MAX164CMRG/883B Visão geral
Background: A successive-approximation register (SAR) ADC is one of the canonical ADC architectures, sitting alongside flash, pipeline, and sigma-delta in the data-converter taxonomy. SAR ADCs use an internal DAC and comparator to binary-search the analog input against a reference, producing one N-bit code per conversion cycle. Their strength is excellent DC accuracy, deterministic latency, and low power consumption at moderate sample rates, which is why they dominate industrial, instrumentation, and military embedded systems where precise DC measurements and predictable response are required.
Key features of the MAX164CMRG/883B include 12-bit resolution, an integral non-linearity (INL) of +/-1 LSB maximum, and an internal 2.5V reference with +/-1.5% tolerance. The device exposes a parallel data interface for direct connection to microprocessors, and the built-in track-and-hold eliminates the need for an external sample-and-hold stage. The /883B suffix signifies MIL-STD-883B qualification for high-reliability and aerospace/defense applications.
The MAX164CMRG/883B is fabricated on a low-power CMOS process and uses a charge-redistribution DAC array that delivers true 12-bit performance without missing codes over the full military temperature range. The internal reference simplifies board layout by removing the external reference IC and bypass network, while the wide input bandwidth of the front-end T&H allows the converter to capture fast transient signals at full throughput without a separate buffer.
Typical applications include data acquisition systems in industrial control, precision instrumentation front-ends, military and aerospace telemetry subsystems, automatic test equipment (ATE), and process-control signal-conditioning modules. Designers choose this part when a 12-bit, 100 ksps SAR converter with an internal reference and MIL-spec screening is required in a through-hole footprint.
When designing with the MAX164CMRG/883B, note that the digital supply accepts a negative rail (-12V to -15V), which is uncommon for modern TTL-compatible SAR parts. By verifying that your digital logic levels match the MAX163B family, this part can replace older 12-bit ADC front-ends without redesign. Designers should follow the analog and digital ground separation recommendations in the datasheet.

Military / Aerospace Telemetry
The MAX164CMRG/883B is purpose-built for military telemetry subsystems where MIL-STD-883B screening and a rugged through-hole package are mandatory. Its 12-bit resolution and 100 ksps sample rate deliver sufficient accuracy for vibration, strain-gauge, and pressure transducer channels on flight data recorders, while the internal 2.5V reference removes drift sources across -55C to +125C operation. Engineers benefit from the parallel data interface that maps directly to legacy MIL-1553 / ARINC bus bridges without glue logic. The ceramic CDIP-24 package withstands vibration and thermal-shock profiles typical of tactical platforms, and the integrated track-and-hold captures transient events at full throughput without an additional buffer amplifier. Compared with commercial SAR ADCs, the /883B screening adds confidence for sustainment of legacy defense electronics.

