ladder structure switches binarily weighted currents between two output nodes, supporting both unipolar binary and bipolar offset binary configurations through simple external resistor networks. With less than 10 mW typical power consumption and no protection Schottky required, the 5962-8778902EA is a clean, low-overhead analog output solution for military embedded systems where every milliwatt and every component on the board matters.

Few components have the longevity of the AD7524 in military electronics. Originally introduced as a straightforward CMOS multiplying DAC, it became a default choice for 8-bit analog output in microprocessor-based military systems precisely because it asks so little of the designer: a standard bus write cycle, a reference voltage, an op-amp output stage, and it works — across the full military temperature range, with monotonicity guaranteed. The ADI 5962-8778902EA brings that same reliability into the DoD qualified parts framework, processed to MIL-STD-883 Class B under SMD 5962-87789 in a 20-lead ceramic LCC package.
5962-8778902EA Architecture: Multiplying DAC for Flexible Analog Output
The AD7524’s inverted R-2R ladder switches current between OUT1 and OUT2 rather than to ground — a design choice that keeps the total current in each ladder leg constant regardless of the digital code, improving linearity and reducing code-dependent glitch energy. This architecture directly enables 4-quadrant multiplication: by applying an AC reference voltage instead of a DC reference, the DAC output becomes the product of the digital code and the reference waveform, which is the operating principle behind programmable gain amplifiers, amplitude modulators, and digitally controlled attenuators. The TE grade of the 5962-8778902EA specifies ±1/4 LSB endpoint linearity — a meaningful accuracy step up from the standard SQ/SE grades — making it the correct choice for designs where DAC linearity directly impacts system-level signal quality.
5962-8778902EA in Mixed-Signal Military Designs
The 5962-8778902EA fits naturally alongside other qualified ADI mixed-signal components in military signal chain designs. For systems that require a precision voltage reference to drive the AD7524’s VREF input, the 5962-9078501MLA AD780S provides a stable 2.5V reference with 3 ppm/°C maximum drift in the same military qualification framework. Where the design also needs analog-to-digital conversion, the 5962-9451801MLA AD7572S 12-bit ADC and the 5962-8770002EA AD7226 quad 8-bit DAC complete a fully qualified mixed-signal subsystem from a single supplier with consistent documentation standards.

Frequently Asked Questions (FAQ)
What Is the ADI 5962-8778902EA and What Is Its Commercial Equivalent?
The 5962-8778902EA is the military SMD procurement designation for Analog Devices’ AD7524TE processed to MIL-STD-883 Class B, under drawing 5962-87789. It is an 8-bit CMOS buffered multiplying DAC with direct microprocessor bus interface, guaranteed monotonicity across the military temperature range, and ±1/4 LSB endpoint linearity in the TE accuracy grade, housed in a 20-lead ceramic LCC package.
What Is the Difference Between the 5962-8778902EA and the 5962-8770002EA?
The 5962-8770002EA is the military designation for the AD7226 — a quad 8-bit DAC with four independent voltage output channels and laser-trimmed output amplifiers. The 5962-8778902EA is the AD7524 — a single-channel multiplying DAC with current outputs designed for 2- and 4-quadrant multiplication applications. Choose the AD7226/5962-8770002EA when you need multiple independent voltage outputs; choose the AD7524/5962-8778902EA when you need multiplying DAC capability or a single-channel current output for a custom output stage.
What Does “Multiplying DAC” Mean and Why Does It Matter?
A multiplying DAC treats the reference voltage as a variable input rather than a fixed supply. The digital code sets the gain factor, and the output is the product of the code and the reference. This makes the AD7524 useful not just as a static DAC but as a programmable gain element, a digitally controlled attenuator, or an amplitude modulator — functions that would otherwise require dedicated multiplier ICs.
Does the 5962-8778902EA Require External Trimming?
No. The AD7524’s thin-film R-2R ladder is laser-trimmed at manufacture to achieve its specified linearity. Endpoint linearity to ±1/4 LSB is guaranteed for the TE grade without external adjustment. The only external components needed for basic operation are an output op-amp and power supply decoupling capacitors.
