Texas Instruments  XTLA2528IRTER

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

The TLA2528 communicates via anI2C-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 eightI2C addresses can be selected for the TLA2528 by connecting a resistoron the ADDR pin.