Precision Industrial Data Acquisition
Industrial data-acquisition front-ends that digitize 0-5V transducer signals benefit from the MAX164CMRG/883B's 12-bit resolution, built-in 2.5V reference, and integrated track-and-hold. The reference tolerance and 100 ksps throughput cover most 4-20mA / 0-5V process-control loops after a current-sense amplifier. The parallel interface simplifies connection to legacy 8051 / 68k industrial controllers still common in PLC backplanes, while the SAR architecture provides deterministic latency that simplifies real-time control loops. The through-hole CDIP-24 package suits card-edge and backplane assemblies where surface-mount is not desirable. Designers must respect the negative digital supply requirement (-12V to -15V) when migrating to modern 3.3V logic controllers.
Recomendado
Automatic Test Equipment (ATE)
ATE platforms digitize multiple test points with deterministic latency and DC accuracy, both of which the MAX164CMRG/883B provides through its SAR core and internal reference. The 100 ksps throughput allows digitizing several channels per second through a multiplexer, and the 12-bit resolution delivers sub-0.1% full-scale accuracy after calibration. The integrated track-and-hold eliminates sample-rate-dependent gain error when muxing fast signals between channels, while the parallel interface minimizes read latency between conversion-start and result-read. The MIL-STD-883B screening supports ATE deployed in defense / aerospace manufacturing where high reliability and traceability are required, and the CDIP-24 through-hole package supports field-replaceable test instrumentation modules.
Recomendado
Process Control Signal Conditioning
Process-control analog front-ends digitize temperature, pressure, and flow signals from 4-20mA loops and 0-5V / 0-10V transducer outputs. The MAX164CMRG/883B's 12-bit resolution, 100 ksps sample rate, and built-in 2.5V reference cover typical DCS / SCADA signal ranges with no external reference required. The SAR architecture's inherent anti-alias behavior at the input simplifies the analog anti-alias filter design, while the parallel interface connects directly to legacy process controllers. The /883B screening and -55C to +125C temperature range make the part attractive for outdoor and refinery installations where commercial-grade ADCs would drift. The CDIP-24 through-hole package suits field-wired control cabinets that prioritize serviceability over board density.
Recomendado
Legacy Avionics Upgrades
Avionics sustainment programs replacing obsolete ADCs in legacy line-replaceable units (LRUs) find the MAX164CMRG/883B a direct-fit upgrade. Its 12-bit 100 ksps performance, internal reference, and parallel bus match older MAX16x / MAX17x designs that populated commercial and military avionics through the 1990s and 2000s. The MIL-STD-883B screening preserves DO-160 / MIL-STD-810 qualification status without requalification, and the CDIP-24 through-hole package allows drop-in PCB replacement without chassis rework. The integrated track-and-hold ensures capture of pulse-width-modulated avionics bus signals without external buffers, while the 2.5V internal reference simplifies calibration procedures in depot-level maintenance workflows.
Recomendado
Medical Instrumentation Front-Ends
Medical instrumentation front-ends that digitize physiological signals (ECG, EEG, EMG, pulse oximetry) benefit from the MAX164CMRG/883B's deterministic SAR latency and integrated track-and-hold. The 12-bit resolution is adequate for many diagnostic-class instruments after front-end gain, while the parallel data interface simplifies connection to legacy medical-grade microcontrollers and DSPs. The internal 2.5V reference provides low drift across patient-monitoring temperature profiles, and the /883B screening supports medical devices deployed in field hospitals and military medical units. The CDIP-24 through-hole package also benefits serviceability of medical equipment that prioritizes technician-replaceable modules over miniaturization.

Notas de projeto
The MAX164CMRG/883B requires both +5V analog/digital supplies and a negative -12V to -15V digital supply. Decouple each supply pin with a 10uF tantalum in parallel with a 0.1uF ceramic placed within 5mm of the package pin. Use separate analog and digital ground planes tied together at a single point near the AGND/REFGND pins to avoid digital switching noise coupling into the analog front-end.
The CDIP-24 through-hole package requires a socketed or wave-soldered card-edge assembly. Place the analog input trace as a guarded, low-impedance path directly from the front-end amplifier to pin 6 (AIN) to minimize leakage and pickup. Keep digital data bus traces (D0-D7, HBEN, CS, RD, CONVST) routed away from AIN, REFB, and REFGND to avoid digital-to-analog crosstalk during conversion.
Drive AIN through a low-impedance op-amp buffer (e.g., MAX410, OP-27, or equivalent) to settle the track-and-hold acquisition within the 100 ksps throughput window. The internal T&H requires the source impedance to settle below 1/2 LSB in less than the acquisition window; op-amps with >1 MHz GBW are typically sufficient for 0-5V unipolar inputs. Add an RC anti-alias filter (typically 10 kohm + 1 nF) at AIN for frequencies above 50 kHz.
Do not omit the negative digital supply (-12V to -15V); the device will not function with only +5V supplies. When reading 12-bit results via the 8-bit parallel interface, toggle HBEN to read the high nibble (D8-D11) before the low byte (D0-D7); reading only the low byte gives an 8-bit truncated result. The internal 2.5V reference cannot drive external circuitry beyond 1mA without affecting ADC linearity - keep reference loading minimal.
