ADC10664CIWMX/NOPB Descripción general
What is a successive-approximation / multi-step flash ADC? An ADC (analog-to-digital converter) translates a continuous analog voltage into a discrete digital code; the ADC10664 sits in the precision data-acquisition family that uses two lower-resolution flash conversions combined with a residue DAC to resolve higher bits in fewer full-scale steps. In the broader signal-chain taxonomy, the ADC10664 is an ADC -> data converter -> mixed-signal IC -> semiconductor. The integrated analog multiplexer lets one ADC share up to four single-ended sources, eliminating external analog switches in multi-channel scanning designs.
Key features of the ADC10664 include 10 bits of resolution, 4 single-ended analog input channels, a 1.5 MSPS sampling rate, parallel digital output interface, single-ended input type, and a flash-based multi-step architecture. The on-chip sample-and-hold eliminates the need for an external track-and-hold stage. Housed in a wide-body SOIC-28 package, the device is pin-compatible with TI's broader ADC1066x family and supports standard microprocessor parallel bus read cycles.
Architecturally, the ADC10664 uses TI's patented multistep conversion technique that performs two lower-resolution flash conversions and combines them via a switched-capacitor DAC, balancing speed against power dissipation. A self-calibrating ground-reference scheme referenced to the analog supply rejects offset drift over temperature.
Typical applications include process control instrumentation, multiplexed data-acquisition front ends, digitizing oscilloscope input stages, industrial sensor digitizers, and portable instrumentation. The 4-channel input multiplexer makes it well suited for multi-sensor scanning systems. The single +5 V supply simplifies board-level power design in mixed 5 V / 3.3 V systems.
When designing with this part, take care that the analog input does not exceed the supply rails, place a small RC anti-alias filter in front of each MUX channel, and provide a low-impedance reference decoupling network to keep the internal DAC well settled.

Aplicaciones típicas
ADC10664CIWMX/NOPB es adecuado para 6 aplicacións: Process Control Data Acquisition, Multiplexed Sensor Digitizer Module, Digital Oscilloscope Front-End Digitizer, Portable Instrumentation / Battery-Operated Testers, Medical Patient Monitoring (Non-Critical), Automotive Sensor Interface Module.
Process Control Data Acquisition
The ADC10664's 4-input analog multiplexer and 1.5 MSPS sampling rate are well suited to multi-channel industrial process-control boards that read several sensors (pressure, temperature, flow) through a single ADC. Operating from a single +5 V supply over the -40 °C to +85 °C industrial temperature range, it directly meets PLC and DCS front-end requirements. The integrated sample-and-hold removes the need for an external track-and-hold stage, shrinking BOM cost per channel. The parallel digital output streams data into an FPGA or microcontroller data bus at full 1.5 MSPS without DMA bottlenecks. Designers typically pair it with an external low-noise reference (REF02 family) to keep absolute accuracy within the 10-bit budget over the full temperature range.
Recomendado
Multiplexed Sensor Digitizer Module
The 4 single-ended inputs make the ADC10664 a natural fit for scanning up to four sensor sources in sequence. The 1.5 MSPS rate, divided by 4 channels, yields up to 375 kSPS per channel, which is appropriate for vibration, strain-gauge, and load-cell modules used in industrial weighing platforms. Its 235 mW dissipation keeps the junction temperature rise modest without active heatsinking, supporting compact IP65-rated enclosures. The wide-body SOIC-28 footprint gives enough thermal mass for continuous operation at industrial ambient temperatures. Channel-to-channel switching is handled inside the chip with break-before-make logic documented in the datasheet, eliminating external analog-switch crosstalk concerns.
Recomendado
Digital Oscilloscope Front-End Digitizer
The 1.5 MSPS sampling rate and 10-bit resolution are adequate for low-bandwidth oscilloscope front-ends and waveform digitizers used in bench tools and educational lab equipment. The 360 ns conversion time supports single-shot transient capture below 1 MHz signal bandwidth, which covers audio-frequency and slow-edge digital signal analysis. The parallel output interface allows direct DMA into an FPGA capture buffer without latency from serial protocols. Designing with the ADC10664 in this context means providing proper input-protection clamps and AC-coupling because the input range equals the supply rail. The wide-body SOIC package simplifies hand-soldered prototypes for lab-instrument development cycles.
