Product details
Overview
JM38510/14001BXA from Analog Devices is a military-grade 12-bit monolithic analog-to-digital converter with successive-approximation architecture, internal 10 V reference, and ±55°C to +125°C operating range. It delivers ±1 LSB linearity error over full temperature range, supports unipolar (0 V to +10 V / +20 V) and bipolar (±5 V / ±10 V) input ranges, and integrates thin-film trimmed scaling resistors for absolute calibration - used in precision data acquisition subsystems of avionics flight control computers.
For engineers reviewing the JM38510/14001BXA datasheet, JM38510/14001BXA pinout, JM38510/14001BXA application, or JM38510/14001BXA equivalent, key selection criteria include guaranteed no-missing-codes performance at 11-bit resolution across –55°C to +125°C, full-scale calibration error ≤0.25% FS, and compatibility with MIL-STD-883 Class B screening per ordering guide footnote 2.
Technical Context
The JM38510/14001BXA implements a fully self-contained successive-approximation ADC core with on-chip 12-bit current-output DAC, comparator, SAR logic, and temperature-compensated buried Zener reference. Its analog front-end includes dual input scaling networks (5 kΩ for 10 V span, 10 kΩ for 20 V span) and a 10 kΩ bipolar offset resistor tied to REF OUT in bipolar mode.
Digital interface uses CE/CS/R/C/A0/12/8 control signals to support both 12-bit parallel and 8-bit nibble-read modes, with STS status output and three-state DB11–DB0 outputs. Conversion time is 15 µs (typ) to 35 µs (max) for 12-bit cycles, and the device requires ±12 V or ±15 V analog supplies plus +5 V logic supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12 bits - delivers 4096 discrete digital codes over full-scale analog input range |
| Linearity Error (TMIN to TMAX) | ±1 LSB - ensures maximum deviation of any code from ideal transfer curve across –55°C to +125°C |
| No Missing Codes Guarantee | 11 bits - all 2048 upper codes appear monotonically over full temperature range |
| Full-Scale Calibration Error | ≤0.25% of FS - corresponds to ≤10 LSB error at 10 V span, trimmable via external 50 Ω resistor |
| Internal Reference Voltage | 10.00 V ±0.02 V - laser-trimmed buried Zener with 1.5 mA output drive capability |
| Conversion Time (12-bit) | 15 µs (typ), 35 µs (max) - defines minimum sampling interval for dynamic signal capture |
| Supply Voltages | VCC = +11.4 V to +16.5 V; VEE = –11.4 V to –16.5 V; VLOGIC = +4.5 V to +5.5 V - mandates separate analog/digital rail regulation |
Pinout & Package
Ceramic DIP-28 (D-28) package with hermetic seal, compliant with MIL-STD-883 screening requirements for high-reliability aerospace and defense applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 28 | VLOGIC | +5 V logic supply - powers digital interface circuitry; decoupling required between Pin 28 and Pin 15 |
| 20 | VCC | +12 V or +15 V analog positive supply - powers internal DAC, reference, and comparator |
| 10 | VEE | –12 V or –15 V analog negative supply - required for bipolar operation and internal current sources |
| 9 | Analog Common (AC) | Primary analog ground reference - connects to internal reference and comparator; must be low-impedance node |
| 13, 14 | 10VIN, 20VIN | Unipolar analog inputs - 10VIN accepts 0 V to +10 V; 20VIN accepts 0 V to +20 V; input impedance 5 kΩ / 10 kΩ respectively |
| 6 | BIP OFF | Bipolar offset input - tied to REF OUT (Pin 8) for ±5 V/±10 V operation; grounded for unipolar mode |
| 8 | REF OUT | 10 V reference output - supplies 1.5 mA max; must remain constant during conversion; buffer recommended for ±12 V supplies |
| 12 | REF IN | Reference input - accepts external 10 V source; internally connected to REF OUT when unused |
| 3, 4, 5, 7 | CE, CS, R/C, A0 | Control inputs - CE/CS enable device; R/C selects convert vs read; A0 selects MSB/LSB byte in 8-bit mode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD574AKD | Commercial grade (0°C to +70°C); ±1/2 LSB linearity; 12-bit no-missing-codes guarantee | Not qualified to MIL-STD-883; unsuitable for extended temperature or radiation environments | Select when cost sensitivity outweighs environmental ruggedness and full military screening is unnecessary |
| AD574ATD | Military grade (–55°C to +125°C); ±1 LSB linearity; 12-bit no-missing-codes guarantee; 25 ppm/°C full-scale tempco | Higher tempco than JM38510/14001BXA (50 ppm/°C); identical package and pinout | Choose when tighter full-scale drift is required and ±1 LSB linearity remains acceptable |
Compared with AD574AKD and AD574ATD, JM38510/14001BXA provides the strictest full-scale temperature coefficient (50 ppm/°C) among military variants while maintaining MIL-STD-883 Class B compliance - making it optimal for systems where long-term calibration stability under thermal cycling is prioritized over minimal linearity error.

FAQ
What is the operating temperature range of the JM38510/14001BXA?
The JM38510/14001BXA is rated for operation from –55°C to +125°C, meeting MIL-STD-883 Class B environmental screening requirements. This range is validated across all electrical specifications including linearity error, full-scale calibration, and no-missing-codes performance - ensuring reliable operation in unheated aircraft bays and missile guidance sections.
Does the JM38510/14001BXA require external calibration components?
The JM38510/14001BXA includes laser-trimmed thin-film resistors and an internal 10 V reference, enabling operation without external calibration in many applications. However, unipolar offset (Pin 12) and full-scale (Pin 8 to Pin 10) trims are provided using external 100 kΩ and 100 Ω potentiometers respectively - allowing system-level adjustment to meet tighter accuracy targets.
How does the JM38510/14001BXA handle analog input drive requirements?
The JM38510/14001BXA demands a low-impedance analog source due to dynamic current modulation at its input node. Driving op amps must maintain stability under 500 kHz transient loads and settle within 1 µs. Recommended drivers include AD585 (for sampled systems) or AD711/AD544 (for DC-coupled applications), as specified in the AD574A datasheet Rev. B.
Can the JM38510/14001BXA interface directly with an 8-bit microcontroller bus?
Yes - the JM38510/14001BXA supports 8-bit nibble-mode operation via the 12/8 and A0 pins. When 12/8 is tied to Digital Common, A0 selects either the 8 MSBs (A0 = 0) or 4 LSBs + 4 trailing zeroes (A0 = 1), enabling direct connection to 8-bit address/data buses without external latches or buffers.
What is the power supply configuration required for bipolar operation of the JM38510/14001BXA?
Bipolar operation of the JM38510/14001BXA requires both ±12 V or ±15 V analog supplies (VCC, VEE) and +5 V logic supply (VLOGIC). The BIP OFF pin (Pin 6) must be connected to REF OUT (Pin 8), and analog inputs are applied to 10VIN (±5 V) or 20VIN (±10 V) terminals - with input impedance of 5 kΩ or 10 kΩ respectively.
