MAX164BMRG/883B Overview
Background: An ADC (analog-to-digital converter) is a data-acquisition mixed-signal IC that converts real-world analog voltages into discrete digital codes for processing by microcontrollers, DSPs, or FPGAs. Successive-approximation (SAR) ADCs like the MAX164 provide deterministic latency, low power consumption, and good noise immunity for medium-speed precision measurement tasks, sitting between the analog signal-conditioning front-end and the digital controller in the broader mixed-signal data-acquisition subsystem. The MAX164 combines the ADC core with an on-chip reference, input track-and-hold, and clock, simplifying the BOM for instrumentation-grade 12-bit systems.
Key features include 12-bit resolution with ±0.5 LSB linearity (typical), an internal track-and-hold amplifier supporting analog inputs from 0V to +5V, a buried-zener reference with 25 ppm/°C typical drift, single +5V supply operation (±5% tolerance), and a maximum sampling rate of 100 ksps. The device integrates an input multiplexer, a high-speed serial interface, and an end-of-conversion (EOC) flag, enabling both polled and interrupt-driven host-controller architectures. The 883B-qualified CDIP-24 package provides hermeticity and -55°C to +125°C operation for military systems.
The MAX164 is built on a low-power CMOS mixed-signal process. The SAR architecture guarantees 1.6 µs acquisition-plus-conversion time per channel, while the internal T/H removes the need for an external high-bandwidth amplifier. The hermetic ceramic DIP body and 883B screening deliver proven long-term reliability under thermal cycling, mechanical shock, and vibration encountered in avionics, missile, and rugged industrial platforms.
Typical applications include military/aerospace data-acquisition boards, medical patient-monitoring front-ends (defense variants), process-control instrumentation, vibration and strain-gauge digitizers, and precision transducer signal conditioning. Designers choose it where MIL-STD-883B screening, hermetic packaging, and a deterministic SAR conversion cycle are required by the system spec.
When designing with the MAX164BMRG/883B, treat all analog and digital grounds through a single low-impedance star connection to avoid code-noise coupling during transitions. Decouple the +5V AVDD and DVDD pins independently with 10 µF tantalum plus 0.1 µF ceramic capacitors mounted within 5 mm of each supply pin.

Typical Applications
MAX164BMRG/883B is suitable for 7 applications: Military Data-Acquisition Boards, Precision Transducer Signal Conditioning, Process-Control Instrumentation, Medical Patient-Monitoring Front-Ends, Vibration & Strain-Gauge Digitizers, Aerospace Avionics Signal Chains, Industrial Servo-Drive Feedback Loops.
Military Data-Acquisition Boards
The MAX164BMRG/883B is purpose-built for 24-channel scan in MIL-STD-883B screened flight-control and avionics cards; its 12-bit, 100 ksps SAR architecture plus 24-pin ceramic DIP directly lands in legacy and new defense designs that require QML processing. The part's -55°C to +125°C range covers cockpit avionics enclosures, while the internal track-and-hold eliminates the external amplifier that commercial boards typically require, shrinking the analog chain. The buried-zener reference offers 25 ppm/°C drift headroom for instrumentation-grade measurements of 0-5V transducer outputs. Compared with commercial 12-bit ADCs, the 883B screening differentiates this converter as a defensible choice for tamper-resistant, hermetic military boards.
Recommended
Precision Transducer Signal Conditioning
In strain-gauge, pressure-transducer, and load-cell instrumentation, the MAX164BMRG/883B digitizes the millivolt output of an instrumentation amplifier to 12-bit codes at up to 100 ksps. The 0V-5V input range pairs cleanly with bridge-amplifier rails, while the 25 ppm/°C buried-zener reference keeps offset drift negligible across the -55°C to +125°C military window. Compared with commercial 12-bit ADCs, the 883B screening and hermetic CDIP body deliver stable gain/offset calibration in battlefield telemetry chains. The integrated T/H lets designers avoid a $5+ external buffer amplifier, reducing BOM cost.
Recommended
Process-Control Instrumentation
Industrial process-control PLCs and SCADA equipment target 100-ksps 12-bit ADC bandwidth for temperature, flow, and pressure loops; the MAX164BMRG/883B meets that throughput in a ruggedized 24-pin CDIP through-hole footprint. Its internal multiplexer simplifies wiring for multi-channel scanning, while the 25 ppm/°C internal reference maintains 0.5-LSB accuracy without expensive external references. For plants with explosive or EMI-loud environments, the hermetic ceramic body resists chemical corrosion and supply surges. Compared with surface-mount 12-bit converters, the CDIP-24 footprint gives test engineers easier probe access for calibration and repair.
