The MAX1119EKA+T is an 8-bit analog-to-digital converter from Analog Devices, offering a sampling rate of 100k SPS. It features 2 multiplexed input channels and uses an SPI interface for straightforward digital communication. The device includes an internal reference and operates over -40°C to 85°C. Packaged in a tiny SOT-23-8, it is designed for applications where board space is at a premium, such as portable instruments, industrial sensors, and consumer electronics.
- Fast Sampling: 100k SPS enables real-time digitization of dynamic signals like motor currents or audio envelopes.
- Small Footprint: SOT-23-8 package minimizes PCB area, ideal for compact consumer and industrial products.
- Simple Interface: SPI protocol is widely supported and allows high-speed data transfer with minimal wiring.
- Internal Reference: Eliminates the need for external reference components, reducing BOM cost and design complexity.
- Dual Channels: Two multiplexed inputs provide flexibility for monitoring two different signals without an external mux.
Simple Data Logging
The 8-bit resolution and 100k SPS sampling rate are sufficient for logging temperature or voltage trends in environmental monitoring systems.
Motor Control Feedback
In small DC motor controllers, the 2-channel input can sense current and position, with SPI providing fast data transfer to the control loop.
Battery Charger Monitoring
The internal reference and 2 channels allow monitoring of battery voltage and charge current in portable chargers, with the SOT-23 package fitting into compact PCBs.
Industrial Alarm Systems
With a -40°C to 85°C range, this ADC can digitize analog sensor outputs in industrial alarm panels, ensuring reliable operation in harsh environments.
Consumer Electronics
In devices like smart speakers, the 2-channel ADC can process analog knobs or sliders, converting user input into digital commands via SPI.
Automotive Aftermarket Sensors
The small footprint and SPI interface make it easy to add analog sensor inputs to automotive add-on modules like tire pressure monitors.
