TLA2518 - Texas Instruments

TLA2518 Small 8-Channel 12-Bit ADC

The TLA2518 is an easy-to-use, 8-channel, multiplexed, 12-bit, 1-MSPS, 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 the ADC conversion process. The TLA2518 communicates via an SP.