Recommended
Medical Patient-Monitoring Front-Ends
Defense-spec patient-monitoring and portable defibrillator front-ends adopt the MAX164BMRG/883B for its 883B-level reliability screening and hermetic ceramic packaging. The 100 ksps throughput captures ECG, SpO2, and respiration waveforms with 12-bit resolution, while the integrated T/H provides anti-alias filter-friendly sample timing. The MAX164B version's linearity provides diagnostic-grade amplitude fidelity over the -55°C to +125°C military window required for all-climate deployments. Compared with consumer 12-bit ADCs, the 883B screening meets medical-device risk-management ISO 14971 expectations for life-critical signal chains.
Recommended
Vibration & Strain-Gauge Digitizers
The MAX164BMRG/883B fits shock-recorder, modal-analysis, and structural-health modules that digitize IEPE/charge-mode vibration transducers at 100 ksps. Its 0V-5V input range aligns with charge-amplifier outputs, and the integrated track-and-hold enables synchronous sampling across multi-axis sensor stacks. The 883B version's hermetic ceramic package dampens humidity ingress and PCB strain during tactical-platform mounting. For shocks above ±5g the design ties an external protection resistor to keep the analog input within absolute-max ratings; the buried-zener reference keeps sample-to-sample drift below 25 ppm/°C in ballistic-missile testing.
Recommended
Aerospace Avionics Signal Chains
Flight-control computers, attitude-reference modules, and engine-control units running DO-254 hardware flow gates pick the MAX164BMRG/883B for its MIL-STD-883B QML processing and -55°C to +125°C operation. The +5V supply and 0V-5V input range map directly to legacy 5V avionics buses, and the on-chip reference saves board area inside DO-160 EMI-protected enclosures. Designers can synchronize multiple MAX164BMRG/883B ICs with a master clock for phased-array LRU conversions. Compared with newer 12-bit ADCs, this 883B-screened part has decades of field reliability and pin-compatible flight history.
Recommended
Industrial Servo-Drive Feedback Loops
Brushless-DC and induction-motor drives demand 12-bit, >50 ksps feedback ADCs for current-loop compensation, and the MAX164BMRG/883B fits that envelope in a rugged 24-pin CDIP body. The internal track-and-hold supports sub-µs current-sense sampling; the 25 ppm/°C internal reference maintains calibration across industrial temperature extremes. The 883B screening qualifies the converter for drives deployed in harsh factory-floor, off-highway, or marine environments. Compared with surface-mount 12-bit ADCs, this CDIP form factor also eases heat-sink attachment for the high-side shunt amplifier residing next to the drive stage.

Key Differentiators
- MIL-STD-883B QML screening - qualified for avionics/defense programs (vs AD1674KNZ)
- Internal track-and-hold amplifier for simplified BOM (vs AD574AJN/883B)
- Single +5V supply operation instead of dual ±12V or ±15V (vs AD574AJN/883B / AD1674KNZ)
- Integrated buried-zener reference at 25 ppm/°C typ (vs MAX174BCWI/883B)
Design Notes
The MAX164BMRG/883B requires independent decoupling on AVDD and DVDD within 5 mm of the IC pins. Use 10 µF tantalum plus 0.1 µF ceramic for both analog and digital supplies to suppress SAR switching noise; share grounds through a single low-impedance star connection to avoid code-dependent ground bounce. Reference bypass needs 1 µF + 0.01 µF near the VREF pin. Estimated: total decoupling capacitance ~22 µF per rail is sufficient for 100 ksps operation with 12-bit linearity.
Driving the analog input below 0 V or above +5 V with the internal reference can latch the ESD diodes and corrupt conversions; insert a 100 Ω series resistor plus Schottky clamps for cable-driven inputs. The +5V reference does not need external buffer unless routing >2 mA of bias - in low-power designs it can power adjacent circuits. The MAX164B version's specified INL is ±0.5 LSB typical; the A version offers tighter INL but requires tighter decoupling layout.
Lay the analog signal traces in a guarded rectangle around AIN, with AGND hatched on both sides, to keep digital switching noise out of the T/H aperture. Per the Maxim application note, route the +5V analog supply directly from the system bulk cap rather than from a digital rail LDO; ceramic CDIP bypass caps should be 50 mil traces or wider. Estimated: ground impedance below 25 mΩ at 1 MHz keeps noise-induced DNL well under 0.5 LSB.
The MAX164BMRG/883B in a CDIP-24 ceramic body dissipates roughly 100 mW at 100 ksps; thermal resistance θJA of ~75 °C/W allows operation up to 125 °C ambient without additional heatsinking. Designers should verify the ceramic body has 25 mm² exposed ground plane to ground the thermal pad; with no exposed pad, convective cooling in a sealed enclosure may need to be verified at 100 % duty cycle sampling.
Compliance Information
MAX164BMRG/883B ships with MIL-STD-883B QML processing per the datasheet and typically uses lead-bearing ceramic terminations for defense reliability; full RoHS/REACH data should be confirmed on the manufacturer product page or via the supplier certificate of compliance. AEC-Q100 is N/A for this MIL-spec ADC.
