Product details
Overview
5962-9475502MPA from Analog Devices is a military-grade, 12-bit successive-approximation ADC with 6 µs conversion time, single +5 V supply operation, on-chip track/hold amplifier, and high-speed two-wire serial interface (SCLK/SDATA). It supports ±10 V analog input range (AD7893-10 variant), delivers 70 dB SNR at 10 kHz, and is packaged in an 8-pin hermetic Cerdip (Q-8) for extended temperature operation (–55°C to +125°C). Used in precision data acquisition within avionics and ruggedized test instrumentation.
For engineers reviewing the 5962-9475502MPA datasheet, 5962-9475502MPA pinout, 5962-9475502MPA application, or 5962-9475502MPA equivalent, key selection criteria include its MIL-PRF-38535 Class S qualification, ±1 LSB relative accuracy, 1.5 µs track/hold acquisition time, buffered 2.5 V reference input, and compatibility with microcontroller serial interfaces requiring minimal board space.
Technical Context
The 5962-9475502MPA implements a laser-trimmed internal clock oscillator driving a 12-bit R-2R ladder SAR core, eliminating external timing components. Its on-chip track/hold operates with <15 ns aperture delay and acquires to ±1/2 LSB in ≤1.5 µs after conversion completion or input step change.
It uses a buffered, high-impedance REF IN input (2.375 V to 2.625 V, ≤2 µA max current) to set full-scale gain; analog input (VIN) accepts ±10 V with 16 kΩ minimum input resistance; digital I/O operates at TTL-compatible levels (VINH ≥ 2.4 V, VINL ≤ 0.8 V) and drives SDATA with 200 µA source / 1.6 mA sink capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - guarantees no missing codes over full operating range |
| Conversion Time | 6 µs max - enables 117 kHz maximum throughput with optimal timing |
| Analog Input Range | ±10 V - supports bipolar industrial sensor signals without external scaling |
| Signal-to-(Noise+Distortion) | 70 dB min at 10 kHz - meets precision measurement requirements for 12-bit fidelity |
| Relative Accuracy | ±1 LSB max - ensures endpoint linearity critical for calibration-critical systems |
| Power Dissipation | 25 mW typical - enables low-thermal-load deployment in sealed enclosures |
| Operating Temperature | –55°C to +125°C - qualified per MIL-PRF-38535 Class S for aerospace use |
Pinout & Package
5962-9475502MPA is housed in an 8-pin hermetic Cerdip package (Q-8), 0.3" wide, with centerline pitch of 0.1" and lead spacing compliant with MIL-STD-1835.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - REF IN | Voltage reference input | Accepts buffered +2.5 V ±5% reference; errors directly scale full-scale gain and inject offset in attenuator stage |
| 2 - VIN | Analog input channel | ±10 V input range with 16 kΩ min input resistance; connects to internal scaling resistors and track/hold front-end |
| 3 - AGND | Analog ground reference | Separate return path for track/hold, comparator, and DAC; must be isolated from DGND to minimize noise coupling |
| 4 - SCLK | Serial clock input | External clock up to 8.33 MHz; rising edge clocks out SDATA bit; falling edge validates data; must go low post-read |
| 5 - SDATA | Serial data output | Three-state CMOS output; provides 16-bit frame (4 leading zeros + 12-bit result, MSB first); disabled on 16th falling SCLK edge |
| 6 - DGND | Digital ground reference | Return for logic circuitry only; requires star grounding with AGND at single point to avoid digital noise injection |
| 7 - CONVST | Convert start control | Falling edge resets serial counter; rising edge initiates track→hold transition and starts conversion sequence |
| 8 - VDD | Positive supply | +5 V ±5%; powers all analog and digital sections; decoupling capacitor required close to pin |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply 12-bit SAR architecture | Eliminates dual-rail power design complexity while maintaining ±10 V input capability via internal resistor scaling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit serial ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7893SQ-10 | Same die, identical electrical specs, but commercial-grade screening (not Class S); Q-8 package | Lacks MIL-PRF-38535 Class S qualification, burn-in, and lot traceability; not approved for flight hardware | Select only for ground-test or non-safety-critical prototypes where cost sensitivity outweighs qualification requirements |
| ADS8320UB | 16-bit, 100 kSPS, SPI interface, +2.7 V to +5.5 V supply; no internal track/hold; requires external REF | Higher resolution but slower speed; lacks integrated track/hold and military temp range; different pinout and protocol | Choose when 16-bit precision is mandatory and system can accommodate external sample-hold and reference design |
Compared with AD7893SQ-10, 5962-9475502MPA adds full MIL-PRF-38535 Class S screening and documentation traceability, while ADS8320UB trades speed and integration for resolution and voltage flexibility-neither is pin-compatible nor drop-in replaceable.

FAQ
What is the absolute maximum analog input voltage rating for 5962-9475502MPA?
The absolute maximum analog input voltage for 5962-9475502MPA is ±17 V referenced to AGND. This rating applies specifically to the AD7893-10 variant embodied by 5962-9475502MPA. Exceeding this voltage may cause permanent damage, even if within normal operating temperature range. Always limit input transients with external clamping diodes or series resistance when interfacing to noisy or unconditioned sources.
Does 5962-9475502MPA require an external reference voltage source?
Yes, 5962-9475502MPA requires an external +2.5 V reference applied to the REF IN pin. The part includes an on-chip buffer, but the reference must be stable, low-noise, and capable of sourcing ≤2 µA. Recommended sources include the AD780 or AD680 precision references. Reference inaccuracies directly translate to gain and offset errors in the 5962-9475502MPA's transfer function.
What is the serial data format output by 5962-9475502MPA?
5962-9475502MPA outputs a 16-bit serial frame on SDATA: four leading zeros followed by the 12-bit conversion result in twos-complement format (for ±10 V range). Data is clocked out MSB-first on the rising edge of SCLK and is valid on the falling edge. After the 16th falling SCLK edge, SDATA enters high-impedance (three-state) mode.
Can 5962-9475502MPA operate without a microcontroller interrupt signal?
Yes, 5962-9475502MPA does not require an interrupt signal. Its timing is fully controlled by the external CONVST and SCLK signals. Software can implement a fixed 6 µs delay after the rising edge of CONVST before initiating the 16-pulse SCLK read sequence. Alternatively, the falling edge of CONVST itself may serve as a hardware interrupt to trigger the read-no dedicated status pin is needed.
Is 5962-9475502MPA pin-compatible with other AD7893 variants like AD7893AN-10?
No, 5962-9475502MPA is not pin-compatible with plastic DIP (N-8) or SOIC (SO-8) variants. It uses the hermetic Cerdip (Q-8) package with different mechanical dimensions, lead finish, and thermal characteristics. While the pin functions (REF IN, VIN, AGND, etc.) match electrically, PCB layout, soldering profile, and mounting requirements differ significantly between Q-8 and N-8/SO-8 packages.
