12-Bit 8-Channel SAR Analog-to-Digital Converter with Configurable Analog and Digital I/O

The TLA2528IRTER is a flexible 12-bit analog-to-digital converter designed for multi-sensor data acquisition and mixed-signal embedded systems. Developed by Texas Instruments, this device features eight multiplexed channels that can be independently configured as analog inputs, digital inputs, or digital outputs. This unique capability allows designers to combine ADC functionality with general-purpose I/O expansion in compact embedded designs.

The converter uses a high-performance SAR architecture and communicates through an I2C-compatible interface supporting speeds up to 3.4 MHz. An integrated internal oscillator manages ADC conversions, simplifying system design by eliminating the need for an external clock. With selectable I2C addresses and a compact WQFN-16 package, the TLA2528 is well suited for sensor monitoring, industrial control systems, portable instruments, and IoT devices that require flexible analog and digital interfacing.
