LTC2387 18-Bit, 15 Msps SAR ADC

Linear Technology's LTC2387-18 is ideally suited for a wide range of applications. The combination of excellent linearity and wide dynamic range makes the LTC2387-18 ideal for high-speed imaging and instrumentation applications. No latency operation provides a unique solution for high-speed control loop applications. The very low distortion at high input frequencies enables communications applications requiring wide dynamic range and significant signal bandwidth.

To support high-speed operation while minimizing the number of data lines, the LTC2387-18 features a serial LVDS digital interface. The LVDS interface has one-lane and two-lane output modes, allowing the user to optimize the interface data rate for each application.