Recomendado
Portable Instrumentation / Battery-Operated Testers
Battery-powered field testers benefit from the ADC10664's relatively low 235 mW dissipation, allowing several hours of operation from a single Li-ion cell when downsampling below 100 kSPS. The single +5 V supply requirement can be derived from a small boost converter or a USB rail, simplifying portable enclosure design. The 4-input MUX lets a single handheld instrument scan a thermocouple, a pressure sensor, a battery monitor, and a calibration source sequentially. The industrial temperature grade ensures reliability in outdoor and field-deployed tools. Add a low-power MCU such as an MSP430 to sequence conversions and forward data over Bluetooth or USB-CDC.
Recomendado
Medical Patient Monitoring (Non-Critical)
The ADC10664 can be used in non-life-critical medical monitoring peripherals such as spirometer flow sensors, body-temperature probes, or pulse-oximeter front-ends where 10-bit resolution at 1.5 MSPS is sufficient. The integrated MUX simplifies multi-sensor patient-cable designs, while the industrial temperature range covers hospital and home-care environments. Designers must implement the IEC 60601 isolation barrier externally because the ADC10664 does not include on-chip galvanic isolation. Add a precision op-amp front end and an external low-noise reference for the required signal-to-noise ratio; medical designs also need the appropriate IEC 60601-1 verification at the system level. The /NOPB lead-free package supports RoHS compliance required in modern medical designs.
Recomendado
Automotive Sensor Interface Module
Although the ADC10664 is industrial-grade rather than AEC-Q100 qualified, it can still be deployed in non-safety automotive subsystems such as cabin HVAC sensors, battery-pack telemetry interfaces, or infotainment auxiliary inputs. The 4-input MUX supports up to four automotive sensors sharing one ADC channel, reducing wire harness complexity. Designers must add input-protection (TVS diodes, series resistors) to meet automotive load-dump and ESD requirements because the ADC10664 does not include on-chip automotive-grade protection. The wide operating temperature range handles under-hood and cabin environments, and the SOIC-28 footprint simplifies PCB rework in prototyping.

Notas de diseño
Estimated: the ADC10664 draws approximately 47 mA from the +5 V supply at full 1.5 MSPS operation (235 mW / 5 V ≈ 47 mA). When downsampling in portable designs, average supply current scales roughly linearly with the conversion rate. Place a 10 µF tantalum bulk capacitor plus a 100 nF ceramic decoupling capacitor within 5 mm of the AVDD and DVDD pins; keep the analog and digital ground returns separate and join them at a single star point under the ADC to avoid digital switching noise coupling into the analog reference.
Route the analog input traces as a differential pair with a grounded guard to minimize common-mode pickup. Keep digital output traces (D0-D9, RD, CS, INT, CONVST) away from the analog input traces and the VREF traces, using a ground guard trace on both sides. The 28-SOIC wide-body footprint has 0.07 inch lead pitch and tolerates 0.1 µF bypass capacitors placed directly under the package body between pins 5-8 and 19-22. Use a low-impedance power plane on the AVDD/DVDD layer if possible, and avoid routing switching signals on the top layer under the ADC body.
Do not allow the analog input voltage to exceed AVDD or fall below AGND by more than 100 mV, even momentarily, because the input ESD structures can latch up. Always ensure the MUX is set to a valid channel (00, 01, 10, or 11) before issuing CONVST, because undefined MUX_ADDR values may produce invalid conversions. The external reference decoupling network (typically 10 µF + 100 nF) must be physically close to the VREF+ / VREF- pins; long trace inductance between the reference and the ADC's reference input introduces integral non-linearity and gain error. Finally, when cascading ADC10664s for >4 channel designs, do not share the same VREF rail without individual RC filtering per ADC to avoid cross-talk noise injection.
