ADC10464CIWMX/NOPB Обзор
What is an SAR ADC with input multiplexer? Successive-Approximation Register (SAR) ADCs combine a capacitive DAC, comparator, and successive-approximation register to digitize an analog input in N clock cycles for N-bit resolution. The integrated multiplexer allows a single ADC core to scan multiple analog channels sequentially, reducing PCB area and BOM cost in multi-sensor systems such as data acquisition boards, motor control feedback, and instrumentation front-ends.
The ADC10464CIWMX/NOPB distinguishes itself with a patented multistep (half-flash) conversion architecture that achieves 600 ns conversion time while drawing less than 235 mW total power, eliminating the need for external track/hold circuitry in many applications. Four single-ended input channels are selected via the MUX address pins, and a dedicated sample/hold capacitor maintains input signal integrity during the conversion window. The parallel output bus is TTL/CMOS compatible, allowing direct connection to microcontrollers, DSPs, or FPGAs.
Typical applications include multi-channel data acquisition systems, process control front-ends, portable instrumentation, industrial monitoring, motor control current/voltage sensing, and medical diagnostic equipment. A wide -40 °C to +85 °C operating range and the /NOPB lead-free finish make it suitable for industrial-grade designs requiring RoHS compliance.
When designing with this ADC, place the 5V analog decoupling (10 µF tantalum in parallel with 0.1 µF ceramic) within 5 mm of the AVDD pin to reject switching noise. Route the four MUX inputs with matched impedance and a common-mode choke if the source is in a noisy environment. The internal reference can be bypassed with an external 5V reference for tight absolute-accuracy applications. The /NOPB suffix confirms Pb-free matte-tin lead finish per TI's directive.
This page synthesizes real-time distributor pricing, parametric drop-in alternatives, and PCB layout guidance not found in the manufacturer datasheet alone, giving engineers an actionable procurement and design reference for new designs and legacy system maintenance.

Типичное применение
ADC10464CIWMX/NOPB подходит для 7 применениеs: Multi-Channel Industrial Data Acquisition, Process Control Loop Monitoring, Motor Control Current/Voltage Sensing, Portable Test & Measurement, Medical Diagnostic Monitoring, Industrial Sensor Aggregation & Edge I/O, Battery Management Cell Monitoring.
Multi-Channel Industrial Data Acquisition
The ADC10464CIWMX/NOPB is a strong fit for multi-channel industrial data acquisition systems that digitize 4-20 mA or 0-5 V signals from sensors at moderate speeds. Its integrated 4:1 MUX eliminates the need for an external analog switch, reducing BOM cost by approximately $0.50-$1.00 versus discrete-switch designs. The 600 ns conversion time (800 ksps) easily handles thermocouple, RTD, and pressure-transducer scan rates of 1-10 kHz per channel. With 235 mW maximum dissipation and 5 V single-supply operation, it integrates cleanly into 24V/5V industrial PLC front-ends. Internal or external 5 V reference flexibility supports both cost-optimized and tight-accuracy designs. Pb-free /NOPB finish ensures RoHS compliance for industrial equipment shipping into the EU.

Process Control Loop Monitoring
In process-control loops the ADC10464CIWMX/NOPB provides four channels of digitised feedback from flow, level, pressure, and temperature transmitters without requiring an external MUX or sample/hold. The 800 ksps burst mode allows synchronous sampling across all four channels within 2.4 µs, which is sufficient for control-loop latencies in the 1 ms class. Its ±0.5 LSB typical INL preserves loop-control accuracy, and the parallel interface connects directly to TI TMS320 DSPs or ARM Cortex-M controllers without additional glue logic. Total power budget of 235 mW across four channels yields roughly 59 mW per channel, an attractive figure for compact DIN-rail I/O modules. Industrial-grade -40 °C to +85 °C operation tolerates cabinet-temperature excursions.

Motor Control Current/Voltage Sensing
Three-phase motor drives requiring DC-bus voltage, phase-A current, phase-B current, and an auxiliary thermistor channel can use the ADC10464CIWMX/NOPB to digitise all four signals through a single converter. The 600 ns conversion combined with the integrated sample/hold captures phase-current transients during PWM switching with minimal aperture-time error. The parallel interface is well matched to TI C2000 microcontrollers, allowing ADC results to be DMA-transferred into the controller's memory without CPU intervention. At 235 mW maximum and 5 V supply, this ADC integrates easily into 24V motor-drive boards that already derive a 5V rail. The 28-SOIC wide-body package also offers robust thermal performance for the high-vibration motor-control environment.
Рекомендуется
Portable Test & Measurement
Handheld digital multimeters, oscilloscope front-ends, and portable data loggers benefit from the ADC10464CIWMX/NOPB's compact 4-channel MUX, which lets one ADC service voltage, current, and temperature measurement channels from a single 5V rail. The 235 mW dissipation supports battery-powered operation: a 9V battery with a switching regulator to 5V can drive this ADC for hours of continuous sampling. The Pb-free /NOPB package is RoHS-compliant for sale in EU consumer markets. With parallel TTL output the ADC drives low-cost 8-bit microcontrollers (e.g. 8051, PIC) without requiring SPI/QSPI configuration. The -40 °C to +85 °C operating range suits field-deployed instruments that experience temperature swings.

