ADI 5962-9475501MPA

Sixteen-bit monotonicity over the military temperature range is the specification that separates the AD7846 from most 16-bit DAC alternatives. For engineers designing closed-loop military systems — servo controllers, precision calibrators, guidance analog stages — a DAC that drops out of monotonicity at temperature extremes introduces code-dependent errors that are difficult to detect and impossible to calibrate away. The ADI 5962-9475501MPA resolves this at the architecture level, not the trimming level, making it a reliable choice for military designs that operate at both ends of the –55°C to +125°C range. Processed to MIL-STD-883 Class B under SMD 5962-94755 and housed in a 28-lead ceramic DIP, it brings the AD7846’s precision performance into the DoD qualified parts framework.

5962-9475501MPA Architecture: Why Segmented Design Matters for 16-Bit Monotonicity

The AD7846’s segmented architecture divides the 16-bit conversion into two stages. The four MSBs drive a pair of 4-bit DACs that select adjacent nodes on a 16-element resistor string — a structure that is inherently monotonic because the resistor string produces a continuous, monotonically increasing voltage sequence. The 12-bit interpolating DAC then divides the voltage between those two nodes to provide the remaining resolution. Because monotonicity at the segment boundaries depends on the resistor string geometry rather than on absolute resistor value matching, the architecture maintains its monotonicity guarantee across temperature shifts that would cause trimmed R-2R ladders to violate the monotonicity condition. The built-in deglitch track-and-hold further improves dynamic behavior by holding the output at its previous value for approximately 2.5 µs after the LDAC edge, suppressing internal switching transients before they appear at the output.

5962-9475501MPA vs Other Military 16-Bit DAC Options

For programs evaluating 16-bit DAC options in the military qualified space, the AD7846 and AD766 represent complementary architectures addressing different interface requirements:

The 5962-9475501MPA is the correct choice when the application requires flexible output voltage ranges, readback capability, multi-DAC simultaneous update, or the widest available output swing. The AD766/5962-9201601MEA is the better fit for DSP-driven serial interface designs where output range is fixed and dynamic SNR performance is the priority.

Frequently Asked Questions (FAQ)

What Is the ADI 5962-9475501MPA and What Is Its Commercial Equivalent?

The 5962-9475501MPA is the military SMD procurement designation for Analog Devices’ AD7846SD, processed to MIL-STD-883 Class B under drawing 5962-94755. It is a 16-bit LC2MOS voltage output DAC with segmented architecture, guaranteed 16-bit monotonicity over the military temperature range, flexible unipolar and bipolar output ranges, and a 16-bit parallel microprocessor interface with readback capability, in a 28-lead ceramic DIP package.

How Does the AD7846 Achieve 16-Bit Monotonicity Over the Military Temperature Range?

The segmented architecture uses a 16-resistor string to handle the four MSBs — a structure that is inherently monotonic because adjacent string nodes always maintain a voltage ordering that cannot be reversed by temperature drift. This is structurally different from R-2R ladders, where monotonicity depends on tight resistor ratio matching that can be violated at temperature extremes. The 12-bit interpolating DAC then operates within each segment boundary, inheriting the segment-level monotonicity guarantee.

What Is the Readback Capability and When Is It Useful?

The AD7846 allows the current contents of its DAC input register to be read back through the same 16-bit parallel bus used to write data. In ATE systems, this allows the controller to verify that the correct code was loaded without a separate readback path. In multi-DAC closed-loop systems, it simplifies state tracking during fault recovery or system initialization.

How Does the 5962-9475501MPA Compare to the 5962-9201601MEA AD766?

The 5962-9201601MEA AD766 is a complete DSP DACPORT with a three-wire serial interface, built-in voltage reference, and fixed ±3V output — optimized for direct connection to DSP serial ports with minimum component count. The 5962-9475501MPA AD7846 uses a 16-bit parallel interface, requires an external reference, and offers flexible ±5V/±10V output ranges with 16-bit guaranteed monotonicity and readback. The choice depends on the interface available in the system and the output range and accuracy requirements.
