ADI 5962-9684601QLA

The AD660 was designed around a specific problem in multi-channel military analog output design: how to update several 16-bit DAC outputs simultaneously, from either a serial or parallel interface, with a single qualified component that includes its own precision reference. The ADI 5962-9684601QLA delivers that in a 24-lead ceramic DIP under MIL-STD-883B — a complete DACPORT that eliminates the external reference, output amplifier, and interface logic that discrete implementations require, while adding the interface flexibility that military system designers actually need across different processor architectures.

5962-9684601QLA Architecture: Dual-Mode Interface and Daisy-Chain Capability

The AD660’s interface architecture is the feature that separates it from single-mode alternatives. Serial mode accepts a continuous bitstream with pin-selectable MSB-first or LSB-first data direction, and the serial output pin passes data through to the next device in a chain — allowing multiple AD660s to be loaded from three control lines (SIN, CS, LDAC) regardless of how many devices are in the chain. Byte mode accepts 16-bit data as two sequential 8-bit transfers, compatible with both 8-bit and 16-bit processor buses. Both modes use the same double-buffered latch structure: data loads into the first-rank latch transparently, and the LDAC edge transfers all first-rank latches to the DAC registers simultaneously across every device in a multi-DAC system. The asynchronous CLR function resets all outputs to 0V regardless of the programmed output range mode — a useful fault response capability in military systems where a defined safe output state is required on command.

5962-9684601QLA vs Other Military 16-Bit DAC Options

The AD660 occupies a distinct position among military 16-bit DACs by combining the widest interface flexibility with the highest output voltage swing:

For multi-DAC military systems where all channels must update simultaneously from a serial interface with minimum control line count, the AD660 daisy-chain capability is a practical architectural advantage. For applications requiring the widest output range — particularly systems driving ±10V actuators or analog buses — the AD660’s bipolar swing matches the requirement directly.

Frequently Asked Questions (FAQ)

What Is the ADI 5962-9684601QLA and What Is Its Commercial Equivalent?

The 5962-9684601QLA is the military SMD procurement designation for Analog Devices’ AD660SQ, processed to MIL-STD-883B under drawing 5962-96846. It is a complete 16-bit serial/byte DACPORT integrating a laser-trimmed 10V buried Zener reference, 16-bit BiMOS II DAC core, double-buffered latches, and a voltage output amplifier with pin-programmable 0V to +10V or –10V to +10V output range, in a 24-lead ceramic DIP package rated for military operation from –55°C to +125°C.

How Does the AD660 Daisy-Chain Feature Work?

In serial mode, after data is clocked into the AD660’s input latch, it continues shifting out through the serial output (SOUT) pin to the serial input (SIN) of the next device in the chain. Any number of AD660s can be cascaded this way, with each device requiring 16 clock cycles to load. All devices share the same CS and LDAC control lines, so a single LDAC edge simultaneously transfers all first-rank latches to DAC registers across the entire chain — enabling phase-coherent multi-channel output updates with minimum control line overhead.

How Does the 5962-9684601QLA Compare to the 5962-9475501MPA AD7846?

The 5962-9475501MPA AD7846 guarantees 16-bit monotonicity over temperature (versus 15-bit for the AD660), supports readback, and offers more output range options — making it the preferred choice for closed-loop precision control and ATE applications. The AD660 is the better fit when daisy-chain serial interface capability, ±10V output swing, or on-chip reference availability are the system requirements.

What Processor Interfaces Are Compatible With the 5962-9684601QLA?

The AD660 has been characterized and demonstrated with ADSP-210x family DSPs, MC68HC11 SPI bus, National Semiconductor MICROWIRE, and Z80 bus architectures. In byte mode, any 8-bit or 16-bit parallel processor bus can drive the AD660 directly. In serial mode, any processor with an SPI-compatible or software-bitbang serial output can interface without glue logic.
