MAX164CCNG Übersicht
Key features include 12-bit resolution with no missing codes, a fast successive-approximation architecture with built-in track-and-hold for accurate dynamic input capture, an internal buried-zener reference trimmed for low drift, and a high-speed parallel microprocessor interface with chip-select and read-strobe control. The internal reference eliminates external reference components while maintaining tight absolute accuracy.
The MAX164 family is a member of the data-acquisition IC hierarchy: ADC -> successive-approximation ADC -> data converter -> signal-chain IC -> semiconductor. A successive-approximation ADC uses an internal DAC and comparator to binary-search the input voltage, achieving an excellent balance of speed, resolution, and low power consumption for 12-bit applications. Compared with flash ADCs, SAR converters offer far lower power at moderate speeds; compared with integrating ADCs (e.g., dual-slope), they offer much higher throughput.
Typical applications include industrial process-control data acquisition, portable instrumentation and battery-powered measurement, multiplexed data-logging systems, pen-tablet digitizers, robotics sensor interfaces, and embedded control loops requiring 12-bit absolute accuracy. The parallel interface simplifies connection to standard microprocessors and DSPs without external glue logic.
When designing with this device, place a 10uF decoupling capacitor close to VDD and AVCC pins, and use the recommended bypass network for the reference pins. The internal reference is trimmed but degrades slightly when sourcing external load current; ensure REF decoupling is sized accordingly. The MAX164CCNG is the 0C to +70C commercial-temperature variant; for industrial temperature range choose MAX164CEEG.

Typische Anwendungen
MAX164CCNG ist geeignet für 7 Anwendungs: Industrial Process-Control Data Acquisition, Portable Battery-Powered Instrumentation, Embedded Control Loop Feedback, Multiplexed Data-Logging Systems, Pen-Tablet and Digitizer Signal Capture, Robotics Sensor Interface Module, Medical Patient Monitoring (Legacy Designs).
Industrial Process-Control Data Acquisition
The MAX164CCNG fits industrial data-acquisition cards where 12-bit absolute accuracy and 100 ksps throughput are sufficient. The internal reference and integrated track-and-hold reduce external component count on a 4-20 mA loop interface or thermocouple signal chain. Its single 5V analog supply simplifies isolated DC/DC converters in field-mounted PLCs. Engineers typically place the MAX164CCNG at the input stage, multiplexer-selector downstream, with a microcontroller reading the parallel bus. Compared with higher-speed flash ADCs, the MAX164 offers far lower power and superior INL for DC measurements.
Empfohlen
Portable Battery-Powered Instrumentation
The MAX164CCNG's single 5V supply and CMOS process make it well-suited to handheld multimeters and portable calibrators. With 12-bit resolution and on-chip reference it draws modest quiescent current, preserving battery life for field service work. Parallel data output connects directly to microcontrollers with 8-bit data ports, eliminating external shift-register logic. The MAX164CCNG is more power-efficient than flash ADCs and faster than integrating types, fitting the precision-versus-speed trade-off of portable instrumentation. Use it as the ADC stage between sensor signal conditioning and a low-power MCU.
Empfohlen
Embedded Control Loop Feedback
The MAX164CCNG suits closed-loop motor-control and servo-feedback systems requiring 12-bit precision at the control-loop rate. The 100 ksps throughput easily oversamples motor-current feedback for digital PI or PID controllers. Its fast track-and-hold captures PWM-edge current spikes without aliasing, improving torque-ripple rejection. Compared with sigma-delta ADCs of equivalent bandwidth, the SAR architecture delivers zero pipeline latency-critical for deterministic control loops. Pair it with a microcontrollers GPIO for direct parallel handshaking.
Empfohlen
Multiplexed Data-Logging Systems
The MAX164CCNG is appropriate for data loggers that scan multiple sensors through an analog multiplexer, since the integrated track-and-hold re-acquires quickly between channel switches. At 100 ksps, a 16-channel mux system can sample each channel at >6 kHz, sufficient for most thermal and strain-gauge monitoring. The internal reference simplifies temperature-compensation calibration. Compared with integrated multi-channel ADCs, the MAX164CCNG plus external mux approach offers lower cost per channel for low-channel-count applications.
Empfohlen
Pen-Tablet and Digitizer Signal Capture
The MAX164CCNG suits pen-tablet digitizer boards where stylus position is captured by a sensing array sampled at moderate rates. The 100 ksps throughput allows up to ~50 kHz per channel in a 2-axis system, sufficient for cursor tracking at typical pen speeds. The internal reference ensures stable full-scale calibration across operating temperatures. Its parallel interface allows direct connection to embedded digitizer controllers without glue logic, simplifying the BOM and improving jitter control.
Empfohlen
Robotics Sensor Interface Module
The MAX164CCNG fits robotics sensor-interface PCBs where multiple analog sensors (force, position, current) feed back to a central controller. The integrated track-and-hold ensures accurate conversion of noisy motor-current signals, and the 12-bit resolution delivers adequate precision for force-feedback loops. The single 5V supply and through-hole PDIP package simplify prototyping on perf-board or breadboard platforms. Compared with higher-resolution modern ADCs, the MAX164CCNG offers lower cost for educational and hobbyist robotics platforms.
Empfohlen
Medical Patient Monitoring (Legacy Designs)
The MAX164CCNG was used in legacy patient-monitoring designs where 12-bit precision captures ECG, pulse-oximeter, or temperature signals at 100 ksps. The integrated track-and-hold accurately samples bioelectric signals up to a few kHz, and the internal reference provides stable DC calibration. Its commercial temperature grade suits indoor clinical environments. Modern medical designs typically migrate to 16/24-bit sigma-delta ADCs for diagnostic-grade accuracy, but the MAX164CCNG remains a cost-effective choice for non-diagnostic wellness equipment.

Designhinweise
Place a 10uF tantalum and 0.1uF ceramic decoupling capacitor as close as possible to the AVCC pin and a separate 0.1uF ceramic on VDD. The MAX164CCNG separates analog and digital supplies; tying them together without local decoupling can couple digital switching noise into the analog reference and degrade SNR by 6-10 dB. Recommended layout per Maxim datasheet: star-ground topology with AGND and DGND joined only at the ADC package.
Route the parallel data bus D0-D11 with matched trace lengths (within 1 cm) to prevent logic skew at full throughput. Place the MCU read-strobe (RD) and chip-select (CS) traces away from the analog input and reference traces to avoid coupling. Through-hole PDIP-24 packaging simplifies prototype debugging but limits high-density designs - plan a footprint-compatible SOIC variant for production migration.
Do not drive the analog input beyond ±15V; the ESD structure can be damaged. Add a series resistor and clamping diodes when the source is industrial (e.g., 24V bus). Failure to bypass the REF pin with the recommended capacitor network causes gain error of up to 1 LSB. The MAX164CCNG is commercial temperature grade only; using it below 0 C or above +70 C is out-of-spec and may yield incorrect conversions or device stress.
The internal track-and-hold has an acquisition time of approximately 1 us; allow at least 2 us settling time after multiplexer switching for full 12-bit accuracy. Source impedance above the datasheet value causes gain error and increased distortion. Add a unity-gain buffer (e.g., MAX4166) between the multiplexer and AIN if the source impedance exceeds the recommended value.
Compliance-Informationen
RoHS status not confirmed in the verified data; the '+' suffix variant (MAX164CCNG+) is the RoHS-compliant version per Maxim part numbering convention. AEC-Q100 not applicable (industrial/consumer ADC). Conflict-minerals status should be confirmed through the manufacturer's CMRT disclosure for production orders.