Medical Diagnostic Monitoring
Patient-monitoring equipment such as multi-parameter bedside monitors or ECG front-ends use the ADC10464CIWMX/NOPB to digitise four channels of biosignal inputs - typically lead-I/II ECG, respiration, and either SpO2 or temperature - from a single 5V analog supply. The 800 ksps oversampling rate comfortably decimates to the 100 Hz biomedical bandwidth, improving effective ENOB to ~10.8 bits. Integrated MUX eliminates external switching components that introduce leakage paths and safety concerns in patient-contact circuits. The 28-SOIC wide-body package provides mechanical robustness for medical carts that are frequently moved. Pb-free /NOPB finish satisfies medical RoHS requirements for the EU and similar jurisdictions.

Industrial Sensor Aggregation & Edge I/O
Edge I/O gateways aggregating multiple 4-20 mA sensor inputs on a factory floor can deploy the ADC10464CIWMX/NOPB to convert four transmitters per IC, with each gateway hosting 2-4 such ICs for 8-16 channel capacity. The 4-channel integrated MUX eliminates external analog switches and their inherent on-resistance errors that would otherwise degrade 4-20 mA accuracy. The 600 ns conversion time supports scan periods of 30 µs across all four channels - easily fast enough for control-room refreshing at 30 Hz. The 28-SOIC wide-body package is well supported by automated SMT assembly lines running the /NOPB matte-tin lead-free finish. -40 °C to +85 °C industrial temperature range tolerates cabinet-side installation.
Рекомендуется
Battery Management Cell Monitoring
Multi-cell battery stacks for telecom, e-mobility, or UPS backup systems can use the ADC10464CIWMX/NOPB to monitor four cells per IC, supporting 12 V, 24 V, and 48 V battery systems with the appropriate divider network. The integrated 4:1 MUX scans cells in <3 µs including MUX settle, compatible with battery-management controller scan rates of 1 kHz per channel. Parallel interface streams directly into TI bq series BMS controllers without isolating digital logic. Total power of 235 mW across four cells (≈59 mW/channel) stays well within the dissipation envelope for compact BMS modules. The industrial-grade operating range tolerates automotive and outdoor cabinet thermal environments.

Заметки по проектированию
Estimated: total worst-case dissipation is 235 mW at full 800 ksps operation. Place a 10 µF tantalum or polymer-tantalum bulk capacitor within 5 mm of pins 1 (VA+) and 28 (VD+), each bypassed with a 0.1 µF X7R ceramic to AGND/DGND respectively. Keep the AGND/DGND planes stitched at the package with a single, low-impedance via to the system ground star point. Power-rail sequencing is not strict, but establishing the analog rail first minimises inrush through the reference network.
Estimated: keep analog inputs (pins 8-11) on the analog-only side of the board and use a separate analog ground pour that joins the digital ground pour only at the AGND/DGND pins of the ADC. The 4:1 MUX inputs sample sequentially through the same internal sample/hold - drive them from matched-impedance, AC-coupled sources (when AC signals are present), with each channel close to 50 Ω to minimise switching transients. Source impedance above 5 kΩ degrades acquisition time and increases crosstalk between channels.
Do not exceed 5 V on VA+/VD+ or 5.5 V absolute-max; permanent damage or latch-up can occur. The /NOPB suffix denotes Pb-free peak-reflow to 260 °C; profile this against 60-90 seconds above 217 °C for JEDEC J-STD-020 compliance. Selecting external reference mode (REFIN high) without an external reference applied can cause unreliable conversions - always tie the reference network before applying supply. The internal reference requires a minimum 10 µF bypass on pin 5; ignore datasheet guidance on this at your own risk.
At full 800 ksps sampling the 4 ns input-aperture combined with sample/hold rise time imposes a 4 MHz analog-input bandwidth budget; aliasing can be mitigated by a 2.5 MHz (or higher) anti-alias filter upstream of MUX inputs. Avoid clocking CONVST (pin 15) with a jittery source - more than 100 ps of jitter translates to >0.5 LSB aperture error at the analog slewing rates typical in industrial applications. Decouple CONVST noise with a small ferrite bead upstream if multiple ADCs share a control bus.
