ADC10062CIWMX - 10-Bit 800kHz 2-Input ADC | Texas Instruments
MPN: ADC10062CIWMX ✗ Cuối đờiADC10062CIWMX Tóm tắt
An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous-time, continuous-amplitude analog voltage levels into discrete-time, discrete-amplitude digital codes. The 10-bit resolution places this part in the family of medium-resolution successive-approximation and flash converters commonly used in data acquisition, instrumentation, and embedded control. Within the broader taxonomy, the ADC10062 belongs to the hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. Flash and multistep flash architectures trade resolution headroom for conversion speed, making this part suitable for medium-bandwidth applications rather than high-precision 16-/24-bit measurement.
Key features of the ADC10062CIWMX include 10-bit resolution, 2 analog input channels, 800 kHz maximum sample rate, CMOS logic-compatible digital interface, and a wide SOIC-24 industrial-grade package with gull-wing terminations. The IC uses an innovative, patented multistep conversion technique that achieves flash-class throughput while keeping the analog input structure manageable for system integration. Operating temperature and supply range are consistent with industrial-grade data-acquisition front ends.
Architecturally, the multistep conversion technique divides the conversion into sub-ranges, performing coarse and fine quantization steps. This approach reduces the comparator count compared with a true full-flash converter at equivalent speed, lowering input capacitance and easing the drive requirement on the upstream op-amp or input buffer. Designers using this part typically apply an external sample-and-hold or buffer amplifier to maintain dynamic performance at full throughput.
Typical applications for the ADC10062CIWMX include industrial process control front ends, portable instrumentation, vibration and waveform analysis, motor speed and position feedback, sonar/radar IF digitizing (legacy designs), and general-purpose embedded sensing where 10-bit resolution is sufficient. The dual-input configuration supports differential or multiplexed single-ended measurements in compact boards. When designing with this part, note the obsolete lifecycle status and verify long-term availability through franchised distributors or consider modern pin-compatible successors from the same ADC1006x family. This page synthesizes distributor pricing, lifecycle status, and cross-reference guidance not found in the manufacturer datasheet alone.

Ứng dụng tiêu biểu
ADC10062CIWMX phù hợp cho 6 Áp dụngs: Industrial Process Control Front End, Portable Instrumentation and Data Logging, Motor Speed and Position Feedback, Waveform Analysis and Oscilloscope Front End, Legacy Sonar and IF Digitizing, Embedded Sensing and HMI Panels.
Industrial Process Control Front End
The ADC10062CIWMX's 10-bit resolution, 800 kHz sample rate, and 2-input multiplexer make it a long-standing choice for industrial process-control front ends digitizing 4-20 mA or 0-10 V process variables into microcontrollers or PLCs. The dual inputs simplify differential bridge measurements from pressure, flow, or temperature sensors, while the industrial -40C to +85C temperature grade supports factory-floor deployment. Place the ADC near the sensor, drive the analog input with a low-impedance op-amp buffer, and use the parallel CMOS interface for fast hand-off to the host MCU; engineers should verify long-term supply given obsolete status.
Được đề xuất
Portable Instrumentation and Data Logging
Battery-powered data loggers benefit from the ADC10062CIWMX's CMOS process, parallel interface, and moderate 800 kHz sample rate. The 10-bit resolution is sufficient for vibration, temperature, and pressure logging where 0.1% absolute accuracy is acceptable. Power decay places the ADC10062 in a sleep/idle state between conversions; given the obsolete classification, designers of new portable instruments should evaluate current-production 10-bit SAR ADCs with explicit low-power modes for longer battery life and modern supply guarantees.
Được đề xuất
Motor Speed and Position Feedback
Closed-loop motor control requires digitizing analog tachometer or resolver-derived voltages at moderate bandwidth, and the ADC10062CIWMX's 800 kHz throughput comfortably handles 4-pole motor feedback signals up to 200 kHz mechanical frequency. The 2-input mux allows simultaneous speed and current monitoring, simplifying BLDC and stepper driver designs. Place the ADC on the control board with proper ground isolation between power and signal domains, and note the obsolete lifecycle before committing to new motor designs.

Waveform Analysis and Oscilloscope Front End
Digital oscilloscopes and waveform analyzers in the medium-bandwidth class (audio, vibration, mechanical analysis) historically used 10-bit flash or multistep flash ADCs like the ADC10062CIWMX. At 800 kHz, the converter handles audio-bandwidth signals (up to ~400 kHz) without aliasing, with the 2-input mux supporting dual-channel oscilloscope channels in a low-cost instrument. Modern oscilloscope designs use higher-resolution SAR ADCs; for legacy repair, the CIWMX remains a viable substitute.
Được đề xuất
Legacy Sonar and IF Digitizing
The multistep flash technique pioneered in the ADC10062 family made these ICs often used in legacy sonar and intermediate-frequency (IF) digitizing applications where moderate 10-bit resolution and high sample rate were acceptable trade-offs for system simplicity. At 800 kHz the ADC10062 digitizes narrowband IF signals up to 400 kHz; designers should be aware that modern IF digitizing uses 12/16-bit pipeline ADCs at 40-250 MSPS for greater dynamic range. For legacy repair, the CIWMX remains a drop-in part.
Được đề xuất
Embedded Sensing and HMI Panels
Human-machine interface (HMI) panels and embedded sensor boards use the ADC10062CIWMX to read multiple analog signals (temperature, light, position potentiometer) into the host MCU. The 2-input mux simplifies scanning a primary and secondary analog sensor, while the parallel CMOS interface integrates with 8/16-bit microcontrollers without SPI overhead. For modern HMI designs with capacitive touch and higher integration, dedicated touch controllers and integrated MCU-ADCs are preferred; the CIWMX remains useful for legacy retrofits.

Ghi chú thiết kế
Estimated: The ADC10062CIWMX operates from a single +5 V analog supply (VCC) and +5 V digital supply (VDD), each typically drawing 10-30 mA low-power CMOS levels. Use local 10uF tantalum plus 0.1uF ceramic bypass capacitors on each supply pin, placed within 5 mm of the package. Decouple analog and digital grounds at a single point (star ground) under the package to prevent digital switching noise from coupling into the analog input through the ground plane.
The ADC10062CIWMX analog inputs present moderate input capacitance and require a low-impedance op-amp buffer (such as the OPA2277 or AD8055) capable of settling within 1/2 LSB (~ 0.5 mV at 5 V reference) within the acquisition window. Drive the analog input with a wideband buffer; a series 10-100 ohm resistor between buffer and ADC input can dampen charge-injection transients but increases settling time, so choose empirically.
Per the manufacturer datasheet, the ADC10061 and ADC10062 are obsolete and described for reference only. Do not specify the ADC10062CIWMX for new designs without an authorized supply agreement. For modern replacements, verify the pinout of any candidate ADC1003x or current 10-bit successor because the SOIC-24 mechanical package is shared but pin assignments can differ between families (especially VREF, AGND, and INT pins).
Thông tin tuân thủ
Part is obsolete per TI datasheet; RoHS/REACH/lead-free status was not explicitly stated in the verified web data. The non-NOPB suffix typically indicates SnPb lead finish, not Pb-free. For RoHS-required designs, use the ADC10062CIWM/NOPB variant.
