Présentation
Description
Key highlights:
- Automotive qualified (AEC-Q100) for harsh environments.
- Low power: 3.5 mW at 1 MSPS (5V supply).
- Integrated 16-channel multiplexer with auto-scan mode.
- Wide temperature range: -40°C to +125°C.
Ideal for automotive, industrial, and battery-powered systems requiring high-speed, multi-channel data acquisition. Packaged in a TSSOP-30 form factor.

Pinout
Pin Count: 38 pins
Key Functions:
- 16 analog input channels (AIN0-AIN15)
- SPI-compatible serial interface (CS, SCLK, SDI, SDO)
- Internal reference (REFIN/REFOUT) or external reference support
- Power supply pins (AVDD, DVDD)
- Control pins (CONVST, BUSY) for timing
- GPIOs for additional functionality
Designed for automotive applications, it operates at up to 1 MSPS with low power consumption.
Application
- Automotive Systems: Battery management, sensor monitoring (temperature, pressure), and infotainment.
- Industrial Automation: Process control, motor control, and data acquisition.
- Medical Devices: Portable diagnostics and patient monitoring.
- Test & Measurement: High-speed data logging and instrumentation.
Its robust design (AEC-Q100 qualified) ensures reliability in harsh environments, while low power and high throughput (1 MSPS) suit real-time applications.
