Product details

Overview

JM38510/14002BXA from Analog Devices is a military-grade 12-bit monolithic analog-to-digital converter with internal 10 V reference, ±1 LSB linearity error over –55°C to +125°C, 35 µs max 12-bit conversion time, and dual unipolar/bipolar input ranges (0–10 V, ±5 V, ±10 V). It operates from ±12 V or ±15 V analog supplies and +5 V logic supply, and is used in ruggedized data acquisition systems for avionics, missile guidance, and spaceborne telemetry.

For engineers reviewing the JM38510/14002BXA datasheet, JM38510/14002BXA pinout, JM38510/14002BXA application, or JM38510/14002BXA equivalent, this page delivers verified specifications, MIL-STD-883B-screened package details, true 12-bit no-missing-codes performance at temperature extremes, and validated alternatives for high-reliability system design.

Technical Context

The JM38510/14002BXA implements a successive-approximation architecture with an internal 12-bit current-output DAC, comparator, SAR, and temperature-compensated buried Zener reference. It requires no external timing components and supports both 12-bit parallel and byte-mode (8+4) readout via CE/CS/R/C/A0/12/8 control logic.

It features programmable input span selection (10 V or 20 V unipolar; ±5 V or ±10 V bipolar), adjustable unipolar/bipolar offset trim, full-scale calibration adjustment, and status flag (STS) output. Input impedance is 5 kΩ (10 V span) or 10 kΩ (20 V span), and reference output supplies up to 1.5 mA with ±0.2% initial accuracy.

Key Specifications

11, 28	V_CC, V_EE	+12/+15 V and –12/–15 V analog supplies - power DAC, reference, and comparator; require local RC filtering

Key Features

Feature	Design Value

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, same D-28 ceramic package	Not screened to MIL-STD-883B; unsuitable for extended temperature or high-reliability deployment	Select only for cost-sensitive, non-military prototypes or ground-test equipment where environmental stress is controlled
AD1674KN	Integrated sample-and-hold + 12-bit SAR; 10 µs total throughput; plastic DIP-28; ±1 LSB linearity over 0°C to +70°C	Eliminates need for external SHA but lacks internal reference and MIL qualification; lower power (300 mW)	Choose when system-level speed > accuracy, and when board space is constrained - not a drop-in replacement for JM38510/14002BXA

Compared with JM38510/14002BXA, AD574AKD offers tighter linearity but no military screening or extended temperature operation, while AD1674KN integrates sample-and-hold at the expense of reference independence and environmental robustness - making JM38510/14002BXA the sole choice for certified airborne or spaceflight applications requiring guaranteed performance across –55°C to +125°C.

FAQ

What is the operating temperature range of the JM38510/14002BXA?

The JM38510/14002BXA is specified for continuous operation from –55°C to +125°C, fully qualified per MIL-STD-883B Method 5005.2 temperature cycling and Method 1010.8 steady-state life testing. This range is validated across all electrical parameters including linearity, conversion time, and reference stability - no derating required within these limits.

Does the JM38510/14002BXA require external clocking or timing components?

No. The JM38510/14002BXA contains a fully integrated successive-approximation register, comparator, and internal clock generator. It requires only valid CE/CS/R/C control signals and stable power supplies - no external crystal, oscillator, or timing IC is needed to achieve its rated 35 µs 12-bit conversion time.

Can the JM38510/14002BXA operate from ±12 V supplies instead of ±15 V?

Yes. The JM38510/14002BXA supports V_CC = +11.4 V to +16.5 V and V_EE = –11.4 V to –16.5 V. When using ±12 V, the internal 10 V reference remains stable, but external buffering of REF OUT is recommended if driving loads >0.5 mA across temperature - per Analog Devices Application Note AN-286.

How is the 12-bit result read from the JM38510/14002BXA in an 8-bit microprocessor system?

The JM38510/14002BXA supports byte-mode readout via the A0 and 12/8 pins. With 12/8 tied to Digital Common, asserting A0 = 0 enables DB11–DB8 (MSB nibble); A0 = 1 enables DB3–DB0 plus four trailing zeros (LSB nibble). This allows direct connection to 8-bit data buses without external latches or shift registers.

Is the internal reference of the JM38510/14002BXA user-adjustable?

No - the internal 10 V buried Zener reference is factory-trimmed to ±0.2% and not user-adjustable. However, full-scale calibration error (at REF IN) and unipolar/bipolar offset can be trimmed externally using resistors connected to pins 8–10 and 12, respectively - preserving reference integrity while correcting system-level gain and zero errors.
