Small 8-channel 12-bit analog-to-digital converter (ADC) with SPI interface and GPIOs

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 SPI compatible interface and supports averaging multiple data samples with a single start of conversion. The built-in programmable averaging filters help reduce noise from the analog inputs and reduce the number of data samples required to be read by the host.
