The TLA2528 is an easy-to-use, 8-channel, multiplexed, 12-bit, successive approximation register analog-to-digital converter (SAR ADC). The eight channels can be independently configured as either analog inputs, digital inputs, or digital outputs. The device has an internal oscillator for ADC conversion processes.

The TLA2528 communicates via an I2C-compatible interface and supports standard-mode (100 kHz), fast-mode (400 kHz), fast-mode plus (1 MHz), and high-speed mode (3.4 MHz). Up to eight I2C addresses can be selected for the TLA2528 by connecting a resistor on the ADDR pin.
