LTC2308 12-Bit ADC

The LTC®2308 is a low noise, 500ksps, 8-channel, 12-bit ADC with an SPI/MICROWIRE compatible serial interface. This ADC includes an internal reference and a fully differential sample-and-hold circuit to reduce common mode noise. The internal conversion clock allows the external serial output data clock (SCK) to operate at any frequency up to 40MHz. The LTC23.
