Typical Applications
ADS7067 is suitable for 6 applications: Motor Control, Power Monitoring, Industrial Process Control, Portable Instrumentation, IoT Sensors, Data Acquisition Systems.
Motor Control
The ADS7067's 800-kSPS sampling rate and 16-bit resolution enable precise current and voltage sensing in motor control loops. Its small 16-DSBGA package fits compact motor drives, and the integrated reference reduces external components. The SPI interface allows easy connection to microcontrollers like the TMS320F28069, enabling fast, accurate feedback for field-oriented control.
Recommended
Power Monitoring
In power monitoring systems, the ADS7067 measures voltage and current with high accuracy. Its 16-bit resolution and 8 channels allow monitoring multiple phases or loads. The integrated reference ensures stable measurements over temperature. The SPI interface enables data transfer to a host processor like the MSP430F5529, supporting real-time power quality analysis and energy metering.
Recommended
Industrial Process Control
The ADS7067 is ideal for industrial process control, where multiple sensors (temperature, pressure, flow) need precise digitization. Its 8 multiplexed channels reduce component count, and the 800-kSPS rate supports fast control loops. The small package and low power consumption make it suitable for field transmitters. The SPI interface connects to PLCs or MCUs like the TM4C1294, enabling accurate monitoring and control.
Recommended
Portable Instrumentation
For portable instruments like handheld multimeters and data loggers, the ADS7067 offers high resolution and low power. Its 16-DSBGA package saves board space, and the integrated reference eliminates external components. The SPI interface allows connection to low-power MCUs like the MSP430G2553, enabling battery-operated designs with long life. The 800-kSPS rate supports fast measurements.
Recommended
IoT Sensors
In IoT sensor nodes, the ADS7067 digitizes analog sensor outputs with high precision. Its small size and low power consumption are ideal for battery-powered devices. The integrated reference reduces BOM cost, and the SPI interface connects to wireless MCUs like the CC2652R1. The 8 channels allow multiple sensors to be monitored, enabling smart agriculture, environmental monitoring, and predictive maintenance.
Recommended
Data Acquisition Systems
The ADS7067 is a key component in general-purpose data acquisition systems, providing 16-bit resolution and 800-kSPS sampling. Its 8 channels allow simultaneous monitoring of multiple signals. The SPI interface supports daisy-chaining for larger systems. The small package and integrated reference make it easy to integrate into compact DAQ modules. It pairs well with FPGAs like the LCMXO2-1200 for high-speed data capture.

- 16-bit resolution in small package (vs ADS61B23)
Design Notes
Decouple the AVDD and DVDD pins with 0.1uF and 1uF capacitors placed as close as possible to the pins. Use a low-impedance ground plane to minimize noise. The integrated reference requires no external capacitor, but a 0.1uF bypass on the REF pin is recommended for optimal performance.
For the 16-DSBGA package, ensure proper solder pad design per TI's application note. Use a 0.2mm via-in-pad or micro-via for the center pad to improve thermal and electrical performance. Route analog inputs away from digital traces to reduce crosstalk.
Avoid exceeding the absolute maximum ratings on the analog inputs. The PGA input range should be configured correctly to prevent clipping. Ensure the SPI timing meets the datasheet specifications, especially at high clock speeds. Use a series resistor on the SDO line if driving long traces.
Compliance Information
RoHS compliant per TI product page. Other compliance details not specified in provided data.
