Demonstration circuit 2425A features the LTC®2311 family. With up to 5Msps, these differential, single channel, 16-bit, serial, high speed successive approximation register (SAR) ADCs are available in a 16-lead MSOP package. The LTC2311 family has an internal 20ppm/°C maximum drift reference and an SPI-compatible serial interface that supports CMOS and LVDS logic. Note the demo board is configured for CMOS operation by default; see the note under JP3 for LVDS operation. The demo manual refers to the LTC2311, but applies to all members of the family, the only difference being the sample rate and/or the number of bits.
