LTC2386-18 - 18-Bit, 10Msps SAR ADC

The LTC®2386-18 is a low noise, high speed, 18-bit 10Msps successive approximation register (SAR) ADC ideally suited for a wide range of applications. The combination of excellent linearity and wide dynamic range makes the LTC2386-18 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 LTC2386-18 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.
