LTC2306 - Linear Technology Corporation

LTC2306 12-Bit ADC

The LTC®2302/LTC2306 are low noise, 500ksps, 1‑/2‑chan‑ nel, 12-bit ADCs with an SPI/MICROWIRE compatible serial interface. These ADCs include 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 LTC2302/LTC2306.
